A54SX32A-1TQG144M

The A54SX32A-1TQG144M is a military-grade SX-A family field programmable gate array from Microchip Technology. It provides a nonvolatile, single-chip FPGA architecture with 2,880 logic elements and 48,000 system gates, delivering deterministic timing and flexible I/O for high-reliability embedded designs.

Designed for applications that demand wide operating temperature range and robust I/O support, this device targets military and other high-reliability markets where temperature tolerance, configurable I/O voltages and in-system testability are required.

Key Features

• Logic Capacity – Approximately 48,000 system gates implemented across 2,880 logic elements for medium-complexity FPGA functions.
• I/O Count & Flexibility – 113 user-programmable I/O pins with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling.
• Performance – SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family-level data).
• Voltage & Power – Wide supply range of 2.25 V to 5.25 V and support for mixed 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance and 5 V drive strength.
• Package & Mounting – 144-pin LQFP package (supplier device package: 144-TQFP, 20×20) in a surface-mount form factor suitable for high-reliability assemblies.
• Temperature & Grade – Military grade device with operating temperature range from −55 °C to +125 °C.
• Memory – On-chip RAM: 0 total RAM bits; combinational and sequential logic realized using logic elements (2,880) and dedicated flip-flops per device architecture.
• Nonvolatile Single-Chip – Family-level single-chip nonvolatile configuration eliminates the need for separate configuration memory.
• I/O & System Features – Hot-swap compliant I/Os, power-up/power-down friendly operation (no supply sequencing required), selectable weak pull-up or pull-down on I/O at power-up, and individual output slew rate control (family-level).
• Test & Security – Boundary-scan (IEEE 1149.1/JTAG) support and Actel Secure Programming technology with FuseLock™ for protection against reverse engineering (family-level).

Typical Applications

• Military & Aerospace Systems – Leverage military-grade temperature range and wide-voltage support for control, data routing and interface consolidation in rugged environments.
• High-Reliability Embedded Control – Implement deterministic logic and timing for mission-critical control, signal processing and embedded sequencing.
• PCI and Bus Interface Design – Support for 66 MHz PCI signaling and multiple I/O voltage standards enables protocol bridging and legacy bus interfacing.
• In-System Diagnostics & Verification – Use built-in boundary-scan and family-level in-system diagnostic capabilities for board-level test and verification workflows.

Unique Advantages

• Wide Operating Range: Military-grade temperature rating (−55 °C to +125 °C) ensures suitability for extreme-environment deployments.
• Flexible Voltage Interfacing: Broad supply range (2.25 V–5.25 V) and configurable I/O levels simplify mixed-voltage system integration.
• Nonvolatile, Single-Chip Configuration: Eliminates external configuration memory and simplifies system boot and field updates.
• Robust I/O Feature Set: Hot-swap compliance, power-up friendly behavior and selectable pull options reduce board-level sequencing and interface complexity.
• Security & Testability: Boundary-scan and FuseLock™ secure programming provide design protection and support for production test flows.
