EP1K100FC256-3

The EP1K100FC256-3 is an ACEX-1K family field programmable gate array (FPGA) provided in a 256‑FBGA (17×17) surface-mount package. It combines a logic array and embedded array blocks (EABs) to deliver on-chip memory and general logic resources for system-level integration.

Designed for commercial applications, this device targets system-on-a-programmable-chip (SOPC) integration and communications-oriented designs that require a balance of logic capacity, embedded RAM, and flexible I/O. Key electrical and environmental parameters include a supply range of 2.375 V to 2.625 V and an operating temperature range of 0 °C to 70 °C.

Key Features

• Logic Capacity — 4,992 logic elements (LEs) and an internal equivalent of approximately 257,000 system gates, enabling medium-density programmable logic implementations.
• Embedded Memory — 49,152 total RAM bits implemented across 12 embedded array blocks (EABs); EABs support dual-port operation and up to 16-bit width per block for efficient on-chip data storage and buffering.
• I/O and System Voltage — 186 user I/O pins with MultiVolt I/O capability noted for the ACEX-1K family; device operates with a specified supply range of 2.375 V to 2.625 V and an internal 2.5‑V supply operation (per family datasheet).
• Package and Mounting — 256‑pin FineLine BGA (256‑FBGA, 17×17) in a surface-mount package, suitable for compact board layouts.
• Built-in Test and Configuration — JTAG boundary-scan test (IEEE 1149.1) and in-circuit reconfigurability via external configuration devices, intelligent controller, or JTAG port (family-level features).
• Dedicated Arithmetic and Routing — Family architecture includes dedicated carry and cascade chains and FastTrack interconnect for predictable routing delays and efficient implementation of adders, counters, and high-fan-in logic (per ACEX-1K documentation).
• Commercial Grade and Compliance — Commercial-grade device with RoHS compliance; specified operating range 0 °C to 70 °C.

Typical Applications

• Communications Interfaces — Implement protocol bridging, packet buffering, or interface glue logic where on-chip RAM and moderate logic density streamline board-level complexity.
• System Integration / SOPC — Integrate memory-mapped peripherals, custom logic blocks, and on-chip buffering to consolidate subsystems into a single programmable device.
• Embedded Control and Glue Logic — Replace multiple discrete components with programmable logic for control sequencing, bus interfacing, and timing-critical glue functions.
• Memory-Intensive Functions — Use the 12 EABs and dual-port capability for FIFOs, small on-chip data stores, and buffering in designs that require local RAM.

Unique Advantages

• Balanced Integration: 4,992 logic elements combined with ~49kbits of embedded RAM reduce the need for external components and simplify board-level design.
• Flexible I/O: Family-level MultiVolt I/O support and 186 user I/Os allow interfacing with a variety of voltage domains and peripheral devices.
• Design Predictability: FastTrack interconnect and dedicated carry/cascade chains provide predictable routing and efficient implementation of arithmetic and high-fan-in logic.
• In-system Reconfigurability: JTAG and in-circuit configuration options enable field updates and iterative development without hardware changes.
• Compact Packaging: 256‑FBGA (17×17) surface-mount package supports high-density board layouts while keeping device count and BOM complexity low.
