A54SX72A-1PQG208I

Overview

The A54SX72A-1PQG208I is an industrial-grade FPGA from the SX-A family, housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It provides 108,000 system gates and 6,036 logic modules, including 4,024 dedicated flip-flops. The device supports up to 360 user-programmable I/O pins and features three global routed clocks plus four quadrant clocks. Operating at speed grade -1, it delivers approximately 15% faster performance than standard grades with a maximum internal clock frequency of 350 MHz. It utilizes 0.22/0.25 μm CMOS antifuse technology and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnects for permanent low-impedance connections.
• Supports hot-swap capabilities and mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with configurable I/O standards.
• Includes deterministic routing resources such as DirectConnect and FastConnect for predictable signal propagation times.
• Integrates IEEE 1149.1 compliant Boundary-Scan Testing (JTAG) and Actel Secure Programming Technology with FuseLock.

Applications

• High-performance digital signal processing and data path logic requiring fast counters and state machines.
• Systems requiring deterministic timing and concurrent PCB development due to 100% pin-locking capability.
• Industrial control applications necessitating mixed-voltage I/O interfaces and hot-swappable power-up/down behavior.

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required speed grade (-1), package type (PQFP), and industrial temperature range (I). Ensure compliance with relevant export regulations and RoHS standards applicable to the manufacturing date code.

Selection Notes

Select this model when design requirements exceed the capacity of lower-density SX-A devices like the A54SX32A but do not require the higher density of future families. Consider the -1 speed grade if performance needs are between standard and -2 grades. Verify that the 208-pin PQFP footprint fits the target board layout and that the 350 MHz internal clock capability aligns with system timing constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microchip Technology. The SX-A series is characterized by its antifuse-based nonvolatile architecture, offering high reliability and security compared to volatile SRAM-based FPGAs. The A54SX72A represents the highest density option within this specific generation of the family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers migrating from discontinued speed grades should consult Microchip for current equivalent recommendations within the Axcelerator or ProASIC3 families.
