A54SX16A-1FG144M

Overview

The A54SX16A-1FG144M is a Field Programmable Gate Array from the Actel SX-A family, manufactured by Microsemi. It features 24,000 typical system gates and 1,452 logic modules within a 144-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at a maximum frequency of 263 MHz with a supply voltage range of 2.25 V to 2.75 V. It supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V PCI, TTL, LVTTL, and LVCMOS2. The component is rated for military temperature grades (-55°C to +125°C) and utilizes nonvolatile antifuse technology.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing insertion into electrically active systems without degrading host reliability or requiring specific power sequencing.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources to minimize signal propagation delays.
• Integrated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for in-system diagnostic verification.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Military and aerospace embedded control systems requiring extended temperature operation
• PCI-compliant interface controllers supporting 66 MHz bus speeds
• Secure hardware designs utilizing FuseLock technology to prevent reverse engineering

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm military temperature grade and lead-free packaging compliance. Confirm current production status as discontinuance notifications may affect availability. Ensure design files match the exact FBGA pinout for the 144-pin variant.

Selection Notes

Select this model when 24,000 system gates and 180 user I/Os are required in a compact FBGA form factor. The -1 speed grade offers approximately 15% faster performance than standard speed. Verify that the 2.5 V core voltage aligns with the target system's power delivery infrastructure and I/O requirements.
