Key Features

• Core Capacity & Logic: Approximately 500,000 equivalent system gates and 8,064 logic elements provide substantial logic density for complex designs.
• Embedded Memory & FIFOs: Approximately 73,728 total RAM bits with embedded FIFO control logic and variable-aspect 4,608‑bit RAM blocks for width and depth configurability.
• High Performance: Family-level performance characteristics include 350+ MHz system performance and 500+ MHz internal performance, supporting demanding timing requirements.
• Clocking & PLLs: Segmentable clock resources with embedded PLLs (14–200 MHz input range) and frequency synthesis capabilities up to 1 GHz enable flexible clock management.
• Flexible I/O Standards: 336 user I/Os with bank‑selectable, mixed‑voltage operation (1.5V, 1.8V, 2.5V, 3.3V) and support for single‑ended and differential standards including LVDS and LVPECL; 700 Mb/s LVDS capable I/Os.
• Nonvolatile, Secure Programming: Antifuse programming technology with FuseLock™ protection to guard against reverse engineering and design theft.
• Package & Mounting: 676‑BGA (676‑FBGA, 27 × 27) package, surface‑mount construction for high‑density PCB integration.
• Power & Temperature: Core supply range 1.425 V to 1.575 V and qualified for military grade operating temperatures from −55 °C to 125 °C.
• Standards & Testability: Boundary‑scan testing compliant with IEEE 1149.1 (JTAG) and unique in‑system diagnostic and debug capability via Microchip Silicon Explorer II.
• Environmental Compliance: RoHS‑compliant.

Typical Applications

• Defense and Aerospace Systems: Military grade temperature range and antifuse nonvolatile programming make the AX500‑FG676M suitable for mission‑critical avionics and defense logic functions.
• High‑Performance Signal Processing: High internal and system performance, combined with large logic capacity and embedded FIFOs, supports digital signal processing and data‑path acceleration.
• Secure, Custom Logic Implementations: FuseLock and antifuse programming protect intellectual property for secure control, encryption, or proprietary state machines.
• High‑Speed Interface Control: LVDS‑capable I/Os and bank‑selectable mixed‑voltage support enable implementation of high‑speed serial interfaces and multi‑standard bridging.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Antifuse technology eliminates the need for external configuration memory and supports immediate post‑power functionality.
• Design Security: FuseLock programming protects against reverse engineering and unauthorized reads of the programmed design.
• High Logic Density: 8,064 logic elements and roughly 500,000 equivalent gates allow consolidation of complex functions into a single device to reduce system BOM.
• Integrated Memory and FIFO Control: On‑chip SRAM and programmable FIFO logic simplify data buffering and interface staging without external memory.
• Flexible I/O and Clocking: Bank‑selectable mixed‑voltage I/Os, differential standard support and embedded PLLs enable versatile interface and clocking architectures.
• Mil‑Grade Reliability: Specified operating range from −55 °C to 125 °C and military grade classification for robust performance in harsh environments.
