EPF10K30EQC208-3N Overview

The Intel EPF10K30EQC208-3N is a member of the FLEX 10KE family of Field Programmable Gate Arrays (FPGAs), delivering 30,000 typical gates, 1,728 logic elements, and 24,576 RAM bits in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) package. Operating at a core voltage of 2.5 V on a 0.22 µm CMOS process, the device supports internal clock rates up to 200 MHz with a typical propagation delay of 0.6 ns and offers 147 user I/Os for board-level integration.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and programmable I/O cells that the user can program to implement arbitrary digital logic. FPGAs sit between fixed-function ASICs and software-driven microcontrollers in the system hierarchy: digital logic IC -> programmable logic -> FPGA -> System-on-Chip (SoC) FPGA. The FLEX 10KE family was Intel's (originally Altera's) industry-first embedded programmable logic device family with on-chip SRAM blocks, enabling System-on-a-Programmable-Chip (SOPC) integration via its embedded array blocks (EABs).

Key features include 216 Logic Array Blocks (LABs) organized across the device fabric, embedded array blocks providing dedicated SRAM for true dual-port or single-port memory functions, in-system programmability via the IEEE 1149.1 JTAG interface, and multi-voltage I/O support allowing 2.5 V, 3.3 V, or 5 V interfaces on the same die. The device's CMOS SRAM-based configuration memory supports unlimited reconfiguration cycles, making it ideal for prototyping and design iteration. The commercial temperature grade (0 °C to 70 °C) targets mainstream industrial and consumer embedded designs.

Typical applications include glue logic replacement, bus-bridging interfaces, custom state-machine controllers, DSP co-processing front-ends, and legacy system refresh designs where a programmable logic upgrade path is desired. The on-chip EABs allow implementation of small FIFOs, dual-port RAM, and ROM look-up tables without consuming general-purpose logic.

When designing with this part, remember that the SRAM configuration memory must be loaded on every power-up via a configuration PROM (EPC2, EPC8, or EPC16) or a microcontroller host. Pin compatibility within the FLEX 10KE family allows design migration across speed grades and package options on the same PCB footprint, simplifying inventory and second-source planning.

Typical Applications

EPF10K30EQC208-3N is suitable for 6 applications: Glue Logic and Bus Bridging, Custom State-Machine Controllers, DSP Co-Processing Front-End, Legacy System Refresh and Industrial Retrofits, Telecom Line-Card Interface Logic, Embedded Memory and FIFO Buffers.

🔧

Glue Logic and Bus Bridging

The EPF10K30EQC208-3N is ideally suited for glue-logic replacement between microprocessors, memory, and peripherals on legacy boards. With 1,728 logic elements and 147 user I/Os, it can replace dozens of 74-series TTL/CMOS parts while consolidating bus-protocol conversion logic. The 200 MHz internal clock and 0.6 ns propagation delay handle high-speed address/data bus multiplexing and timing-skew correction. Designers use the device to bridge 8/16/32-bit buses, generate chip-select decoders, and implement wait-state insertion logic. Pin compatibility across the FLEX 10KE 208-PQFP family allows design reuse when migrating speed grades or qualifying second sources.

🏭

Custom State-Machine Controllers

For implementing complex state machines and protocol controllers, the EPF10K30EQC208-3N delivers the right combination of LUT density, dedicated flip-flops, and JTAG debug support. Its 216 Logic Array Blocks provide ample registers for state encoding and pipelined control logic, while embedded array blocks (EABs) handle small FIFO and lookup-table memory. The 2.5 V core combined with selectable I/O voltages (2.5 V/3.3 V/5 V) simplifies integration with mixed-voltage legacy controllers. In-system programmability via the IEEE 1149.1 JTAG interface enables rapid state-machine iteration during prototype bring-up without IC swaps.

🎧

DSP Co-Processing Front-End

The EPF10K30EQC208-3N serves as a flexible DSP co-processor front-end for filtering, FFT pre-processing, and data-acquisition pipelines. Its 24,576 bits of distributed SRAM enable small-to-medium data buffers and coefficient tables, while the 200 MHz internal clock supports high-sample-rate front ends in conjunction with external ADC/DAC chips. Multi-voltage I/O banks allow direct interfacing with 5 V legacy ADCs and 3.3 V modern DSPs without level shifters. Designers can implement systolic FIR filters, FFT butterflies, and digital down-conversion stages in the same fabric, accelerating prototype DSP designs before ASIC migration.

🏭

Legacy System Refresh and Industrial Retrofits

When modernizing legacy industrial control or telecom boards, the EPF10K30EQC208-3N allows engineers to consolidate discrete logic, custom PAL/GAL arrays, and obsolete ASICs into a single reprogrammable device. Its commercial 0 °C to 70 °C operating range suits indoor industrial enclosures, while 5 V-tolerant I/O banks directly interface with original legacy bus transceivers. On-board JTAG reconfiguration lets field technicians update control logic without desoldering parts, ideal for retrofitting production lines. The SRAM-based configuration memory supports unlimited in-system firmware updates over a product's lifetime.

🌐

Telecom Line-Card Interface Logic

Telecom line cards often require dense programmable logic for HDLC framing, T1/E1 aggregation, and proprietary bus-protocol adaptation. The EPF10K30EQC208-3N offers 147 user I/Os to handle multiple serial links in parallel, while embedded array blocks (EABs) provide the dual-port RAM needed for small transmit/receive FIFOs. Its 200 MHz internal clock rate and 0.6 ns propagation delay enable low-latency serial protocol processing. The 2.5 V core minimizes power consumption on densely populated line cards, and the JTAG interface supports boundary-scan board test in high-volume manufacturing.

💡

Embedded Memory and FIFO Buffers

The EPF10K30EQC208-3N's 24,576 bits of on-chip dual-port SRAM, distributed across its embedded array blocks, are ideal for implementing small-to-medium FIFOs, dual-port buffers, and lookup tables. Each EAB can be configured as 256×8, 512×4, 1024×2, or 2048×1 true dual-port RAM, supporting independent read/write clocks. Combined with 147 user I/Os and 216 LABs for address generation and flag logic, the device fits applications such as video line buffers, communication FIFOs, and waveform look-up tables. Designers can trade off EAB count against general logic for memory- or logic-dominated designs.

What is the EPF10K30EQC208-3N and what family does it belong to?
The EPF10K30EQC208-3N is a Field Programmable Gate Array (FPGA) from Intel's FLEX 10KE family, originally introduced by Altera in 1999. According to the FLEX 10KE datasheet, it provides 30,000 typical gates, 1,728 logic elements, 24,576 bits of on-chip SRAM, and 147 user I/Os in a 208-pin Power Quad Flat Pack package. It operates from a 2.5 V core supply on a 0.22 µm CMOS process and supports internal frequencies up to 200 MHz.
How many user I/O pins does the EPF10K30EQC208-3N provide?
The EPF10K30EQC208-3N provides 147 user I/O pins distributed around the 208-pin PQFP package. According to the FLEX 10KE device handbook, the remaining pins are reserved for power (VCCINT/VCCIO), ground (GND), JTAG (TCK, TMS, TDI, TDO), and dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL, DCLK, DATA0). This I/O count supports mid-density logic designs and 32-bit parallel interfaces.
What configuration device is required for the EPF10K30EQC208-3N?
The EPF10K30EQC208-3N requires an external serial configuration PROM because its configuration memory is SRAM-based and volatile. According to Altera configuration documentation, compatible configuration devices include EPC2, EPC4, EPC8, and EPC16.

Lead time for the EPF10K30EQC208-3N as of 2026-09-11 typically ranges from 6 to 10 weeks, since the part is in its last-time-buy / obsolete phase per Intel's product change notices. Distributors such as Digi-Key and Mouser hold limited stock, while brokers like Jotrin and EOLSEMI may offer faster delivery but at premium pricing. Long-term production designs should plan for an immediate design migration to a newer Intel/Altera FPGA family.
Where can I download the EPF10K30EQC208-3N datasheet PDF?
The official FLEX 10KE datasheet PDF can be downloaded from the Altera/Intel legacy documentation archive at https://www.altera.com/literature/lit-flex10ke.jsp, and mirror copies are available from third-party providers such as ADAtasheet (adatasheet.com), DigiChip, and FindIC. According to these sources, the datasheet details device architecture, AC/DC characteristics, and configuration modes for the entire FLEX 10KE family including the EPF10K30E variant.
Where can I find the EPF10K30EQC208-3N pinout?
The full 208-pin PQFP pinout for the EPF10K30EQC208-3N is published in the FLEX 10KE device handbook. According to the datasheet, the package follows standard PQFP gull-wing lead ordering with pin 1 indicated by a marker dot. Pin functions include user I/O banks (I/O Bank 1-4), dedicated JTAG pins (TCK, TMS, TDI, TDO), configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0), PLL clock pins, and power/ground pins distributed for thermal performance.
What is a drop-in replacement for the EPF10K30EQC208-3N?
Drop-in replacements for the EPF10K30EQC208-3N in the same 208-pin PQFP package are the same-family speed-grade variants EPF10K30EQC208-3, EPF10K30EQC208-2N, EPF10K30EQC208-2, EPF10K30EQC208-1N, and EPF10K30EQC208-1, all sharing the FLEX 10KE architecture and pinout. According to the FLEX 10KE device handbook, these parts differ only in speed grade (commercial -1/-2/-3) and lead-free option, making them mechanically and electrically pin-compatible on the same PCB footprint.
Can EPF10K30AQC208-1N replace the EPF10K30EQC208-3N?
The EPF10K30AQC208-1N belongs to the FLEX 10KA family (lower-power, lower-density predecessor), not the FLEX 10KE family, so it is not a drop-in replacement. According to the Altera FLEX 10K family datasheet, the EPF10K30AQC208-1N provides fewer features (no enhanced embedded array blocks) and a different speed grade. Cross-family migration from 10KA to 10KE generally requires design re-synthesis and re-verification, not a pin swap.
What is the difference between FLEX 10KE and FLEX 10K FPGAs?
The FLEX 10KE family is an enhanced version of the original FLEX 10K family, with key improvements including faster on-chip RAM via Enhanced Embedded Array Blocks (EABs), support for 2.5 V core voltage, higher internal clock rates up to 200 MHz, and additional logic per LAB. According to the Altera FLEX 10KE datasheet, the E suffix denotes this enhanced feature set; otherwise the 10KE family is architecturally compatible with the 10K family for many design patterns.
What core supply voltage does the EPF10K30EQC208-3N require?
The EPF10K30EQC208-3N requires a 2.5 V core supply (VCCINT) with ±5 % tolerance per the FLEX 10KE datasheet. The device also supports multiple I/O bank voltages (VCCIO) of 2.5 V, 3.3 V, or 5 V depending on bank configuration, allowing mixed-voltage interfacing with 5 V legacy logic or 3.3 V microprocessors on the same die. Decoupling requires 0.1 µF ceramic capacitors adjacent to each VCCINT and VCCIO pin.
Is the EPF10K30EQC208-3N RoHS compliant?
RoHS compliance for the EPF10K30EQC208-3N is marked as [DATA_NEEDED] in this datasheet because legacy FLEX 10KE parts ship in both leaded and lead-free (Pb-free) variants depending on date code. The "N" suffix historically denotes a lead-free finish, but distributors should confirm RoHS compliance per specific lot. According to Intel PCN records, later production runs of FLEX 10KE parts were transitioned to lead-free finishes, but pre-2010 inventory may not be RoHS-compliant.
Hey Google, what can replace the EPF10K30EQC208-3N in a legacy design?
For a legacy design replacement of the EPF10K30EQC208-3N, the best same-footprint swap is any EPF10K30EQC208 variant (different speed grade within FLEX 10KE, same 208-pin PQFP). According to the FLEX 10KE device handbook, EPF10K30EQC208-1N (fastest), -2N, -3N, and the standard -1/-2/-3 versions all share the same pinout. For modern designs, migrate to Cyclone II EP2C5 (similar density, newer process) but PCB redesign is required.
What are the key specifications of EPF10K30EQC208-3N that engineers should know?
The key specifications of the EPF10K30EQC208-3N are: 30,000 typical gates, 1,728 logic elements, 24,576 bits of on-chip SRAM, 216 Logic Array Blocks, 147 user I/Os, 200 MHz internal clock, 0.6 ns typical propagation delay, 2.5 V core voltage, 0.22 µm CMOS process, and 208-pin PQFP commercial-grade package (0 °C to 70 °C). According to the FLEX 10KE datasheet, it supports JTAG (IEEE 1149.1) configuration, multiple I/O standards, and embedded array blocks for true dual-port RAM.

Selection Guide

Choose the EPF10K30EQC208-3N when designing or maintaining a legacy system that already uses the FLEX 10KE family on a 208-PQFP footprint and requires the slowest commercial speed grade (grade -3) for cost-sensitive applications. The 30,000 gates, 1,728 logic elements, 24,576 RAM bits, and 147 user I/Os in a 2.5 V core device make it ideal for glue-logic consolidation, bus bridging, and embedded state machines on industrial control or telecom line cards. Prefer the same-family speed-grade variants (-1N, -2N, -1, -2) as drop-in replacements if timing closure requires a faster Fmax - all share the identical 208-PQFP pinout per the FLEX 10KE device handbook. For new designs, consider migrating to Cyclone II EP2C5 or MAX V CPLD families because the FLEX 10KE is in last-time-buy/obsolete phase with limited future support.

Key Differentiators

  • Industry-first FLEX 10KE architecture with enhanced embedded array blocks (EABs) (vs EPF10K30AQC208-1N (FLEX 10KA family))
  • Pin-compatible 208-PQFP package across speed grades (vs EPF10K30EFC484-3N (484-pin BGA))
  • Multi-voltage I/O support (2.5 V, 3.3 V, 5 V) on the same die (vs EPF10K100EBC356-1 (Cyclone family predecessor))

Design Notes

The EPF10K30EQC208-3N requires a 2.5 V core supply (VCCINT) with ±5 % tolerance and four I/O bank voltages (VCCIO1-4) that can be independently set to 2.5 V, 3.3 V, or 5 V. Place 0.1 µF ceramic decoupling capacitors adjacent to every VCCINT pin (typically 8 distributed) and bulk 33 µF tantalum capacitors on each VCCIO bank. Estimated Icc current at 200 MHz with all I/O toggling is 250-400 mA; verify with worst-case test patterns from the FLEX 10KE PowerPlay tool.

For the 208-pin PQFP package, allocate at least 4 signal layers and one ground plane. Maintain 50 Ω controlled impedance on clock and JTAG traces and use 90 Ω differential routing for LVDS where applicable. Place the EPC2/EPC8 configuration PROM within 2 inches of the FPGA to avoid configuration-clock skew issues. Ensure pin 1 marker dot orientation matches the package land pattern; PQFP pin numbering increases counter-clockwise from the marker.

Estimated: configuration bitstream size for the EPF10K30E is approximately 160 Kbits. Selecting an undersized EPC2 (1 Mbit) PROM will cause configuration failures. Always tie nCONFIG high through a 4.7 kΩ resistor and add 1 µF bypass on the nSTATUS pin to suppress false configuration-start events during power-up. Do not leave MSEL pins floating - tie them to defined logic levels per the configuration mode (PS, AS, JTAG).
