A54SX32-BGG329

Overview

The A54SX32-BGG329 is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 360 user-programmable I/O pins. The device operates with internal clock frequencies of 350 MHz and achieves 250 MHz system performance. It features mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. The component is housed in a 329-pin Plastic Ball Grid Array (PBGA) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes Silicon Explorer II for unique in-system diagnostic and verification capabilities alongside IEEE 1149.1 boundary-scan testing.
• Features FuseLock security technology to prevent reverse engineering and design theft.

Applications

• 66 MHz PCI compliant designs
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm temperature grade and packaging compliance. Confirm current availability status as product lifecycles may change. Ensure compatibility with existing PCB footprints for the 329-pin PBGA package before procurement.

Selection Notes

Select this model for applications requiring high-density logic within a compact BGA footprint. Consider the -B suffix for MIL-STD-883 Class B military qualification if required. Verify that the 329-pin pitch matches the target board layout constraints and thermal management requirements.

Part Context

This part belongs to the Actel SX-A FPGA family, which integrates CPLD and FPGA functionality into a single nonvolatile chip. The SX-A series is designed for cost-effective, low-power, high-performance designs using antifuse technology, distinguishing it from volatile SRAM-based FPGAs by eliminating configuration bitstreams.
