The AX1000-CQ352M is an Axcelerator antifuse FPGA implementing Microchip's AX architecture as a single-chip, nonvolatile programmable logic device. It delivers deterministic timing, on-chip embedded memory and FIFOs, and architecture-level security for designs that require stable, one-time-programmable logic.

Targeted at applications that demand secure, high-performance programmable logic in harsh environments, the device provides 1,000,000 gates, 18,144 logic elements, 198 user I/Os, and approximately 0.166 Mbits of embedded memory. It is supplied in a 352-BFCQFP with tie bar surface-mount package and is rated for military temperature operation.

Key Features

• Core Architecture  Antifuse Axcelerator (AX) architecture offering a single-chip, nonvolatile implementation with 1,000,000 equivalent system gates and 18,144 logic elements for complex logic integration.
• Embedded Memory & FIFOs  Approximately 0.166 Mbits of embedded SRAM/FIFO implemented as variable-aspect 4,608-bit RAM blocks; embedded FIFO control logic is supported for high-throughput buffering.
• I/O Flexibility  198 user I/Os with bank-selectable multi-voltage operation (1.5V, 1.8V, 2.5V, 3.3V), support for single-ended and differential standards (including LVDS and LVPECL), registered I/Os, and programmable drive/slew settings.
• Clocking & PLL  Segmentable clock resources and an embedded PLL with a 14–200 MHz input range and frequency synthesis capabilities up to 1 GHz for flexible clocking and timing architectures.
• Performance  Series-level performance characteristics include 350+ MHz system performance and 500+ MHz internal performance to support timing-critical designs.
• Security & Reliability  FuseLock™ programming technology for protection against reverse engineering, single-chip nonvolatile configuration, and military-grade operating temperature range (−55°C to 125°C).
• Package & Power  Surface-mount 352-BFCQFP with tie bar (supplier package 352-CQFP, 75×75). Core supply voltage specified at 1.425 V to 1.575 V and RoHS compliant.

Typical Applications

• Military and Aerospace Systems  Military-grade temperature range and FuseLock security make the device suitable for secure, ruggedized systems that require nonvolatile programmable logic.
• High-Speed Serial Interfaces  LVDS-capable I/Os (700 Mb/s capable per series) and embedded FIFO support enable implementation of high-speed serial links and serial deserialization/serialization functions.
• Network & Communications  High internal performance and PLL frequency synthesis support timing-critical packet processing, protocol handling, and custom network functions.
• Instrumentation & Test Equipment  Deterministic timing, embedded FIFOs and on-chip diagnostic capabilities support precision data capture, buffering and deterministic control tasks.

Unique Advantages

• Design Security: FuseLock programming protects bitstream IP and helps prevent reverse engineering.
• Nonvolatile, Single-Chip Solution: Antifuse architecture provides persistent configuration without external configuration memory.
• Wide Operating Temperature: Rated −55°C to 125°C for deployment in harsh and mission-critical environments.
• Deterministic Timing & Diagnostics: User-controllable timing and in-system diagnostic/debug capability with Microchip tools for predictable system behavior and observability.
• Flexible I/O Standards: Bank-selectable multi-voltage I/Os and support for differential and single-ended standards simplify interface design across mixed-voltage systems.
• Compact Surface-Mount Packaging: 352-BFCQFP with tie bar enables board-level integration while matching the mechanical and thermal needs of demanding designs.
