EPF8636AQC160-3

The EPF8636AQC160-3 is a FLEX 8000 family field-programmable gate array in a 160-pin BQFP package designed for mid-density programmable logic applications. It provides a register-rich architecture with 504 logic elements and 63 logic array blocks to implement control, interfacing, and moderate data-path functions with a high-pin-count I/O footprint.

This device targets system designs that require flexible I/O, in-circuit reconfigurability and board-level testability while operating from a 4.75 V to 5.25 V supply in commercial temperature environments (0 °C to 70 °C).

Key Features

• Core Architecture  504 logic elements and 63 logic array blocks offer a compact LUT-and-register based fabric suitable for control logic, bus glue, and moderate datapath tasks.
• I/O Capacity & Flexibility  Up to 118 user I/O pins allow integration of multiple buses and peripherals; the FLEX 8000 family supports MultiVolt™ I/O behavior enabling core operation at 5.0 V with I/O compatibility for 5.0 V and 3.3 V logic levels.
• Configuration & Test  Supports in-circuit reconfigurability via external configuration devices or an intelligent controller and includes JTAG boundary-scan test circuitry for board-level test and debug.
• Interconnect & Arithmetic Support  FastTrack® continuous routing structure with dedicated carry and cascade chains accelerates implementation of adders, counters, comparators and high‑fan‑in logic constructs.
• System-Level Features  Designed for 5.0‑V operation; devices in the family include features such as programmable output slew-rate control and tri‑state emulation for internal nets.
• Power & Supply  Operates from a 4.75 V to 5.25 V supply and offers low-power standby behavior (typical standby current specification noted in family data).
• Package & Mounting  Surface-mount 160-BQFP package; supplier device package listed as 160‑PQFP (28×28) for board-level footprint reference. Commercial-grade operating temperature: 0 °C to 70 °C.
• Compliance & Environmental  RoHS compliant; family data notes compliance with PCI Local Bus Specification (Revision 2.2) for 5.0‑V operation where applicable.

Typical Applications

• Bus Interfaces  Use the EPF8636AQC160-3 to implement multi‑bus bridges and bus glue logic, taking advantage of its high I/O count and flexible routing.
• Peripheral & TTL Integration  Ideal for interfacing TTL peripherals and legacy logic where mixed 5.0 V / 3.3 V signaling and plentiful I/O are required.
• Control & High-Speed Controllers  Suitable for custom control logic and board-level controllers that require registers, predictable routing, and dedicated arithmetic chains.
• Coprocessor & Glue Logic  Fits designs that need custom coprocessing blocks or glue logic between processors and peripherals, leveraging the device’s register resources and dedicated fast-carry paths.
• DSP & Data Manipulation  Provides register-rich resources and routing to support moderate DSP tasks, wide-data-path manipulation and data transformation functions.

Unique Advantages

• Mid-density integration  504 logic elements and 63 LABs provide a balanced logic density for designs that need more capability than small CPLDs without moving to higher-density FPGAs.
• Flexible mixed-voltage I/O  MultiVolt I/O compatibility simplifies integration with 5.0 V and 3.3 V peripherals while maintaining a 5.0 V core supply.
• Board-level testability  JTAG boundary-scan support reduces debug time and simplifies manufacturing test flows.
• Fast, predictable routing  FastTrack continuous interconnect and dedicated arithmetic chains reduce timing unpredictability and help meet deterministic timing for control and bus logic.
• Reconfigurability  In-circuit reconfigurability enables field updates and design iteration without board replacement.
• RoHS compliant  Meets environmental compliance requirements for modern assembly processes.
