A54SX32A-FG484M

Overview

The A54SX32A-FG484M is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 360 user-programmable I/O pins and includes 2,012 dedicated flip-flops. It features 250 MHz system performance with 350 MHz internal clock capability. The component operates at 2.5 V, 3.3 V, or 5 V with mixed-voltage support and 5 V input tolerance. It is housed in a 484-pin Fine Pitch Ball Grid Array (FBGA) package.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Features deterministic timing through metal-to-metal programmable antifuse interconnect elements
• Includes IEEE 1149.1 Boundary-Scan Testing for diagnostic and verification capabilities
• Provides Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• Integration of CPLD and FPGA functionality into single-chip solutions
• Designs requiring 66 MHz PCI compliance
• Applications needing mixed-voltage operation with 5 V input tolerance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm availability status as older speed grades may be discontinued. Ensure design tools are compatible with the SX-A architecture before procurement.

Selection Notes

Select this model for designs requiring high pin counts and mixed-voltage I/O standards. Verify that the FBGA-484 package fits the board layout constraints. Check if the standard speed grade meets the timing requirements or if a faster grade is necessary.

Part Context

This part belongs to the Microsemi (formerly Actel) SX-A family of FPGAs. The family utilizes nonvolatile antifuse technology, offering low power consumption and high performance. The A54SX32A variant sits between the A54SX16A and A54SX72A in terms of logic capacity within the series.

Replacement Considerations

Check for updated speed grades or packages within the A54SX32A series. Verify compatibility with newer Microchip FPGA families if upgrading.
