AX1000-1BG729

The AX1000-1BG729 is an Axcelerator family antifuse FPGA from Microchip Technology providing 1,000,000 equivalent system gates and a high-density, single-chip nonvolatile solution. It implements the AX architecture with embedded SRAM/FIFO control logic and on-chip clock and PLL resources to support demanding digital systems.

This commercial-grade, surface-mount device is optimized for applications that require large logic capacity, substantial I/O count, and embedded memory/FIFO resources while operating within a 1.425 V–1.575 V core supply and a 0 °C to 70 °C ambient range.

Key Features

• Core Logic  1,000,000 equivalent system gates with 18,144 logic elements (cells) for complex logic implementation and high integration density.
• Embedded Memory & FIFOs  Approximately 0.16 Mbits of embedded memory (165,888 total RAM bits) organized as variable-aspect 4,608-bit RAM blocks and programmable FIFO control logic for buffering and packet handling.
• I/O Capacity & Flexibility  516 user I/Os across bank-selectable I/O banks (8 banks per device) supporting mixed-voltage operation and multiple single-ended and differential standards as described for the Axcelerator family.
• Performance & Timing  Family-level performance characteristics include 350+ MHz system performance and 500+ MHz internal performance, plus segmentable clocks and embedded PLLs (frequency synthesis capabilities up to 1 GHz) for deterministic, user-controllable timing.
• Programmability & Security  Single-chip, nonvolatile antifuse programming with FuseLock™ technology to protect against reverse engineering and support 100% resource utilization with pin locking.
• Package & Mounting  729-BBGA package (supplier package: 729-PBGA, 35 × 35 mm) in a surface-mount form factor suitable for high-density board designs.
• Power & Operating Range  Core supply specified 1.425 V to 1.575 V (1.5 V nominal). Commercial operating temperature range: 0 °C to 70 °C. RoHS-compliant.

Typical Applications

• Data Packet Processing  Use embedded FIFOs and high logic density for packet buffering, protocol parsing and custom packet-processing pipelines.
• High-Speed I/O Bridging  Leverage the 516 user I/Os and multi-standard I/O support for interfacing between mixed-voltage subsystems and implementing high-speed serial or parallel interfaces.
• Custom DSP and Control Logic  Implement complex state machines, signal processing blocks, and control algorithms using the abundant logic elements and on-chip memory resources.
• System Timing and Clocking  Employ segmentable clock resources and embedded PLLs for frequency synthesis and tight timing control in synchronous systems.

Unique Advantages

• High integration density: Consolidate functions into a single nonvolatile FPGA with 1,000,000 gates and 18,144 logic elements to reduce BOM and board area.
• Built-in buffering and memory: Approximately 0.16 Mbits of embedded RAM with FIFO control logic simplifies dataflow designs and reduces external memory dependence.
• Flexible I/O strategy: 516 user I/Os across bank-selectable banks support mixed-voltage operation and common interface standards for versatile system integration.
• Deterministic timing control: Segmentable clocks and embedded PLLs enable precise clock management and frequency synthesis for demanding timing requirements.
• Security-aware programming: Antifuse programming with FuseLock™ provides nonvolatile configuration and protection against reverse engineering.
• Commercial-grade reliability: Specified for surface-mount assembly, RoHS compliance, and operation across the 0 °C–70 °C commercial temperature range.
