A54SX16-1PQG208

Overview

The A54SX16-1PQG208 is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It provides 24,000 system gates and 1,452 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 175 user-programmable I/Os and operates at a maximum system performance of 250 MHz with internal clock frequencies reaching 350 MHz. It features mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V standards, including PCI compliance. The component includes three global clock networks and complies with IEEE 1149.1 Boundary-Scan Testing.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Deterministic timing architecture with DirectConnect and FastConnect routing resources
• Integrated FuseLock security technology to prevent reverse engineering and design theft

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs requiring 66 MHz bus speeds
• Systems requiring deterministic timing and pin-locking capabilities
• Applications necessitating in-system programming and boundary-scan testing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the -1 speed grade designation aligns with project timing requirements, as it indicates approximately 15% faster performance than the standard grade. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture.

Selection Notes

Select this model when 24,000 system gates and 1,452 logic modules are sufficient for the design complexity. The PQFP208 package is suitable for surface-mount applications requiring 175 user I/Os. Consider the -1 speed grade if higher throughput is needed compared to the standard version. Verify that the 2.5V/3.3V/5V mixed-voltage I/O capabilities match the target system interfaces.

Part Context

This component belongs to the Microsemi SX-A family of FPGAs, which are fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers high-density logic resources with nonvolatile storage, eliminating the need for external configuration memory. The A54SX16 variant sits between the A54SX08 and A54SX32 devices in terms of capacity and resource availability.
