AX500-FGG484

The AX500-FGG484 is an Axcelerator Field Programmable Gate Array from Microchip Technology based on the AX antifuse architecture. It provides a single‑chip, nonvolatile FPGA implementation with 500,000 equivalent system gates, 8,064 logic elements, and approximately 73.7 kbits of embedded RAM.

Designed for applications that demand deterministic timing, embedded FIFO memory and high‑speed I/O capability, the device combines 317 user I/Os, high internal performance and programmable routing in a 484‑ball fine BGA (23 × 23) surface‑mount package. The device is RoHS‑compliant and specified for commercial temperature operation.

Key Features

• Core Capacity  500,000 equivalent system gates with 8,064 logic elements (cells) to implement moderately complex custom logic and control functions.
• Embedded Memory  Approximately 73.7 kbits of on‑chip RAM with variable‑aspect RAM blocks and embedded FIFO control logic for buffering and data‑path implementations.
• I/O Count & Flexibility  317 user I/Os in an 8‑bank architecture (family feature set) supporting mixed‑voltage operation and a variety of single‑ended and differential standards as documented for the Axcelerator family.
• High‑Speed I/O Capability  Family‑level support for 700 Mb/s LVDS‑capable I/Os and programmable drive/slew settings to match interface requirements.
• Performance & Timing  AX architecture delivers high internal performance and deterministic timing; family specifications indicate 350+ MHz system performance and 500+ MHz internal performance.
• Nonvolatile Antifuse Technology  Single‑chip antifuse programming with FuseLock™ programming technology to protect design IP against reverse engineering.
• Power & Supply  Core operating supply specified at 1.425 V to 1.575 V (nominal ~1.5 V) for low‑voltage core operation.
• Package & Mounting  484‑ball fine BGA (484‑FPBGA, 23 × 23) surface‑mount package for high‑density board integration in commercial applications.
• Commercial Temperature Range  Specified for operation from 0 °C to 70 °C for commercial‑grade deployments.
• Standards & Test  Family features include IEEE 1149.1 (JTAG) boundary‑scan support for board‑level testability.

Typical Applications

• High‑Speed Communications  Use the AX500 for protocol bridging and interface aggregation where LVDS and high‑speed single/differential I/O capability is required.
• Data Buffering and Packet Processing  Embedded RAM and programmable FIFO control logic allow efficient implementation of buffering, packet queueing and streaming data paths.
• Secure, Nonvolatile Logic  Antifuse nonvolatile programming and FuseLock™ protection make the device suitable for designs requiring one‑time programmable hardware and IP protection.
• Custom Logic Integration  Implement control, glue logic, or custom state machines in a compact BGA package while keeping board BOM low and integration high.

Unique Advantages

• Single‑Chip Nonvolatile Solution: Antifuse technology provides a persistent configuration without external configuration memory.
• Deterministic Performance: AX architecture and family timing features support predictable timing for latency‑sensitive designs.
• Built‑In FIFO and Memory: Embedded RAM blocks with FIFO control simplify data path and buffering implementations, reducing external memory needs.
• Flexible I/O Capability: High I/O count and family support for mixed‑voltage and differential standards enable a wide range of interface options on a single device.
• Compact, Surface‑Mount Packaging: 484‑ball FPBGA (23 × 23) delivers high pin density in a manufacturable surface‑mount form factor.
• Design Security: FuseLock™ programming technology helps protect intellectual property against reverse engineering and unauthorized readout.
