AX500-FGG676

The AX500-FGG676 is an Axcelerator antifuse-based FPGA offering a balance of mid-range logic capacity and high-speed I/O resources. Built on the AX architecture, it provides on-chip SRAM/FIFO, segmentable clocking and PLL resources suited for applications that require deterministic timing and embedded data buffering.

Designed for commercial-grade systems, this device combines 8064 logic elements, 73,728 bits of embedded RAM/FIFO, and 336 user I/Os in a 676-ball BGA package with a 1.425–1.575 V core supply and a 0 °C to 70 °C operating range.

Key Features

• Logic Capacity — 8064 logic elements and 500,000 equivalent system gates provide mid-range programmable logic for custom control, signal processing and glue-logic implementations.
• On-chip Memory and FIFOs — 73,728 bits of embedded SRAM with programmable FIFO control logic enable local buffering and efficient data flow management.
• I/O Resources — 336 user I/Os across bank-selectable I/O banks with multi-standard support, including LVDS and other single-ended/differential standards listed in the family feature set.
• High-Speed Performance — Family-level performance characteristics include 350+ MHz system performance and internal performance up to 500+ MHz, and LVDS-capable I/Os rated to 700 Mb/s (as specified for the Axcelerator family).
• Clocking and PLLs — Segmentable clock resources and embedded PLLs support clock management and frequency synthesis across the device.
• Nonvolatile Antifuse Technology — Single-chip, nonvolatile antifuse programming with FuseLock™ programming protection provides design security and resistance to reverse engineering.
• Power and Temperature — Core supply range of 1.425 V to 1.575 V (nominal 1.5 V) and commercial operating temperature 0 °C to 70 °C.
• Package and Mounting — Surface-mount 676-ball BGA (supplier package: 676-FBGA, 27 × 27) for compact board-level integration.
• Standards and Testability — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic capability through Microchip tools referenced in the family documentation.
• Environmental — RoHS-compliant.

Typical Applications

• High-speed data interfaces — LVDS-capable I/Os and bank-selectable standards support implementation of high-speed serial and parallel links requiring deterministic buffering.
• Embedded buffering and packet handling — On-chip SRAM blocks with embedded FIFO control logic enable localized data flow management for real-time packet buffering and staging.
• Custom digital controllers — 8064 logic elements and segmented clock resources make the device suitable for implementing custom state machines, control logic and signal preprocessing.
• Clock generation and timing-sensitive designs — Integrated PLLs and segmentable clocks support designs that require precise frequency synthesis and controlled timing domains.

Unique Advantages

• Single-chip nonvolatile solution: Antifuse-based programming eliminates the need for external configuration memory and delivers persistent configuration at power-up.
• Deterministic timing and diagnostics: Segmentable clocks, embedded PLLs and documented in-system diagnostic capabilities enable predictable timing behavior and board-level debugging.
• Flexible I/O mix: Bank-selectable I/O standards and programmable drive/slew characteristics simplify interfacing with mixed-voltage peripherals and high-speed links.
• Integrated memory with FIFO control: On-chip SRAM blocks and programmable embedded FIFO logic reduce external memory dependencies for data buffering tasks.
• Security-oriented programming: FuseLock™ programming technology offers protection against reverse engineering and design theft as described in the family documentation.
• Compact integration: 676-ball BGA surface-mount package provides a dense footprint for space-constrained board designs.

Why Choose AX500-FGG676?
