AX1000-FG484

The AX1000-FG484 is an Axcelerator antifuse-based FPGA from Microchip Technology that delivers a single-chip, nonvolatile programmable logic solution. Built on the AX architecture and an advanced 0.15 µm CMOS antifuse process with seven metal layers, this device provides 1,000,000 equivalent system gates, 18,144 logic elements and on-chip embedded memory for designs that require deterministic timing, in-system security and high internal performance.

Its combination of high-speed internal performance, flexible multi-voltage I/O options and hardware clock/PLL resources makes it suitable for applications that demand reliable, nonvolatile programmable logic with embedded memory and FIFO control.

Key Features

• Core Capacity — 1,000,000 equivalent system gates and 18,144 logic elements provide substantial logic resources for complex designs.
• Embedded Memory — 36 core RAM blocks delivering a total of 165,888 bits (approximately 0.166 Mbits) of embedded SRAM/FIFO with programmable FIFO control logic and independent, width-configurable read and write ports.
• I/O Flexibility — 317 user I/Os with bank-selectable, mixed-voltage operation supporting 1.5V, 1.8V, 2.5V and 3.3V signaling and a variety of single-ended and differential standards as described in the Axcelerator family feature set.
• High-Speed Performance — Family-level performance includes 350+ MHz system performance and 500+ MHz internal performance; LVDS-capable I/Os support up to 700 Mb/s.
• Clocking and PLLs — Segmentable clock resources and an embedded PLL with a 14–200 MHz input range and frequency synthesis capabilities up to 1 GHz enable precise timing and clock management.
• Power and Supply — Core supply range of 1.425 V to 1.575 V (nominal 1.5 V core) for low-power operation.
• Package and Mounting — Surface-mount 484-ball FPBGA package (23 × 23) for high-density board integration; commercial grade operation from 0 °C to 70 °C.
• Security and Test — Single-chip nonvolatile antifuse programming with FuseLock programming technology for protection against reverse engineering, plus boundary-scan testing compliant with IEEE 1149.1 (JTAG).
• Diagnostics and Tools — Supports unique in-system diagnostic and debug capability with Microchip Silicon Explorer II for development and field diagnostics.
• Environmental Compliance — RoHS-compliant.

Typical Applications

• ASIC Replacement and Prototyping — Use as a nonvolatile programmable alternative where ASIC-level performance and security are required while retaining the flexibility to update logic in development phases.
• High-Performance Logic — Implement high-speed datapath and control logic that benefits from the device’s internal performance, embedded FIFOs and PLL-based clock synthesis.
• Custom I/O and Interface Bridging — Leverage mixed-voltage, bank-selectable I/Os and differential signaling capability to implement interface conversion and high-speed serial/parallel link functions.

Unique Advantages

• Single-Chip, Nonvolatile Solution: Eliminates the need for external configuration memory while protecting designs through antifuse programming and FuseLock technology.
• Substantial On-Chip Resources: Combines one million equivalent gates with approximately 0.166 Mbits of embedded RAM across 36 blocks, reducing external memory requirements and simplifying board-level design.
• High Internal and System Performance: Family-level performance metrics support demanding timing requirements and high-throughput data paths.
• Flexible I/O Standards: Bank-selectable mixed-voltage I/Os and support for a wide range of single-ended and differential standards enable broad interface compatibility.
• Deterministic Timing and Clocking: Segmentable clocks and an on-chip PLL enable controlled, predictable timing for complex synchronous designs.
• Design Security and Testability: Antifuse programming with FuseLock protection plus IEEE 1149.1 boundary-scan provide both IP protection and standardized test access.
