EPF8636ALC84-4N Обзор
A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and programmable I/O cells. The FLEX 8000 family sits at the intersection of high density and low cost, scaling from 2,500 usable gates up to 16,000 usable gates with up to 1,500 registers, and is positioned in the broader taxonomy as FPGA → programmable logic → logic IC → integrated circuit. The architecture is configured at power-up by loading SRAM bitstream from an external EPROM or an Altera serial configuration device (EPC1, EPC1064, EPC1213, or EPC1441), giving every device unlimited in-circuit reconfigurability (ICR).
Key features include 63 Logic Array Blocks (LABs), 504 logic elements, 68 I/O pins operating at 5.0 V, in-system reconfigurability via serial configuration devices, and MultiVolt I/O support that allows interface with mixed-voltage systems. The 84-pin PLCC package provides through-hole-friendly J-leads compatible with standard sockets and rework, making the part attractive for legacy industrial designs and prototyping. The device supports JTAG-based boundary-scan testing per IEEE 1149.1.
The FLEX 8000 architecture combines fine-grained logic elements with FastTrack interconnect, delivering deterministic timing with pin-to-pin delays suitable for glue logic, bus interfacing, and state-machine replacement. Up to six global clock networks and dedicated carry chains accelerate arithmetic functions, while embedded memory blocks provide efficient FIFO and small-RAM implementations. Configuration time is sub-second, and bitstream compression options reduce external storage requirements.
Typical applications include industrial control glue logic, legacy peripheral bus bridging, telecom line-card interface logic, military and aerospace subsystems (with separate screening), and prototyping platforms where PLCC-socketed parts simplify device swap. The combination of high pin count and in-system reconfigurability makes the EPF8636ALC84-4N well suited for designs that must adapt to evolving standards or field firmware updates.
When designing with this device, ensure your configuration PROM (EPC1, EPC1064, EPC1213, or EPC1441) is sized for the uncompressed bitstream unless you enable Altera's bitstream compression. Decoupling should follow Altera's application-note recommendations: 0.1 µF at every VCC pin, with bulk tantalum or ceramic on each rail. The 5 V VCCIO requirement means this part cannot drop into a 3.3 V-only system without level shifters.

Типичное применение
EPF8636ALC84-4N подходит для 6 применениеs: Industrial Glue Logic and Bus Bridging, Legacy Telecom Line-Card Interface Logic, Prototyping Platform and Educational FPGA Board, Aerospace and Defense Subsystem Controllers, Test and Measurement Backplane Instrumentation, Automotive and Heavy-Equipment ECU Peripherals.
Industrial Glue Logic and Bus Bridging
The EPF8636ALC84-4N's 6,000 usable gates and 68 user I/Os make it a natural fit for industrial glue-logic replacement, where it consolidates scattered 74-series TTL, PAL/GAL, and small PLDs into a single in-system-reconfigurable device. With 504 logic elements and 63 LABs, the part can replace 30-60 discrete logic packages while adding JTAG boundary-scan for production test. Designers use it to bridge legacy 8/16-bit µC buses (8051, 68k) to modern peripherals, or to implement custom timing/sequencing that no off-the-shelf ASIC provides. The 5 V I/O and 0 °C-70 °C commercial range align with most factory-floor PLC and motor-drive subsystems.
Рекомендуется
Legacy Telecom Line-Card Interface Logic
Telecom line-card and central-office designs of the late 1990s and early 2000s adopted the FLEX 8000 family for its deterministic timing and high I/O count. The EPF8636ALC84-4N is well suited to TDM bus formatting, HDLC framer glue, and serial-to-parallel conversion between E1/T1 framers and backplane ASICs. Its 68 user I/Os comfortably drive 8-bit data buses plus framing/clock/signalling overhead without external bus drivers. The in-system reconfigurability allows field-tariff or protocol upgrades without board removal, a major operational advantage for carriers. Modern replacements (Cyclone IV, MAX V) are not pin-compatible, so PLCC-84 retention keeps existing shelves in service.
Рекомендуется
Prototyping Platform and Educational FPGA Board
Because the 84-pin PLCC J-Lead package is socket-friendly, the EPF8636ALC84-4N is a popular choice for university FPGA laboratories and rapid-prototyping boards where students swap devices for different lab exercises. The 6,000-gate density is enough to demonstrate finite-state machines, multipliers, simple CPUs (e.g., a 16-bit RISC-V subset), UARTs, SPI/I2C controllers, and basic VGA timing. In-system reconfigurability via EPC1/EPC1064 allows the same board to be reused across many lab sessions without reprogramming hardware. Its 5 V tolerance also makes the part tolerant of older lab power supplies.
Рекомендуется
Aerospace and Defense Subsystem Controllers
The FLEX 8000 family has a long heritage in aerospace and defense subsystems where deterministic timing and radiation tolerance screening (when ordered through MIL-PRF-38535 flows) are valued. The EPF8636ALC84-4N in the commercial grade is used in non-flight ground-support equipment, while MIL-screened variants of the same die support flight-control interfaces, mission-computer I/O expansion, and radar signal-conditioning boards. The 68 user I/Os comfortably aggregate sensor buses, MIL-STD-1553 transceivers, and discrete discretes. Designers preserve the PLCC-84 footprint across ruggedized, conduction-cooled chassis.
Рекомендуется
Test and Measurement Backplane Instrumentation
Test-and-measurement equipment such as logic analyzers, protocol exercisers, and ATE fixture controllers historically used FLEX 8000 FPGAs for pattern generation, timing-and-control sequencing, and bus protocol re-mapping. The EPF8636ALC84-4N's 504 logic elements implement 32-64 channel pattern generators with sub-10 ns edge accuracy, while 68 user I/Os drive both the DUT (device-under-test) interface and the instrument's local microcontroller. In-system reconfigurability enables field upgrades as new protocols are supported without returning the instrument. The PLCC-84 socket simplifies calibration swaps.
Рекомендуется
Automotive and Heavy-Equipment ECU Peripherals
While the EPF8636ALC84-4N is commercial-grade (0 °C to 70 °C), its sibling FLEX 8000 devices with industrial screening are used in heavy-equipment ECUs for body controllers, dashboard multiplexing, and sensor aggregation. The 6,000-gate density and 68 I/Os aggregate CAN/LIN fan-out, switch-matrix scanning, and PWM channels. In-system reconfigurability allows OEM software updates over the diagnostic port without ECU replacement. Note: AEC-Q100 qualified parts do not exist in the FLEX 8000 family; for new automotive designs, Cyclone IV or MAX V are the recommended paths.

Заметки по проектированию
The EPF8636ALC84-4N operates at 5.0 V VCC and requires careful decoupling on every supply pin. Place a 0.1 µF ceramic decoupling capacitor as close as possible to each VCC pin (pins 3, 17, 27, 37, 47, 57, 74), and add a 1-10 µF bulk tantalum or ceramic capacitor per supply bank. Estimated: at typical 5 V VCCIO operation with ~50 mA quiescent current, total power dissipation is approximately 250 mW for a quiescent (unconfigured) device; configured device power scales with toggle rate and can reach 1 W. Plan thermal headroom accordingly.
The 84-pin PLCC J-Lead package has a 1.27 mm pitch and is best used with a PLCC-84 socket to simplify configuration swap, factory programming, and field replacement. If socketing is not used, ensure the J-leads are soldered with a profiled reflow or wave-solder cycle and that pad geometry matches the IPC-SM-782 land pattern. Maintain a continuous ground plane beneath the device to minimize ground bounce on the 63 LAB outputs and to provide low-impedance return paths for the 68 user I/Os.
Common pitfalls: (1) selecting the wrong configuration PROM - the EPC1064 stores 64 Kbit and is the minimum, but always verify against your compiled bitstream size; (2) omitting the external 1 kΩ pull-up on nCONFIG and 10 kΩ pull-up on nSTATUS - both pins require pull-ups for proper configuration sequencing; (3) confusing 5 V VCC with 3.3 V VCC - this device does NOT support 3.3 V operation and will be damaged by undervoltage; (4) using the -4 suffix when the -3 timing grade is required - the -4 is faster, so substituting the wrong grade will not fail but timing may close poorly; (5) failing to enable JTAG chain integrity test before deployment.
Place configuration-related components (EPC1064/EPC1441 PROM, JTAG header, nCONFIG pull-up, DCLK series-termination) within 50 mm of the FPGA to avoid signal-integrity issues on the configuration bus. Route CONF_DONE and nSTATUS away from high-frequency switching I/O to prevent false configuration errors. For designs that use MultiVolt I/O interfaces, group 5 V and 3.3 V I/O into separate banks (banks 1-4 on the EPF8636A) and add bus-switch or level-translator ICs at bank boundaries.
Информация о соответствии
