AX500-1PQ208

The AX500-1PQ208 is an Axcelerator FPGA from Microchip Technology based on the AX architecture and antifuse CMOS programming technology. This single-chip, nonvolatile device delivers 500,000 equivalent system gates with 8,064 logic elements and approximately 0.074 Mbits (73,728 bits) of embedded SRAM/FIFO.

Designed for commercial applications, the device provides flexible multi-standard I/Os, on-chip PLLs and embedded FIFO control, making it suitable for high-performance system logic, custom interface bridging and designs that require deterministic timing and nonvolatile programming.

Key Features

• Core & Architecture AX antifuse architecture providing a single-chip, nonvolatile solution and deterministic timing characteristics.
• Logic Capacity 500,000 equivalent system gates and 8,064 logic elements to implement mid-density FPGA designs.
• Embedded Memory Approximately 73,728 bits of on-chip RAM across core RAM blocks with variable-aspect 4,608-bit RAM block organizations and embedded FIFO control logic.
• I/Os & Interface Flexibility 115 user I/Os with support for multi-voltage operation (1.5V, 1.8V, 2.5V, 3.3V), LVDS capability (family support up to 700 Mb/s), registered I/Os and programmable slew/drive characteristics.
• Performance Family-level performance targets include 350+ MHz system performance and 500+ MHz internal performance, supported by segmentable clock resources and on-chip PLLs (14–200 MHz input range, frequency synthesis up to 1 GHz).
• Power & Supply Core supply range of 1.425 V to 1.575 V for low-voltage operation.
• Packaging & Temperature 208-BFQFP surface-mount package (supplier package 208-PQFP, 28×28) rated for commercial temperature operation from 0 °C to 70 °C.
• Security & Programming FuseLock™ programming technology to protect against reverse engineering and support secure, one-time programming.
• Design & Test Support In-system diagnostic and debug capability (family support with Microchip Silicon Explorer II) and JTAG boundary-scan compliant with IEEE 1149.1.

Typical Applications

• High-performance system logic — Implement custom glue logic, state machines and high-speed datapaths that benefit from the device’s gate density and deterministic timing.
• Interface bridging and SERDES support — Use embedded FIFOs, LVDS-capable I/Os and on-chip PLLs to build robust protocol translators and high-speed interface endpoints.
• Custom ASIC replacement and integration — Replace or consolidate legacy ASIC functions into a single nonvolatile FPGA to reduce part count and simplify board design.
• In-system debug and diagnostics — Take advantage of the family’s in-system diagnostic features for bring-up and debug during development and production testing.

Unique Advantages

• Nonvolatile single-chip solution: Antifuse programming provides a one-time programmed device that retains configuration without external configuration memory.
• Deterministic timing and high internal performance: Segmentable clocks, on-chip PLLs and architecture-targeted routing support high-performance designs that require predictable timing behavior.
• Flexible, multi-standard I/Os: Bank-selectable I/O voltages and programmable I/O characteristics enable mixed-voltage interfacing and broad protocol support.
• Embedded FIFO and RAM control: Integrated RAM blocks with programmable FIFO control simplify high-throughput data buffering without large external memory.
• Secure programming: FuseLock™ technology protects IP by preventing reverse engineering of the programmed configuration.
• Compact surface-mount package: 208-BFQFP footprint allows deployment in space-constrained commercial designs.
