A54SX72A-1PQG208M

Overview

The A54SX72A-1PQG208M is a nonvolatile Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 configurable logic blocks within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It operates within an industrial temperature range of -40°C to +85°C and utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for permanent configuration.

Feature Summary

• Supports hot-swap capabilities and power-up/down without voltage sequencing requirements
• Includes IEEE 1149.1 compliant boundary-scan testing via JTAG interface
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering
• Provides deterministic timing through segmented routing and dedicated clock networks

Applications

• Industrial control systems requiring high reliability
• Military and aerospace applications utilizing radiation-hardened or extended temperature grades
• Automotive electronics demanding mixed-voltage I/O compatibility
• High-performance digital signal processing and state machine implementations

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status and check for end-of-life notifications as the SX-A family has reached maturity. Ensure storage conditions respect moisture sensitivity levels prior to reflow soldering.

Selection Notes

Select this model for designs requiring 108,000 system gates in a PQFP-208 footprint. The -1 speed grade offers approximately 15% faster performance than standard variants. Verify that the 208-pin package aligns with PCB layout constraints and thermal management requirements for industrial environments.

Part Context

This part belongs to the Actel SX-A FPGA family, which bridges the gap between CPLDs and larger FPGAs. The SX-A series is characterized by its nonvolatile antifuse architecture, eliminating the need for external configuration memory. It serves as a drop-in replacement for complex CPLDs while offering higher density and performance.

Replacement Considerations

Direct pin-compatible replacements are limited due to the specific antifuse architecture. Consider the A54SX72A-FGG256I for FBGA packaging options or the AX500 series for newer Axcelerator-based solutions if migration is feasible.
