A54SX32A-1PQ208

Overview

The A54SX32A-1PQ208 is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 1,452 Combinatorial Logic Blocks (CLBs). The device operates at a maximum system frequency of 167 MHz with an internal performance capability of 350 MHz. It features up to 924 dedicated flip-flops and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V PCI, TTL, LVTTL, and LVCMOS2. The component is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package and is rated for commercial temperature operation ranging from 0°C to +70°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse interconnects for permanent, low-impedance connections that prevent reverse engineering.
• Supports hot-swap operations and power-up/down sequences without requiring specific voltage sequencing or external configuration bitstreams.
• Includes DirectConnect and FastConnect routing resources to minimize signal propagation delays within logic clusters.
• Integrates IEEE 1149.1 compliant Boundary-Scan Testing capabilities for diagnostic verification.

Applications

• High-performance digital logic integration replacing complex CPLDs
• PCI-compliant interface designs operating at 66 MHz
• Systems requiring deterministic timing and pin-locking constraints

Procurement Notes

Verify the manufacturer origin, as Actel was acquired by Microchip Technology. Confirm the specific speed grade suffix '1' corresponds to the required performance level relative to standard devices. Ensure the PQFP package type matches the target PCB footprint requirements. Check for RoHS compliance status if lead-free assembly is mandated for the production environment.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. The -1 speed grade offers approximately 15% faster performance than the standard grade. Ensure the application requires commercial temperature range specifications. Verify that the 208-pin PQFP package fits the available board space and manufacturing capabilities.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes antifuse technology for nonvolatile configuration. The SX-A series is designed for mid-range applications requiring high reliability and security. The A54SX32A variant sits between the A54SX16A and A54SX72A in terms of logic capacity within the product line.

Replacement Considerations

Direct replacements include other speed grades of the A54SX32A such as A54SX32A-PQ208 or A54SX32A-2PQ208, provided timing requirements allow. Cross-family migration to PolarFire may be necessary for long-term supply assurance due to the discontinuation of older Actel lines.
