A54SX16P-TQ144M

Overview

The A54SX16P-TQ144M is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It contains 1,452 Configurable Logic Blocks (CLBs) and provides 24,000 system gates. The device supports up to 360 user-programmable I/O pins and includes up to 2,012 dedicated flip-flops. It operates with internal clock frequencies reaching 350 MHz and system performance of 250 MHz. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package with a height of 1.4 mm. It supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V levels.

Feature Summary

• Utilizes metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections and high-speed signal propagation.
• Features DirectConnect and FastConnect routing resources that minimize antifuse usage within logic clusters for deterministic timing.
• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes FuseLock™ security technology to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile single-chip solutions without configuration bitstreams
• Applications needing mixed-voltage I/O interfacing with 5 V tolerance

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm military temperature grade specifications. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture. Confirm RoHS compliance status if required by assembly processes.

Selection Notes

Select this model for designs requiring 24,000 system gates with a 144-pin TQFP footprint. Consider the -2 speed grade characteristics if higher performance than standard is needed. Verify that the 3.3 V PCI I/O standard does not require hot-swap capability, as it is excluded from that feature set.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power applications. The family utilizes antifuse technology rather than volatile SRAM configurations, offering inherent security and nonvolatility. The SX-A series spans capacities from 8,000 to 108,000 system gates across various packages.
