A54SX32A-PQG208I

Overview

The A54SX32A-PQG208I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and 1,452 configurable logic blocks (CLBs). The device features 174 user-programmable I/Os within a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates at a standard speed grade with a maximum system performance of 250 MHz and internal clock frequencies up to 350 MHz. The component supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V, and is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal programmable interconnect elements
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1

Applications

• High-performance digital signal processing requiring deterministic latency
• Industrial control systems necessitating hot-swappable interface capabilities
• Secure embedded applications utilizing FuseLock anti-tamper technology
• Legacy PCI bus interfaces supporting 66 MHz compliance

Procurement Notes

Verify the specific ordering suffix PQG208I against current manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as packaging designations may vary. Ensure design tools support the SX-A family architecture prior to procurement.

Selection Notes

Select this model for designs requiring high-speed logic with fixed, nonvolatile configuration. Consider the 208-pin PQFP footprint for board layout constraints. Evaluate the 174 available I/Os against interface requirements. Verify that the 250 MHz system performance meets timing closure goals for the target application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for low-power, high-density applications where security and deterministic performance are critical. It serves as a single-chip solution replacing multiple complex programmable logic devices.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be verified via official substitution lists. Cross-family migration to Axcelerator or SmartFusion requires architectural redesign due to differences in configuration memory and routing resources.
