A54SX32A-1TQ144M

Overview

The A54SX32A-1TQ144M is a military-grade Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and 2,880 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates at a maximum frequency of 250 MHz with an internal performance of 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap capabilities and power-up/down friendly operation without requiring specific voltage sequencing.
• Includes dedicated boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• Military systems requiring high-performance logic in extreme temperature environments
• Spacecraft avionics utilizing nonvolatile FPGA architecture
• Harsh environment industrial control applications

Procurement Notes

Verify the 'M' suffix indicates the Military temperature grade (-55°C to +125°C). Confirm the '1' speed grade corresponds to approximately 15% faster performance than standard. Ensure the TQFP-144 package matches the target PCB footprint. Check for RoHS compliance status as packaging options vary.

Selection Notes

Select this part for designs requiring deterministic timing and high-speed logic processing in harsh conditions. The 48,000 system gates provide sufficient capacity for complex state machines and data path logic. Consider the 113 available I/Os for interface requirements and verify that the 250 MHz system performance meets the application's clocking needs.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are known for their cost-effective, low-power, and high-performance characteristics. The SX-A series integrates CPLD functionality into a single chip, offering significant improvements in time-to-market compared to traditional gate arrays.
