AX1000-BG729M

The AX1000-BG729M is an Axcelerator family Field Programmable Gate Array from Microchip Technology built on the AX antifuse architecture. This single-chip, nonvolatile FPGA integrates high-density logic (1,000,000 equivalent system gates), substantial embedded memory, and flexible, multi-standard I/Os to address high-performance, security-sensitive designs.

Designed for military-grade applications and demanding operating environments, the device combines deterministic timing, segmentable clocks, and embedded PLLs with high-speed I/O capabilities to support complex system integration and on-chip data buffering.

Key Features

• Core Capacity – Approximately 1,000,000 equivalent system gates implemented with 18,144 logic elements (cells) for complex logic integration.
• Embedded Memory – 36 core RAM blocks providing a total of 165,888 bits (approximately 0.166 Mbits) of embedded SRAM/FIFO with programmable FIFO control logic and independent, width-configurable read/write ports.
• I/O Density & Standards – 516 user I/Os with bank-selectable, mixed-voltage operation (1.5V, 1.8V, 2.5V, 3.3V) and support for single-ended and differential standards including LVDS and LVPECL; up to 258 LVDS channels on the AX1000 device.
• Performance – System and internal performance characteristics from the Axcelerator family include 350+ MHz system performance and 500+ MHz internal performance (family-level values), and I/Os capable of up to 700 Mb/s.
• Clocking & PLLs – Segmentable clock resources and embedded PLLs (eight PLLs for the AX1000) with a 14–200 MHz input range and frequency synthesis capability.
• Nonvolatile Antifuse Technology & Security – CMOS antifuse programming with FuseLock™ technology to protect design IP against reverse engineering and design theft.
• Power & Supply – Core supply specified at 1.425 V to 1.575 V; datasheet references a 1.5 V core voltage for low-power operation.
• Package & Temperature – 729-BBGA (supplier package 729-PBGA, 35 × 35 mm), surface-mount package; military-grade operating temperature range of −55 °C to 125 °C.
• Diagnostics & Test – In-system diagnostic and debug capability with Microchip Silicon Explorer II and JTAG (IEEE 1149.1) boundary-scan support.
• Standards & Configurability – Bank-selectable I/Os, programmable slew rate and drive strength, and input pull options for flexible signal interfacing across multiple voltage domains.
• Environmental – RoHS compliant.

Typical Applications

• Military & Aerospace Systems – Military-grade temperature range and nonvolatile antifuse programming make the AX1000 suitable for defense and aerospace designs requiring rugged, secure programmable logic.
• High-Speed Data Processing – Embedded FIFOs, substantial on-chip SRAM and high internal performance support data buffering and real-time signal processing tasks.
• Secure, IP-Sensitive Designs – FuseLock programming technology and antifuse nonvolatile configuration protect proprietary logic and prevent reverse engineering.
• High-Density I/O Interfaces – Large I/O count and multi-standard, banked I/Os enable complex system interfacing, high-speed serial links (LVDS), and mixed-voltage board designs.

Unique Advantages

• High integration density: Combines 1,000,000 equivalent gates and 18,144 logic elements to reduce external glue logic and simplify system design.
• On-chip memory with FIFO control: Approximately 0.166 Mbits of embedded memory and programmable FIFO logic for efficient data flow and reduced external memory requirements.
• Robust I/O flexibility: Bank-selectable, multi-voltage I/Os and broad standard support (LVTTL, LVCMOS, LVDS, LVPECL, SSTL, HSTL, GTL+) streamline mixed-signal and high-speed interface design.
• Security through hardware programming: Antifuse-based nonvolatile configuration and FuseLock™ protect design IP and deter reverse engineering.
• Designed for harsh environments: Military-grade temperature range (−55 °C to 125 °C) and surface-mount 729-BBGA packaging support reliable operation in demanding conditions.
• Deterministic timing and debug: Segmentable clocking, embedded PLLs, and in-system diagnostic support via Microchip Silicon Explorer II enable controllable timing and efficient debug workflows.
