EPF6024ATI144-1N Overview
A Programmable Logic Device (PLD) is an integrated circuit whose logic function is defined after manufacturing by the user, rather than at the fab. PLDs occupy a hierarchical position in the digital IC taxonomy: they are a subset of programmable logic, which also includes CPLDs (complex PLDs) and FPGAs (field-programmable gate arrays). The FLEX 6000 family from Altera pioneered low-cost, SRAM-based look-up-table logic in the late 1990s and was widely used in telecom line cards, industrial controllers, and PCI-bus bridge designs before being superseded by modern Cyclone and MAX families.
Key features include 2,560 logic elements (LEs), 4 embedded array blocks (EABs) providing 4 Kbits of RAM each, and fast interconnect with continuous routing across the device. The -1N speed grade indicates a faster timing bin and the "N" suffix denotes a lead-free / industrial qualification. The 144-pin TQFP footprint supports up to 117 user I/O pins via banked I/O with 3.3 V LVTTL/LVCMOS compatibility, easing integration into mixed-voltage legacy systems.
Typical applications include industrial automation controllers, telecom line interface glue logic, PCI/ISA bus bridges, video signal routing, and legacy ASIC replacement designs. The wide 3.0 V to 3.6 V core tolerance and JTAG-based in-system programmability (ISP) via the IEEE 1149.1 boundary-scan port simplify board bring-up and field updates.
When designing with this device, verify that the target Quartus II (or MAX+PLUS II) toolchain version supports the EPF6024A device ID, and budget sufficient decoupling (10 uF bulk + 0.1 uF per power pin) for the SRAM-based configuration cells. As an older member of the FLEX 6000 family, the EPF6024ATI144-1N is now in mature / last-time-buy status; verify long-term availability before committing to new designs.

Typical Applications
EPF6024ATI144-1N is suitable for 6 applications: Industrial Glue Logic Controller, Telecom Line Card Interface, PCI/ISA Bus Bridge, Video Signal Routing and Processing, Legacy ASIC Replacement, Test and Measurement Instrumentation.
Industrial Glue Logic Controller
The EPF6024ATI144-1N's 24,000 typical gates and 2,560 LEs make it a strong fit for industrial glue-logic controllers that integrate multiple discrete logic functions into a single programmable device. Its 117 user I/O pins in the TQFP-144 package provide ample connectivity for sensor multiplexing, motor-control interlocks, and legacy bus bridging. The 3.3 V LVCMOS I/O standard simplifies interfacing with 3.3 V microcontrollers and 5 V tolerant peripherals via external resistors. Designers can use the four 4-Kbit EABs for lookup-table-based waveform generation, encoder tables, or PID parameter storage, replacing entire logic ICs and reducing PCB area by 40-60 percent in retrofits of legacy PLC hardware.
Recommended
Telecom Line Card Interface
The EPF6024ATI144-1N is widely deployed in telecom line-card interface designs where its 172 MHz fMAX and JTAG-based in-system programmability enable rapid prototyping of TDM bus bridges, framer interfaces, and clock-distribution glue. The 3.3 V core supply aligns with telecom ASIC voltage rails, and the 117 user I/O support multi-drop TDM buses with per-pin timing closure. Its embedded array blocks (EABs) can implement small FIFOs or pattern-matching buffers for HDLC framing without external SRAM. The industrial -40 C to +85 C temperature range and lead-free N suffix make it compliant with telecom NEBS environmental requirements, suitable for central-office line cards and customer-premises equipment.
Recommended
PCI/ISA Bus Bridge
The EPF6024ATI144-1N serves as an effective PCI or ISA bus bridge in legacy computer systems where 33 MHz PCI timing is well within its 172 MHz fMAX capability. With 24,000 gates, designers can implement full PCI target state machines, configuration-space registers, and bus-arbitration logic in a single device. The TQFP-144 footprint provides sufficient I/O for 32-bit PCI plus auxiliary control signals, and the 3.3 V LVTTL I/O matches PCI signaling directly. Embedded array blocks can be configured as small transaction FIFOs to decouple PCI bus cycles from local logic, replacing discrete FIFO ICs and reducing BOM cost and board complexity in industrial single-board computers.
Recommended
Video Signal Routing and Processing
The EPF6024ATI144-1N's 2,560 logic elements and 117 I/O are well-suited to mid-complexity video routing, sync generation, and color-space conversion in broadcast auxiliary equipment. The 172 MHz internal frequency comfortably handles 27 MHz SDI pixel rates with substantial timing margin for synchronous logic paths. Designers can implement crosspoint switches, genlock circuits, and chroma-key mixers in a single PLD, eliminating multiple 74-series logic ICs from the BOM. The TQFP-144 footprint simplifies board layout for through-hole-friendly manufacturing and supports easy hand-prototyping of video broadcast reference designs.
Recommended
Legacy ASIC Replacement
The EPF6024ATI144-1N is frequently used as a drop-in replacement for obsolete ASICs in legacy industrial, medical, and aerospace systems where re-spinning the original ASIC is cost-prohibitive. By reverse-engineering the original ASIC's I/O behavior and logic function, designers can map the functionality into the FLEX 6000 architecture with 24,000 gates of headroom and 117 I/O matching most legacy gate arrays. The pin-compatible TQFP-144 footprint allows direct PCB swap without board rework. JTAG-based in-system programmability also enables late-stage design changes and field upgrades without re-masking, dramatically reducing NRE cost compared with a new ASIC tape-out.
Recommended
Test and Measurement Instrumentation
The EPF6024ATI144-1N's programmable architecture and 117 user I/O make it valuable in custom test and measurement fixtures where stimulus generation, response capture, and protocol decoding must be reconfigured per DUT. Engineers can implement arbitrary waveform generators, pattern sequencers, and protocol-state analyzers within the 2,560 LEs and four 4-Kbit EABs. The 172 MHz internal clock supports high-speed pattern sequencing, and the JTAG interface enables fixture reconfiguration between test cycles without removing the device. The industrial temperature range and lead-free N suffix meet quality requirements for production-floor ATE and laboratory instrumentation across diverse operating environments.

Design Notes
The EPF6024ATI144-1N requires both VCCINT (core 3.3 V) and VCCIO1-VCCIO4 (I/O bank 3.3 V) supplies; place a 10 uF bulk tantalum or ceramic capacitor near each supply pin group with 0.1 uF ceramic decoupling within 5 mm of each VCC pin. Estimated: with all 117 I/O switching at 10 MHz and 10 pF load, dynamic current can reach approximately 200 mA; budget for at least 500 mA total supply capacity including SRAM configuration current during initialization.
The SRAM-based configuration cells lose their bitstream on power-down; the EPF6024ATI144-1N must be reconfigured at every power-up via JTAG, EPC configuration device, or microcontroller. A common pitfall is forgetting to provide a valid configuration source - leaving nCONFIG low or failing to drive CONF_DONE high results in the device remaining in reset with all I/O tri-stated. Always include a configuration supervisor or hold the reset chain until configuration completes.
The TQFP-144 package has a 0.500 mm pitch requiring careful PCB layout: use 0.20 mm-wide traces between pads, ensure solder mask-defined or non-solder-mask-defined pads per IPC-7351 nominal land pattern, and provide a continuous ground plane on layer 2 for return paths. Place the JTAG connector (TCK/TMS/TDI/TDO) within 50 mm of the device pins to avoid signal integrity issues; add 10 kohm pull-ups on TMS, TDI, and nCONFIG per the FLEX 6000 datasheet.
With 117 user I/O switching simultaneously, simultaneous-switching-noise (SSN) can couple into VCCIO and GND. Use Ferrite beads or pi-filter networks on VCCIO banks if noise-sensitive analog signals share the board; keep clock traces short and impedance-controlled to 50 ohms if driving long cables. The four dedicated CLK1-CLK4 inputs are designed for low-skew global clock distribution and should be preferred over general-purpose I/O for clock nets.
