A54SX32-TQG144M

Overview

The A54SX32-TQG144M is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum internal frequency of 350 MHz with a typical system performance of 250 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and is rated for military temperature grades (-55°C to +125°C).

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Provides deterministic timing through user-controllable clock resources and segmented routing.
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• Mixed-Voltage Interface Designs with 5 V Input Tolerance
• High-Performance Logic Integration Requiring Deterministic Timing

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm military temperature grade availability and RoHS status. Confirm current production status as legacy FPGA families may have limited supply or discontinuation notices. Ensure design files match the exact speed grade associated with this part number.

Selection Notes

Select this component when designing systems requiring nonvolatile single-chip FPGA solutions with high-speed performance up to 350 MHz internal clocking. Consider the 144-pin TQFP package constraints and verify that the 2,880 logic module capacity meets the design complexity. Ensure compatibility with 2.5 V, 3.3 V, and 5 V I/O standards if mixed-voltage operation is required.

Part Context

This device belongs to the Actel SX-A family of FPGAs, which are fabricated using metal-to-metal programmable antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a sea-of-modules architecture with DirectConnect and FastConnect routing resources for optimal silicon utilization and predictable signal propagation.
