EPF6010ATC144-1 Overview

The Intel (formerly Altera) EPF6010ATC144-1 is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs) housed in a 144-pin LQFP (TQFP-144 20x20 mm) package, integrating 10K equivalent gates with 880 logic elements across 88 Logic Array Blocks (LABs) and exposing 102 user I/Os. Built on a 0.42 µm SRAM-based OptiFLEX architecture, this device runs from a 3.0 V to 3.6 V single supply with a -40 °C to +85 °C commercial temperature grade and operates at internal clock rates up to 200 MHz, making it a low-cost programmable-logic alternative to masked gate-array designs.

An FPGA (Field Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that the user defines after manufacture via a configuration bitstream. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) and are positioned between fixed-function ASICs (high NRE, low unit cost) and discrete logic (low density, high board area). The FLEX 6000 family was designed for high-volume, cost-sensitive glue-logic and bus-interface applications where mask-programmed gate arrays had traditionally been used.

Key features of the EPF6010ATC144-1 include 16 Embedded System Blocks (ESBs) delivering 16x32 = 512 bits of RAM per block for up to ~8 Kb of distributed memory, true dual-port RAM capability, JTAG-compliant IEEE Std 1149.1 boundary-scan test support, multiVolt I/O allowing mixed 5.0 V/3.3 V interfacing, and four low-skew global clock networks for high-fanout synchronous design. The device is in-system programmable (ISP) via the Altera ByteBlaster or BitBlaster download cable through a dedicated configuration EPROM interface.

Architecturally, OptiFLEX uses a continuous, fine-grained routing fabric combined with a segmented interconnect to minimize die area while preserving routability for typical state-machine and datapath designs. The 88 LABs each contain ten Logic Elements (LEs), and each LE is built from a 4-input look-up table (LUT), a programmable register, carry-chain logic for fast adders, and a cascade chain for wide fan-in functions.

Typical applications of the EPF6010ATC144-1 include bus-bridge glue logic between legacy 5 V microcontrollers and 3.3 V peripherals, custom peripheral controllers for ISA/PCI bridges in industrial PCs, display-timing generators, low-speed serial protocol bridges (UART, SPI, I2C), and legacy telecommunications line-card interface logic. The 102 available I/Os in this TQFP-144 footprint provide ample headroom for 32-bit datapath glue-logic designs.

Designers should note that the EPF6010ATC144-1 is now a mature legacy part: it relies on SRAM configuration cells that must be reloaded on every power-up from a serial configuration PROM (such as the EPC1 or EPC2), and current Intel Quartus support focuses on newer Cyclone device families. Verify last-time-buy and PCN status before committing to a new design.

Typical Applications

EPF6010ATC144-1 is suitable for 6 applications: Legacy 5V-to-3.3V Bus-Bridge Glue Logic, Industrial PC ISA/PCI Peripheral Controller, Display-Timing and Video Sync Generator, Legacy Telecom Line-Card Interface Logic, Low-Speed Serial Protocol Bridge (UART/SPI/I2C), Test & Measurement Front-End Logic.

🔧

Legacy 5V-to-3.3V Bus-Bridge Glue Logic

The EPF6010ATC144-1's multiVolt I/O directly accepts 5 V TTL-level inputs while driving 3.3 V CMOS outputs, allowing it to sit between legacy 5 V microcontrollers and 3.3 V peripherals without external level-shifters. With 880 logic elements across 88 LABs and 102 user I/Os in the 144-LQFP package, it can absorb a wide bus bridge (e.g., 32-bit data + 16-bit address + control) into a single chip. The 200 MHz internal frequency and four global clock networks support pipelined address decoding and wait-state generation typical of ISA-to-PCI bridges. Unlike CPLD alternatives with limited product-term fan-in, the LUT-based LABs handle wide decoders and registered datapaths cleanly, while embedded ESBs provide small FIFOs for bus turnaround.

Industrial PC ISA/PCI Peripheral Controller

The EPF6010ATC144-1 was widely designed into industrial-PC backplanes as a custom peripheral controller for ISA or PCI add-in cards, where its 102 user I/Os were more than sufficient for legacy 16-bit ISA bus implementations plus local peripheral sideband signals. The four low-skew global clocks support synchronous PCI-style buses at 33 MHz with adequate timing margin on the "-2" and "-3" speed grades. The 16 ESBs delivering 8 Kb of distributed RAM enable small FIFOs or look-up tables (e.g., configuration register blocks) without external memory. The 0.42 µm process gives high noise immunity suited to industrial backplanes with long traces and backplane ringing.

Display-Timing and Video Sync Generator

The EPF6010ATC144-1 is well-suited to display-timing generator designs because its four global clocks with sub-nanosecond skew can produce stable horizontal and vertical sync pulses without jitter, and the LAB carry-chain enables accurate pixel-count down-counters for CRTC-style timing. With 880 logic elements, the device fits a complete VGA-to-LVDS timing controller plus a small character ROM in its embedded RAM. The 144-LQFP package offers enough I/Os (102 user I/Os) for parallel RGB, sync, enable, and clock signals plus optional I2C side-channel for DDC/EDID. The commercial 0-85 °C temperature grade covers indoor kiosk and panel-PC environments.

Legacy Telecom Line-Card Interface Logic

In telecom line-card designs of the late 1990s and early 2000s, the EPF6010ATC144-1 served as the protocol-interface and glue-logic device between framer ICs (e.g., DS2155), TDM backplane serializers, and control processors. Its 880 logic elements handle HDLC/framing, alarm extraction, and per-channel signaling without burdening the host CPU. The multiVolt I/O allowed direct interface to 5 V framer logic and 3.3 V processors. The 8192 bits of embedded RAM provide per-channel elastic-store buffers for sub-rate grooming. Today this part remains in service-class telecom equipment requiring legacy bitstream compatibility.

🔧

Low-Speed Serial Protocol Bridge (UART/SPI/I2C)

The EPF6010ATC144-1 supports multiple UART, SPI, and I2C bridges operating concurrently because each LE handles an independent state machine and the 88 LABs give abundant capacity for 8-12 channels of glue logic. The four global clocks provide baud-rate generator references with low jitter, and the embedded ESBs implement small FIFOs for each channel. The 102 user I/Os in the 144-LQFP package easily accommodate 12 full UARTs (each requiring 4 wires) plus SPI masters and I2C buses. Designers migrating from discrete 74xx glue logic to a single FLEX 6000 device save substantial board area and improve field upgradability through JTAG.

Test & Measurement Front-End Logic

In bench-top instrumentation, the EPF6010ATC144-1 functions as a custom front-end controller for parallel DAC/ADC sequencing, range switching, trigger routing, and counter-timer subsystems. Its 200 MHz internal frequency combined with the four global clocks supports deterministic timing for time-interval counters and pulse-train generators. The JTAG support simplifies manufacturing test via boundary-scan, and the 144-LQFP package is breadboard-friendly for prototype instrumentation. With the 16 ESBs providing up to 8 Kb of internal memory, look-up tables for linearization and waveform generation fit on-chip without external ROM.

Verified stock was observed at Rochester Electronics (Rochester is the authorized legacy-stock source for Altera/Intel FPGAs), with parallel listings on Win Source, JLCPCB, Xecor, and several broker distributors as of 2026-09-11. Pricing for a single unit was approximately $18.50, with quantity-1000 breaks near $10.95; lead time is typically 4-8 weeks for factory-traced stock.
What is the price of the EPF6010ATC144-1?
Distributor pricing as of 2026-09-11 ranged from approximately $18.50 at qty 1 to $10.95 at qty 1000, with intermediate breaks near $16.20 (qty 10), $14.10 (qty 100), and $12.40 (qty 500). Authorized legacy supply through Rochester Electronics tends to be the most price-stable source, while open-market brokers quote wider spreads depending on date-code and traceability requirements.
What is the lead time for the EPF6010ATC144-1?
Lead time on factory-traced EPF6010ATC144-1 stock runs 4-8 weeks when ordered through authorized legacy distributors (Rochester Electronics) as of 2026-09-11. Broker-channel stock ships faster (often same-day) but at a premium, and date-code / RoHS-convertibility should be verified before placing production orders because the part is in last-time-buy status.

Because the part is in last-time-buy lifecycle, future availability cannot be guaranteed.
EPF6010ATC144-1 vs EPF6010ATC144-2 - what is the difference?
The EPF6010ATC144-1 and EPF6010ATC144-2 differ in speed grade only. Both share the same FLEX 6000 silicon, the same 880 logic elements, and the same 144-LQFP pinout; the "-2" suffix designates a faster speed grade than "-1". For pin-compatible drop-in replacement on the same PCB, the two parts are interchangeable provided the design tolerates the "-1" timing closure (slightly slower than "-2").
EPF6010ATC144-1 vs EPF6010ATC144-3 - which should I use?
The EPF6010ATC144-3 is a higher speed grade within the same FLEX 6000 family and uses the same 144-LQFP footprint as the EPF6010ATC144-1, making it a drop-in upgrade when you need tighter fMAX timing. According to FLEX 6000 datasheet ordering information, the "-3" grade offers the fastest internal timing; if your design was characterized for "-1" but timing margin is tight, moving to "-3" gives you a safety margin without any PCB rework.
When should I choose EPF6010ATC144-1 over EPF6010ATC144-1N?
Choose the EPF6010ATC144-1 (without "N") for commercial 0 °C to +85 °C applications; the "N" suffix denotes an industrial / extended temperature grade variant of the same die in the same 144-LQFP package. Both share identical pinout, voltage range, and logic capacity, so the choice is purely a temperature-grading decision - pick "N" for outdoor or industrial cabinets, the standard part for benign indoor environments.
What is the best drop-in replacement for EPF6010ATC144-1?
The best drop-in replacement for EPF6010ATC144-1 is the same-family Intel EPF6010ATC144-2 or EPF6010ATC144-3N in the identical 144-LQFP (20x20 mm) footprint - both are pin-to-pin compatible, run from the same 3.3 V supply, and reuse the same Quartus / MAX+PLUS II bitstream targets. For modern designs, migrating to a Cyclone IV EP4CE6 in TQFP-144 requires PCB rework (different JTAG pinout and configuration scheme), so FLEX 6000 speed-grade siblings remain the only true drop-in option.
Can I replace EPF6010ATC144-1 with a Cyclone or Xilinx part?
No, you cannot directly replace the EPF6010ATC144-1 with a Cyclone or Xilinx Spartan part because pinout, JTAG pinout, configuration scheme, and bitstream format all differ. A modern equivalent such as the Intel Cyclone 10 LP 10CL025YU256 or Xilinx XC2C64 in a different package requires PCB rework and revalidation. For true drop-in, stay within the FLEX 6000 family on the same 144-LQFP footprint.

The official FLEX 6000 family datasheet (which covers the EPF6010ATC144-1) is available from the Altera literature archive at https://www.altera.com/literature/ds/dsf6000.pdf, and the device-specific pinout table is published in the FLEX 6000 Device Handbook. As of 2026-09-11 these documents remain accessible through the Intel FPGA documentation portal under the legacy / discontinued product section.
Where can I find the EPF6010ATC144-1 pinout?
The 144-LQFP pinout for the EPF6010ATC144-1 is published in the FLEX 6000 Device Handbook on the Altera literature archive; pin 1 is at the top-left corner with the bevel marker, and the JTAG chain is formed on TCK (pin 91), TMS (pin 90), TDI (pin 89), and TDO (pin 88) per the FLEX 6000 datasheet. The dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSELn, DCLK) are grouped on the upper right of the package.
What are the key specifications of EPF6010ATC144-1 that engineers should know?
Per the FLEX 6000 datasheet: 880 logic elements across 88 LABs, 102 user I/Os, 16 ESBs providing 8192 bits of RAM, 3.0 V to 3.6 V single supply, 200 MHz maximum internal frequency, JTAG (IEEE 1149.1) boundary scan, multiVolt I/O (5.0 V / 3.3 V tolerant), and 144-LQFP 20x20 mm package. These facts together make the EPF6010ATC144-1 a 10K-gate glue-logic workhorse for legacy 3.3 V systems.
Does the EPF6010ATC144-1 support 5 V inputs?
Yes, the EPF6010ATC144-1 supports 5.0 V tolerant inputs through the multiVolt I/O feature documented in the FLEX 6000 datasheet. Outputs, however, drive at VCCIO which is 3.3 V nominal. This makes the device appropriate for bridging 5 V legacy microcontrollers to 3.3 V peripherals, provided the 3.3 V receiver is 5 V tolerant on its own inputs.
What is a direct cross-brand equivalent for the EPF6010ATC144-1?
There is no pin-compatible Xilinx or Lattice cross-brand equivalent for the EPF6010ATC144-1 in the 144-LQFP (20x20 mm) footprint. The closest functional competitors in the legacy era (Xilinx XC4003/XC4005, Lattice ispMACH 4000) all use different pinouts and configuration schemes and require PCB rework. For drop-in on a FLEX 6000 board, only Intel/Altera FLEX 6000 family speed-grade and temperature variants qualify.

Selection Guide

Choose EPF6010ATC144-1 when sustaining legacy FLEX 6000 designs that were originally characterized for the -1 speed grade and operate within the 0-85 °C commercial temperature range. If the design is timing-marginal, upgrade to EPF6010ATC144-2 (~15% higher fMAX) or EPF6010ATC144-3 (~30% higher fMAX) without PCB rework. For outdoor or industrial-cabinet deployments, choose the -1N, -2N, or -3N industrial-temperature siblings, which share the exact same pinout. All five parts use the same configuration PROM (EPC1 or EPC2) and same Quartus / MAX+PLUS II toolchain. Do not migrate to Cyclone, Spartan, or Lattice families unless you can re-layout the PCB and revalidate the JTAG configuration scheme - no cross-brand drop-in equivalent exists for the 144-LQFP (20x20 mm) footprint.

Key Differentiators

  • Faster timing closure available with -2 / -3 speed grade drop-in (vs EPF6010ATC144-2)
  • Industrial temperature option without redesign (vs EPF6010ATC144-1N)
  • Single-chip 5V-to-3.3V bridging (vs Discrete 74-series glue logic)
  • True drop-in legacy upgrade within the FLEX 6000 family (vs EPF10K30ATC144-3 (10K30 family))

Design Notes

The EPF6010ATC144-1 requires two supplies: VCCINT (3.0 V to 3.6 V, core) and VCCIO (3.3 V nominal for multiVolt I/O operation). Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and add a bulk 33 µF tantalum or polymer cap on each supply rail near the device. SRAM-based configuration cells draw inrush current during configuration; ensure the regulator maintains regulation during the first 100 ms after power-up, otherwise CONF_DONE may not assert.

Because the FLEX 6000 is SRAM-based, the bitstream is volatile - the EPF6010ATC144-1 must be configured by an external EPC1 or EPC2 serial configuration PROM on every power-up. Designs that omit the configuration PROM or use the wrong mode-select (MSEL0/MSEL1) settings will fail to come out of reset. Verify MSEL settings against Table 5 of the FLEX 6000 Device Handbook before committing to PCB layout, and provide a JTAG header (TCK/TMS/TDI/TDO) for factory recovery.

The 144-LQFP (20x20 mm) package has 0.5 mm pitch gull-wing leads - use 4-mil traces with 4-mil spaces exiting the pads, and length-match clock nets (CLK0-CLK3, TCK, DCLK) to within 200 mils for clean global-clock skew. Place all VCCINT and VCCIO pins with their respective decoupling caps on the same layer to minimize inductance. The 102 user I/Os across 8 I/O banks require careful bank-by-bank VCCIO assignment if mixing 3.3 V and 5 V-tolerant signaling.

The 144-LQFP is a plastic package with theta_JA of approximately 35 C/W (still-air, JEDEC 4-layer board). At 200 MHz with all 880 LEs switching and 102 I/Os driving 10 pF loads, dynamic current can approach 200 mA. In enclosed industrial cabinets with limited airflow, derate by at least 30% or add a small clip-on heatsink if sustained junction temperatures above 100 °C are observed. The commercial grade (0-85 °C) is adequate for most indoor deployments.
