A54SX32A-TQ100M

Overview

The A54SX32A-TQ100M is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 81 user-programmable I/O pins and operates within a commercial temperature range of 0°C to +70°C. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology, enabling internal clock frequencies up to 350 MHz and system performance up to 250 MHz. The component is housed in a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation with configurable I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability or requiring voltage sequencing.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for superior diagnostic and verification.

Applications

• Integration of complex CPLD functionality into a single high-performance chip
• Fast counters, state machines, and data path logic requiring deterministic timing
• Systems requiring hot-swappable interface capabilities

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as packaging options vary. Check for export control classifications such as ECCN 3A991D if applicable to your region. Ensure design tools are compatible with the SX-A architecture.

Selection Notes

Select this device when 48,000 system gates and 81 I/Os are required in a TQFP-100 form factor. Consider the -1 or -2 speed grades if higher performance than the standard grade is needed. Verify that the commercial temperature range meets the application requirements. Evaluate the need for JTAG pin reservation versus flexible mode usage during design.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance applications. The family includes devices ranging from 12,000 to 108,000 system gates. The SX-A architecture is characterized by its sea-of-modules organization and patented antifuse technology, distinguishing it from volatile SRAM-based FPGAs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers migrating from other FPGA families should verify pin compatibility and logic resource equivalence using Actel Designer software.
