EP1K100QC208-1

The EP1K100QC208-1 is an ACEX‑1K family FPGA offering programmable logic and embedded memory for system-level integration. It combines approximately 4,992 logic elements and about 49,152 bits of on-chip RAM with dedicated architectural features suited for SOPC-style integration and communications-focused designs.

This device is a commercial‑grade, surface‑mount FPGA in a 208‑BFQFP package that supports a 2.375–2.625 V supply and operates across a 0 °C to 70 °C temperature range, providing a compact, reconfigurable building block for mid-density digital designs.

Key Features

• Core Capacity  Approximately 4,992 logic elements (LEs) and a maximum system gate equivalence of 257,000 for implementing moderate-complexity logic and control functions.
• Embedded Memory  Approximately 49,152 bits of on-chip RAM with multiple embedded array blocks (EABs) that support efficient dual-port memory configurations.
• I/O and Voltage  147 user I/O pins with MultiVolt I/O capability described in the family datasheet; the device operates with an internal 2.5 V supply and requires an external supply in the 2.375 V to 2.625 V range.
• Package & Mounting  208‑BFQFP (supplier package: 208‑PQFP 28×28), surface‑mount mounting type for compact board layouts.
• System and Configuration  Supports in-circuit reconfigurability (ICR) and includes JTAG boundary-scan test (IEEE 1149.1) circuitry available without consuming device logic.
• Clocking & Performance Features  Built-in low-skew clock distribution trees, dedicated carry and cascade chains for arithmetic and high‑fan‑in logic, and options for ClockLock and ClockBoost to manage clock delay and skew (as described in the ACEX‑1K family documentation).
• Grade & Temperature  Commercial grade, specified for operation from 0 °C to 70 °C.
• Standards & Interoperability  Family-level documentation notes PCI Local Bus Specification compliance options for certain speed grades and MultiVolt I/O compatibility with 2.5 V, 3.3 V, and 5.0 V devices (refer to family datasheet for details).

Typical Applications

• Communications Interfaces  Use for protocol bridging, packet buffering, and mid‑density datapath logic where embedded dual‑port RAM and deterministic interconnect are required.
• SOPC/System Integration  Implement custom system‑on‑chip functions and glue logic to consolidate multiple discrete components into a single programmable device.
• Control and Timing  Realize timing-critical control logic and arithmetic functions using dedicated carry/cascade chains and low‑skew clocking resources.
• Prototyping and Reconfigurable Logic  Ideal for iterative development where in‑circuit reconfigurability and JTAG boundary-scan support streamline testing and updates.

Unique Advantages

• Balanced Logic and Memory  Combines nearly 5,000 logic elements with about 49,152 bits of embedded RAM to support mixed logic and buffering needs without external memory in many designs.
• Flexible I/O and Voltage Support  MultiVolt I/O options (family-level) and a defined external supply range (2.375–2.625 V) enable interfacing with a variety of system voltages.
• Reconfigurability and Testability  In-circuit reconfigurability and integrated JTAG boundary-scan provide proven methods for updates and board-level test without consuming user logic.
• Compact Packaging  208‑pin BFQFP surface-mount package provides a space-efficient solution for board designs requiring moderate I/O count and logic density.
• Architectural Support for Arithmetic and High-Fan-In Logic  Dedicated carry and cascade chains simplify implementation of fast adders, counters, and high fan-in functions, improving performance for common digital building blocks.
