A54SX32-1TQ144I

Overview

The A54SX32-1TQ144I is a 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 2,880 logic modules (CLBs). The device supports up to 249 user-programmable I/O pins and features 1,080 dedicated flip-flops. It operates with an internal clock frequency of 350 MHz and a system performance of 250 MHz. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Features hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources
• Provides secure programming capabilities via FuseLock technology to prevent reverse engineering

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing
• Systems requiring boundary-scan testing compliance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm availability status as older speed grades or packages may be discontinued. Ensure design tools support the SX-A antifuse architecture for proper configuration.

Selection Notes

Select this model for designs requiring 48,000 system gates within a 144-pin TQFP footprint. The Industrial temperature grade (-40°C to +85°C) suits environments beyond commercial limits. Verify that the 250 MHz system performance meets the target application timing constraints compared to faster or slower speed grades.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes nonvolatile antifuse technology. The family includes devices ranging from 12,000 to 108,000 system gates. The SX-A series is characterized by its sea-of-modules architecture and metal-to-metal programmable interconnects, offering high density and low power consumption.
