A54SX32A-FPQG208

Overview

The A54SX32A-FPQG208 is a Field Programmable Gate Array from the 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 operating voltage of 2.5 V (range 2.25 V to 2.75 V). The device supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V input tolerance. It includes three global clock networks and offers hot-swap compliant I/Os without supply sequencing requirements.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing
• Configurable I/O standards supporting 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2
• Deterministic timing performance enabled by DirectConnect and FastConnect routing resources

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays
• Systems requiring deterministic timing and fast counters or state machines
• Applications needing secure design protection against reverse engineering

Procurement Notes

Verify the specific speed grade suffix associated with the FPQG208 package designation, as standard speed grades are typically indicated by a blank space in the ordering code. Confirm that the 'G' suffix denotes RoHS compliant packaging if environmental compliance is required for the project specifications.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based devices to eliminate configuration memory requirements. Ensure the design leverages the 5 V tolerant I/O capabilities if interfacing with legacy 5 V logic levels while maintaining a 2.5 V core voltage.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated on a high-voltage twin-well CMOS process. The family provides a range of capacities from 12,000 to 108,000 system gates, with the A54SX32A offering a mid-range capacity optimized for moderate complexity designs requiring high performance.
