A54SX32-PQG208I

Overview

The A54SX32-PQG208I is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 174 user-programmable I/Os. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to achieve up to 350 MHz internal performance with a 250 MHz system clock speed. The device operates at 2.5 V, 3.3 V, or 5.0 V with mixed-voltage support and includes 1,080 dedicated flip-flops. It is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities for safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing for enhanced diagnostic and verification capabilities.

Applications

• 66 MHz PCI compliant interface integration
• High-performance state machine implementation
• Fast counter and data path logic design

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as standard packaging may differ from lead-free options. Check for any product discontinuation notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this model when 48,000 system gates and 208-pin PQFP packaging are required. Ensure the design benefits from nonvolatile antifuse technology and mixed-voltage I/O flexibility. Verify that the industrial temperature range meets environmental specifications.

Part Context

This component belongs to the Actel SX-A FPGA family, which uses metal-to-metal programmable antifuse interconnect elements. The architecture features a sea-of-modules design with register cells and combinatorial cells arranged in clusters for optimal resource utilization.

Replacement Considerations

Consult the official datasheet for alternative packages within the A54SX32A series, such as FBGA variants. Verify pin compatibility and electrical characteristics when considering cross-package replacements.
