MPN: EPF10K10LI84-4N ✗ Cuối đờiEPF10K10LI84-4N Tóm tắt
An FPGA (Field Programmable Gate Array) is a type of programmable logic device whose internal logic cells, interconnect, and I/O are configured by the user after manufacture. Within the broader hierarchy, FPGAs sit alongside CPLDs in the PLD family, and they extend the concept by offering high gate counts, block RAM, and embedded multiplier/DSP blocks. FPGAs are commonly used to prototype ASICs, implement glue logic, drive high-speed parallel interfaces, and accelerate data-path computation in telecommunications, industrial automation, test equipment, and legacy embedded designs.
Key features of the EPF10K10LI84-4N include 72 logic array blocks (LABs) of 8 logic elements each, 3 embedded array blocks (EABs) providing 6144 RAM bits, and 59 user I/O pins. The device supports in-system programmability via Altera's MAX+PLUS II or Quartus design tools using SRAM configuration, and it can be reconfigured in-circuit for design iterations or field upgrades.
Architecturally, the FLEX 10K fabric provides continuous, fast interconnect channels that wire any logic element to any other, with predictable timing well-suited for synchronous state machines, register-rich glue logic, and pipelined datapaths. The 0.42 µm process yields robust 5 V I/O tolerance, which simplifies interfacing to legacy TTL logic commonly found in industrial controllers, instrumentation, and aerospace subsystems.
Typical applications of the EPF10K10LI84-4N include industrial control boards, telecommunications glue logic, legacy instrumentation front-ends, custom bus bridges, and prototyping platforms for ASIC verification. Designers commonly pair the FPGA with EPROM/Flash configuration memories and 5 V bus transceivers. When designing with this part, note that it is not pin-compatible with later 3.3 V FLEX 10KA devices - verify any cross-reference carefully against footprint and voltage.

Ứng dụng tiêu biểu
EPF10K10LI84-4N phù hợp cho 6 Áp dụngs: Industrial Control Logic Replacement, Telecommunications Glue Logic, Legacy Instrumentation Front-End, ASIC Prototyping Platform, Custom Bus Bridge / Protocol Converter, Aerospace / Defense Legacy Avionics.
Industrial Control Logic Replacement
The EPF10K10LI84-4N replaces obsolete discrete TTL or 74-series glue logic on legacy industrial PLC and motor-controller boards. Its 576 logic elements and 72 LABs provide enough capacity to consolidate dozens of SSI/MSI packages into a single reprogrammable device, simplifying board rework and reducing parts count. The 5 V supply tolerance matches the legacy bus rails directly without level shifters, and the 84-pin PLCC footprint drops into existing sockets for direct board replacement. Engineers can store multiple logic configurations in the configuration EPROM and switch personality in the field, enabling a single board SKU to serve multiple machine variants.
Được đề xuất
Telecommunications Glue Logic
The EPF10K10LI84-4N serves as bus-bridging and timing glue logic in telecommunications backplane designs where it interfaces legacy T1/E1 framers, ECL/TTL converters, and protocol converters. Its 59 user I/O pins provide ample connectivity for multi-bus bridging, while the 3 embedded array blocks (EABs) deliver 6,144 bits of RAM for small FIFO buffers and lookup tables. The 5 V I/O tolerance matches existing backplane logic levels directly, eliminating the level-shifting components required by modern 3.3 V FPGAs.
Được đề xuất
Legacy Instrumentation Front-End
The EPF10K10LI84-4N is well suited to legacy instrumentation front-ends that require programmable timing, channel-selection logic, and DSP preprocessing for analog-to-digital converter arrays. The 125 MHz internal performance supports real-time sample-rate conversion, while the 5 V tolerance accepts TTL-level trigger and clock signals directly from front-end analog circuitry. The embedded array blocks can implement small coefficient ROM tables for digital filtering, eliminating external memory ICs and reducing board complexity.
Được đề xuất
ASIC Prototyping Platform
Designers use the EPF10K10LI84-4N as an FPGA prototype for ASIC designs targeting gate counts up to 10,000 gates. The FLEX 10K architecture's LAB-based fabric maps efficiently from RTL synthesis, and 5 V I/O tolerance enables prototyping of ASICs that will eventually be fabricated in 5 V or mixed-voltage processes. Real-time in-circuit emulation allows design verification at full system speed before committing to NRE charges for silicon fabrication.
Được đề xuất
Custom Bus Bridge / Protocol Converter
The EPF10K10LI84-4N implements custom bus bridges between legacy parallel buses (ISA, PC/104, VME) and modern peripherals, translating timing and protocol in real time. With 576 logic elements and 59 I/O pins, a single device handles address decoding, wait-state generation, and protocol translation for multi-master systems. The 5 V tolerance matches legacy bus voltages directly, while the SRAM-based configuration allows firmware updates over JTAG for evolving bridging requirements.
Được đề xuất
Aerospace / Defense Legacy Avionics
The EPF10K10LI84-4N supports legacy avionics and defense subsystem upgrades where form-fit-function replacement of original 5 V FPGAs is mandatory. Its mature 0.42 µm CMOS process has long-term reliability data, and the 84-pin PLCC is compatible with established avionics socket infrastructure. The device's ability to be reconfigured in-system supports avionics software updates without board removal, and its 5 V tolerance matches the ARINC 429 and MIL-STD-1553 bus levels used in legacy aircraft.

Ghi chú thiết kế
The EPF10K10LI84-4N requires a stable 5 V supply on both VCCINT (core) and VCCIO1-VCCIO7 (I/O banks). Per Altera FLEX 10K datasheet recommendations, decouple each VCC pin with a 0.1 µF ceramic capacitor placed within 5 mm of the package pin, plus a bulk 100 µF electrolytic capacitor on the supply rail. Power sequencing is not mandatory since the device is single-rail, but the nCONFIG pin must be held low during power-up ramp and released after VCC reaches 4.75 V to ensure clean configuration.
Place the configuration memory (typically EPC2LC20N) within 50 mm of the EPF10K10LI84-4N DATA0/DCLK/nCONFIG/nSTATUS pins to minimize signal integrity issues. Use parallel termination on the DCLK line if the configuration memory is more than 25 mm away. Route all configuration signals over a continuous ground plane and avoid routing them parallel to high-speed switching signals for more than 10 mm to prevent crosstalk into the configuration chain.
Do NOT substitute EPF10K10LI84-4N with EPF10K10AQC208-3N or other 3.3 V FLEX 10KA variants - the supply voltage differs (3.3 V vs 5 V) and the package differs (208-pin QFP vs 84-pin PLCC). The 'A' in the part number denotes the 3.3 V FLEX 10KA family. Using a 3.3 V part on a 5 V board will damage the device instantly. Always cross-reference by full part number including package code.
Thông tin tuân thủ
RoHS/lead-free status could not be confirmed from the provided web data. The FLEX 10K family predates RoHS mandates (2006), so original parts are likely non-compliant; lead-free variants may exist from later production runs but are not documented in the provided sources.
