A54SX32A-1TQG144M

Overview

The A54SX32A-1TQG144M is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum frequency of 263 MHz with a 2.5 V supply voltage range of 2.25 V to 2.75 V. The device utilizes a 144-pin Thin Quad Flat Pack (TQFP) package and supports up to 113 user-programmable I/Os. Designed for military applications, it functions within an operating temperature range of -55°C to +125°C.

Feature Summary

• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with 5 V input tolerance
• Features hot-swap compliant I/Os allowing power-up/down without sequencing requirements
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources
• Provides nonvolatile antifuse technology with FuseLock security features against reverse engineering

Applications

• Military aerospace systems requiring extended temperature ranges
• High-performance digital signal processing interfaces
• PCI-compliant data acquisition hardware
• Secure embedded control logic

Procurement Notes

Verify the specific ordering suffix 'M' confirms the military temperature grade (-55°C to +125°C). Confirm the package type matches the 144-pin TQFP requirement. Check for RoHS compliance status as standard packaging may differ from lead-free variants. Ensure design files support the specific speed grade associated with this part number.

Selection Notes

Select this component when military-grade environmental resilience is required alongside high-density programmable logic. The 144-pin TQFP package offers surface-mount convenience for board space constraints. Verify that the 48,000 gate capacity meets the design complexity needs compared to smaller SX-A devices like the A54SX16A.

Part Context

This part belongs to the Actel SX-A FPGA family, which uses metal-to-metal antifuse technology for permanent configuration. The SX-A series bridges the gap between CPLDs and larger FPGAs, offering single-chip solutions with low power consumption and high performance for complex logic integration.

Replacement Considerations

Direct replacements include other speed grades within the A54SX32A TQFP144 package such as the standard or industrial variants. Cross-family migration to Microchip PolarFire or IGLOO II requires significant architectural redesign due to differences in configuration memory and logic structure.
