AX1000-1FGG484

The AX1000-1FGG484 is an Axcelerator family Field Programmable Gate Array (FPGA) from Microchip Technology based on the AX antifuse architecture. It delivers a one-million-gate equivalent fabric with on-chip SRAM and embedded FIFO control logic, targeting high-performance, single-chip nonvolatile implementations.

Designed for applications requiring dense logic, high I/O count and deterministic timing, this commercial-grade device combines segmentable clocks, PLLs and flexible multi-standard I/Os with a low-voltage core supply for compact, high-throughput designs.

Key Features

• Core Capacity  Approximately 1,000,000 equivalent system gates and 18,144 logic elements for complex logic integration and high resource utilization.
• Embedded Memory  Contains 165,888 total RAM bits—approximately 0.166 Mbits—organized as multiple core RAM blocks with programmable FIFO control logic for buffering and data-path acceleration.
• I/O and Interfaces  317 user I/Os with bank-selectable, multi-voltage operation (1.5V, 1.8V, 2.5V, 3.3V) and support for differential and single-ended standards, including LVDS and LVPECL; LVDS I/Os are specified for 700 Mb/s capability.
• Performance and Timing  Architecture supports 350+ MHz system performance and 500+ MHz internal performance, plus segmentable clock resources and embedded PLLs for flexible clock synthesis and deterministic timing.
• Nonvolatile Antifuse Technology  CMOS antifuse process (0.15 μm, seven metal layers) provides a single-chip, nonvolatile solution suitable for applications that require one-time programmable configuration and design security.
• Power and Supply  Core supply range 1.425 V to 1.575 V for low-voltage operation; I/O banks support mixed-voltage interfacing to reduce level-shifting requirements.
• Package and Mounting  484-FPBGA (23×23) package, 484-BGA case, surface-mount mounting for dense PCB layouts.
• Commercial Grade  Rated for operation from 0 °C to 70 °C and RoHS-compliant.
• Design Security and Test  Includes FuseLock programming technology for protection against reverse engineering and supports boundary-scan (IEEE 1149.1) and Microchip Silicon Explorer II for in-system diagnostics and debug.

Typical Applications

• High-Speed Communications  Use as protocol bridges, serializers/deserializers and data-path controllers where LVDS-capable I/Os and high internal throughput are required.
• Network and Telecom Equipment  Implement packet processing, buffering and timing-critical functions leveraging embedded FIFOs, PLLs and deterministic timing resources.
• Instrumentation and Test  Suitable for measurement and test systems that need dense logic, on-chip RAM for acquisition buffering, and precise clocking.
• Embedded System Integration  Consolidate glue logic, peripheral interfacing and custom accelerators on a single nonvolatile device to reduce BOM and board area.

Unique Advantages

• High integration density: One million equivalent gates and 18,144 logic elements allow consolidation of large functions into a single device, simplifying system design.
• On-chip buffering and memory: Approximately 0.166 Mbits of embedded RAM with programmable FIFO control reduces external memory requirements and improves data-path efficiency.
• Flexible I/O signaling: Bank-selectable, mixed-voltage I/Os and high-speed LVDS support enable direct interfacing with a broad range of high-speed transceivers and legacy logic levels.
• Deterministic timing and clocking: Segmentable clocks and embedded PLLs support complex clocking schemes and predictable timing closure for high-speed designs.
• Nonvolatile, secure configuration: Antifuse-based single-chip configuration with FuseLock enhances design security and eliminates the need for external configuration memories.
• Compact surface-mount packaging: 484-FPBGA (23×23) provides a high-pin-count, space-efficient package for dense PCB implementations.
