Key Features

• Core Performance — Approximately 250,000 equivalent system gates and 4,224 logic elements provide the programmable logic capacity required for mid-density designs.
• Embedded Memory & FIFOs — Approximately 55 kbits (55,296 bits) of embedded SRAM/FIFO with programmable FIFO control logic and variable-aspect RAM blocks for flexible data buffering and storage.
• I/O and Interfaces — 115 user I/Os with support for high-speed differential signaling; datasheet cites LVDS-capable I/Os up to 700 Mb/s and a variety of multi-standard I/O options at mixed voltages.
• Clocking & PLLs — Segmentable clock resources and embedded PLLs with a 14–200 MHz input range and frequency synthesis capabilities up to 1 GHz enable robust timing architectures.
• Nonvolatile Antifuse Technology — Single-chip antifuse programming delivers a nonvolatile configuration and includes FuseLock programming technology for design security and protection against reverse engineering.
• Power — Core supply range of 1.425 V to 1.575 V (nominal 1.5 V) to support low-power core operation.
• Package & Mounting — 208-BFQFP package, surface-mount mounting; supplier device package listed as 208-PQFP (28×28).
• Operating Range & Grade — Military grade with operating temperature range from −55 °C to 125 °C and RoHS-compliant status.

Typical Applications

• Military and Defense Systems — Military-grade temperature range and antifuse nonvolatile configuration suit secure, rugged embedded systems requiring long-term reliability.
• High-Speed Communications — LVDS-capable I/Os and on-chip PLLs support high-throughput serial links and clock synthesis for communications front-ends.
• Embedded Signal Processing — Mid-density logic capacity, dedicated RAM/FIFO blocks, and deterministic timing make the device suitable for buffering, filtering, and protocol processing tasks.
• Secure and IP-Sensitive Designs — Antifuse programming combined with FuseLock technology provides a hardware-based approach to protect intellectual property and prevent reverse engineering.

Unique Advantages

• Single-Chip Nonvolatile Solution: Antifuse architecture eliminates the need for external configuration memory and stores the programmed design on-chip.
• High Deterministic Performance: Documented system and internal performance metrics (350+ MHz system, 500+ MHz internal) and segmentable clocks enable tightly controlled timing for critical paths.
• Integrated Memory and FIFO Support: Embedded SRAM blocks with programmable FIFO logic reduce external memory requirements for many buffering and stream-handling tasks.
• Secure Programming: FuseLock programming technology protects designs from reverse engineering and enhances IP security.
• Wide Thermal and Voltage Operating Range: Military-grade operating temperature (−55 °C to 125 °C) and 1.425–1.575 V core supply support demanding environmental and power conditions.
• Flexible I/O Standards: Bank-selectable and multi-standard I/O support, including high-speed differential signaling, facilitates interoperability across mixed-voltage systems.
