EPF6024ATC44-1 Visão geral
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.

Aplicações típicas
EPF6024ATC44-1 é adequado para 6 aplicaçãos: Industrial Glue Logic Replacement, Bus Bridge Between 5V and 3.3V Domains, Custom State Machine Controller, Legacy Board Replacement / EOL Substitution, Data Pipeline / Pre-Processing Buffer, Test & Measurement Instrumentation Logic.
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.

Notas de projeto
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.
Informações de conformidade
Compliance information not explicitly provided in the verified web data. The FLEX 6000 family was originally released in the late 1990s when RoHS compliance was not yet required; later production batches may include lead-free / RoHS-compliant variants - verify by date code with the distributor before purchase.
