EPF6024ATC44-1 概述

The Altera (Intel) EPF6024ATC44-1 is a member of the FLEX 6000 programmable logic device family, providing approximately 24,000 typical gates in a 44-pin TQFP (TC44) package. As a member of the FLEX 6000 family, it offers SRAM-based configuration with 1,960 logic elements and 117 I/O pins allocated to user I/O. The device operates from a 3.3V core supply with multi-volt I/O support, suitable for glue-logic, control, and bridge functions in industrial systems.

A Field-Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs), programmable interconnects, and programmable I/O cells that can be re-programmed to implement arbitrary digital logic. FPGAs sit above CPLDs in the programmable logic hierarchy and below custom ASICs in terms of density and performance-per-watt. The FLEX 6000 family specifically targets cost-sensitive glue-logic applications, using Altera's patented Logic Element (LE) architecture with embedded look-up tables (LUTs), a fast continuous interconnect, and a per-pin I/O element (IOE) with registered input, output, or bidirectional mode.

Key features of the EPF6024ATC44-1 include 24,000 typical gates / 1,960 logic elements, 117 user I/O pins, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface, and 3.3V core operation with selectable I/O voltage standards. The TC44 package is a 44-lead Thin Quad Flat Pack suitable for surface-mount assembly with moderate pin-count requirements.

The FLEX 6000 family architecture uses a four-input LUT per logic element, with a dedicated carry chain for fast adders and a cascade chain for wide fan-in functions. Each IOE contains a tri-state buffer, output enable control, and programmable slew-rate, making the family well suited to bus interfacing. MultiVolt I/O pads allow the device to interface directly with 5.0V, 3.3V, and 2.5V peripherals without external level shifters.

Typical applications include industrial control logic, bus bridging between legacy 5V systems and modern 3.3V processors, glue-logic replacement for discrete 74-series TTL, and low-volume custom state machines. The 117 I/O count (with the 144-pin package variant) also supports moderate-density data-pipeline functions.

When designing with this device, ensure proper decoupling (100 nF + 10 uF minimum) within 5 mm of each supply pin, and verify that the configuration source (EPC or JTAG) matches the production flow. The FLEX 6000 family is in production legacy status - designers targeting new designs should evaluate Cyclone IV/V or MAX series for current production equivalents.

This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet - giving engineers and procurement specialists a faster path to BOM validation and supply-chain decision-making.

🏭

Industrial Glue Logic Replacement

The EPF6024ATC44-1's 1,960 logic elements and 117-user-I/O capability (in the 144-pin variant) make it ideal for replacing discrete 74-series TTL and CMOS glue-logic on legacy industrial controllers. Engineers typically consolidate 5-15 discrete SSI/MSI packages into a single FPGA, reducing PCB area by 60-70% and BOM cost by 30-50%. The 3.3V core with MultiVolt I/O allows direct interface with 5V legacy peripherals without external level shifters. The TC44 44-pin TQFP package exposes a moderate I/O count suitable for control-board signal aggregation. Programming via JTAG or EPC configuration devices simplifies field updates. The device's commercial 0-70C temperature grade suits factory-floor enclosures.

Bus Bridge Between 5V and 3.3V Domains

The EPF6024ATC44-1 supports MultiVolt I/O, allowing its VCCIO rail to be configured for 5.0V TTL or 3.3V LVTTL signalling while the core runs at 3.3V. This makes the FPGA ideal as a bidirectional bus bridge between legacy 5V microcontrollers (8051, 68HC11) and modern 3.3V ARM processors. Engineers can implement 8/16/32-bit wide bus translation with timing-critical handshakes in firmware-equivalent hardware. The 1,960 logic elements provide ample headroom for state machines plus protocol converters. The TC44 package pinout supports up to 117 user I/O (in larger variants), sufficient for multi-channel bus isolation. Pin-compatible with the EPF6024ATC44-2/3 family for speed-grade scaling.

Custom State Machine Controller

For low-to-medium-volume products that cannot justify an ASIC NRE, the EPF6024ATC44-1 implements arbitrary state machines, sequence generators, and protocol handlers in a single chip. With 1,960 logic elements (~24,000 gates) and a fast continuous interconnect fabric, designers can typically encode state machines with 64-256 states plus associated datapath logic. Common applications include motor-control sequencers, sensor-fusion pre-processors, and timing-critical arbitration units. The TC44 package's modest pin count suits state machines with 10-20 inputs and outputs. JTAG boundary scan per IEEE 1149.1 enables in-system test and verification - critical for medical and aerospace state machines.

Legacy Board Replacement / EOL Substitution

The EPF6024ATC44-1 is in NRND status, but its established footprint and mature Altera Quartus II tool flow make it ideal as a form-fit-function replacement on discontinued legacy boards. Aerospace, defence, and industrial systems designed in the late 1990s through early 2000s often require exact part substitution to preserve FCC/CE certifications. Engineers replace obsolete FLEX 8000 or early FLEX 6000 with the EPF6024ATC44-1 to extend system lifecycle 10-15 years. The TC44 package allows drop-in PCB placement using the same land pattern. Configuration bitstreams generated by legacy MAX+PLUS II or Quartus tools remain forward-compatible.

Data Pipeline / Pre-Processing Buffer

The EPF6024ATC44-1 with approximately 4 Kbits of embedded RAM can implement small FIFO buffers, packet parsers, and protocol pre-processors for high-speed serial or parallel data streams. In telecommunications line cards, the device is used for HDLC framing, ATM cell delineation, and SONET overhead processing. With 1,960 logic elements the FPGA handles data widths up to 32 bits at moderate clock rates (50-80 MHz in -1 speed grade). The TC44 44-pin package is appropriate for daughter-card pre-processor functions where I/O count is moderate. JTAG-based in-system reconfiguration enables field upgrades for evolving protocols.

Test & Measurement Instrumentation Logic

The EPF6024ATC44-1 is widely used in bench-top test equipment as a flexible pattern generator, protocol decoder, or timing generator. Its SRAM-based configuration allows engineers to load new test sequences in seconds via JTAG, eliminating the lead times associated with ROM/PAL-based designs. The 1,960 logic elements can encode complex pattern sequences, PRBS generators, or arbitrary waveform trigger logic. The 3.3V core with selectable I/O standards supports direct connection to TTL-level test points on legacy DUTs. The TC44 commercial temperature grade is adequate for laboratory environments. The -1 speed grade is sufficient for typical 50 MHz instrument clocks.

The EPF6024ATC44-1 remains valid only for legacy board replacements.

Where can I download the EPF6024ATC44-1 datasheet PDF?

The EPF6024ATC44-1 datasheet can be downloaded from Altera/Intel's FLEX 6000 device family datasheet (covers all package variants including TC44) at the legacy Altera support portal. Third-party datasheet mirrors also host the file at abc-semi.com and alldatasheet.com - both confirm the part is the same 24K-gate FLEX 6000 FPGA in a 44-pin TQFP.

Where can I find the EPF6024ATC44-1 pinout?

The pinout for the EPF6024ATC44-1 is published in the FLEX 6000 Device Family Data Sheet. The 44-pin TQFP pin assignment dedicates 4 pins to GND, 4 pins to VCCINT (3.3V), 4 pins to VCCIO, and the remainder to user I/O, JTAG (TCK/TMS/TDO/TDI), and configuration signals (nCONFIG/nSTATUS/CONF_DONE/MSEL). Full pin-by-pin assignments are in the datasheet section titled 'Pin Information'.

What is the best Cyclone equivalent for the EPF6024ATC44-1?

The Cyclone equivalent for the EPF6024ATC44-1 in terms of logic density is the EP1C3 (Cyclone I) or EP4CE6 (Cyclone IV E) - both provide 2,910-6,272 logic elements in modern packages. However, neither is footprint-compatible with TC44; PCB redesign is required. The MAX II CPLD EPM240T100 is the closest modern non-FPGA replacement in a similar pin-count TQFP package.

选型指南

Choose the EPF6024ATC44-1 when you need a moderate-density (24,000 gates / 1,960 logic elements) SRAM-based FPGA in a compact 44-pin TQFP for industrial glue-logic, bus bridging, or state-machine functions where the commercial 0-70C temperature grade is acceptable. Choose the EPF6024ATC44-2 or EPF6024ATC44-3 instead if your timing budget is tight - the higher speed grades (faster propagation delay) come at modest 10-15% / 20-30% cost premiums in the same TC44 footprint. Choose the EPF6024ATC144-1 if you need more than 40 user I/O - the 144-pin LQFP exposes the full 117 I/O count. For new designs, evaluate the EPM240T100 MAX II CPLD as a non-volatile, lower-power alternative in a similar pin-count package.

设计说明

The EPF6024ATC44-1 requires both VCCINT (3.3V core) and VCCIO (3.3V/5.0V/2.5V I/O) rails. Decoupling must include a 100 nF ceramic capacitor within 5 mm of every VCCINT and VCCIO pin, plus at least one 10 uF bulk capacitor per supply rail. Power-on ramp should be monotonic; if VCCINT rises before VCCIO, the I/O pads may drive into contention. Estimated: ICCINT typical ~50 mA and ICCIO ~10-30 mA depending on I/O toggle rate - verify against actual design activity factor.

Place the JTAG chain (TCK/TMS/TDI/TDO) on dedicated PCB traces with 4.7 kohm pull-ups on TCK/TMS/TDI per IEEE 1149.1. Series-termination resistors of 33-68 ohm on high-speed clock outputs reduce ringing. Route configuration signals (nCONFIG, nSTATUS, CONF_DONE) away from switching I/O to avoid coupling-induced configuration failures. The TC44 44-pin TQFP package has an exposed thermal pad that should be soldered to a thermal relief pad tied to GND for improved heat dissipation.

Do not leave MSEL pins floating - strap them to VCCINT or GND to select the configuration mode (EPC1, EPC2, JTAG). The nCONFIG signal must see a clean 0-to-1 transition after VCCINT stabilises; a slow rise can latch the device into an indeterminate configuration state. During JTAG programming, ensure the configuration file matches the device ID - programming the wrong bitstream can corrupt internal configuration RAM. Estimated: configuration time is ~50 ms typical; budget at least 100 ms before user-mode assertion.
