A54SX32A-FBG329

Overview

The A54SX32A-FBG329 is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It supports up to 249 user-programmable I/O pins and operates with internal clock frequencies up to 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It is housed in a 329-pin Plastic Ball Grid Array (PBGA) package.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Features Boundary-Scan Testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• 66 MHz PCI Compliant System Integration
• Low-Power High-Performance Logic Designs
• Single-Chip CPLD Replacement Solutions

Procurement Notes

Verify the specific speed grade suffix associated with the FBG329 package variant, as performance characteristics vary by grade. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors, as supply chain data may change over time.

Selection Notes

Select this component when a nonvolatile single-chip FPGA solution with high pin count is required. Ensure the design accommodates the 329-pin PBGA footprint and meets the thermal dissipation requirements for the selected temperature grade. Verify that the 249 available I/Os match the interface specifications of the target application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The SX-A series is designed to offer cost-effective integration for designs previously requiring multiple CPLDs or gate arrays, providing high performance with low power consumption.
