A54SX32A-PQG208M

Overview

The A54SX32A-PQG208M is a nonvolatile FPGA from the Microchip SX-A family, featuring 48,000 system gates and 174 user I/Os. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology with a standard speed grade. The device operates at a nominal voltage of 2.5 V, supporting a range of 2.25 V to 2.75 V. It provides up to 1,452 dedicated flip-flops and supports mixed-voltage I/O standards including 3.3 V and 5 V PCI, TTL, LVTTL, and LVCMOS2. The component is housed in a 208-pin PQFP package and is rated for commercial temperature operation (0°C to +70°C).

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Configurable weak-resistor pull-up or pull-down capabilities for deterministic I/O states during power-up.
• Supports Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 via JTAG interface.

Applications

• High-performance logic integration requiring deterministic timing and low power consumption.
• Systems requiring hot-swappable peripheral interfaces and mixed-voltage I/O compatibility.
• Applications necessitating secure, nonvolatile configuration without external bitstream memory.

Procurement Notes

Verify the specific ordering suffix 'PQ' corresponds to the Plastic Quad Flat Pack package type and 'G' indicates RoHS compliant packaging if required. Confirm that the standard speed grade meets the target system frequency requirements, as faster grades utilize different suffixes. Ensure the commercial temperature range aligns with the operational environment specifications.

Selection Notes

Select this device when 48,000 system gates and 174 I/Os are sufficient for the design. Consider the 208-pin PQFP package constraints regarding PCB space and thermal dissipation. Verify that the 2.5 V core voltage and mixed I/O voltage requirements match the system power rails. Note that the standard speed grade may require verification against maximum clock frequencies needed for the application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse-based nonvolatile architecture. The family ranges from 12,000 to 108,000 system gates, offering various package options and temperature grades. The SX-A series is designed for applications requiring high performance, security, and flexibility in mixed-voltage environments.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A such as A54SX32A-1PQG208M or A54SX32A-2PQG208M. Cross-family migration to newer Microchip FPGA architectures requires significant schematic and software redesign due to architectural differences.
