A54SX32A-1FG256M

The A54SX32A-1FG256M is a military-grade SX-A family FPGA provided by Microchip Technology. It delivers a nonvolatile, single-chip programmable logic solution tailored for applications requiring deterministic timing and high reliability across a wide temperature range.

Built with 48,000 system gates and 2,880 logic elements, this device targets military and high-reliability embedded designs that need configurable I/O, hot-swap tolerant interfaces, and mixed-voltage operation from 2.25 V to 5.25 V.

Key Features

• Logic Capacity  48,000 system gates and 2,880 logic elements with up to 2,012 dedicated flip-flops (device-level resources from the SX-A family).
• I/O and Interfaces  203 user I/Os with configurable support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling; hot-swap compliant I/Os and selectable weak pull-up/pull-down at power-up.
• Performance  Family-level performance targets include up to 250 MHz system performance and 350 MHz internal performance; this specific part is designated with a –1 speed grade (~15% faster than standard per the SX-A family definition).
• Power and Voltage  Mixed-voltage operation across 2.5 V, 3.3 V and 5 V domains with 5 V input tolerance and 5 V drive strength; device supply range 2.25 V to 5.25 V.
• Nonvolatile Single-Chip Architecture  Nonvolatile configuration eliminates the need for external configuration memory for single-chip deployment.
• Package and Mounting  256-pin fine-pitch BGA in a 17 × 17 mm FPBGA package (surface-mount), specified for military temperature ranges.
• Reliability and Test  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and secure programming technology (FuseLock™) to protect design IP.
• Operating Range  Military-grade temperature rating from −55 °C to 125 °C and RoHS-compliant.
• On-Chip Memory  Total RAM Bits: 0 (no embedded RAM in this device).

Typical Applications

• Defense and Military Systems  High-reliability programmable logic for control, signal processing, and interface tasks across −55 °C to 125 °C environments.
• Secure Embedded Designs  Nonvolatile configuration and FuseLock™ secure programming are suited to applications requiring IP protection and in-field security.
• PCI and Legacy Interface Bridging  Configurable I/O with 66 MHz PCI support and mixed-voltage tolerance enables board-level interfacing and legacy bus integration.
• High-Reliability System Glue Logic  Deterministic timing and a single-chip solution simplify complex glue logic, protocol conversion, and control functions in ruggedized systems.

Unique Advantages

• Military-Grade Qualification: Specified operating range to −55 °C to 125 °C and military-grade packaging support deployment in harsh environments.
• Deterministic, Nonvolatile Architecture: Single-chip, nonvolatile configuration removes external configuration dependencies and enables predictable startup behavior.
• Flexible Mixed-Voltage I/O: Support for multiple I/O standards and 5 V tolerance simplifies system integration with a variety of legacy and modern interfaces.
• Secure Programming and Testability: FuseLock™ secure programming and IEEE 1149.1 boundary scan support increase design protection and board-level test coverage.
• Compact, Surface-Mount Package: 256-FPBGA (17×17) offers a high pin count in a compact BGA footprint for space-constrained, high-density boards.
