A54SX08A-1TQG144I

Overview

The A54SX08A-1TQG144I is a Field Programmable Gate Array from the SX-A family, featuring 12,000 system gates and 768 logic modules. It operates within a voltage range of 2.25 V to 3.6 V and supports up to 113 user-programmable I/O pins in a 144-pin Thin Quad Flat Pack (TQFP) package. The device delivers 250 MHz system performance with an internal clock frequency of 350 MHz. It includes three global clocks and utilizes nonvolatile antifuse technology for permanent configuration.

Feature Summary

• Supports mixed-voltage operation at 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 sequencing requirements
• Includes IEEE 1149.1 (JTAG) boundary-scan testing for diagnostic verification
• Provides deterministic timing through patented metal-to-metal antifuse interconnect

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters
• Data path logic requiring low propagation delays
• Systems requiring secure programming and reverse engineering prevention

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix if RoHS compliance is required, as standard packaging may differ. Ensure the TQFP-144 package matches the target PCB footprint. Check current availability status as older antifuse families may have limited stock or end-of-life considerations.

Selection Notes

Select this model for designs requiring 12,000 system gates with high-speed deterministic routing. The -1 speed grade indicates approximately 15% faster performance than the standard grade. Ensure the design fits within the 768 logic modules and 512 dedicated flip-flops available in the A54SX08A architecture. Verify that the 113 available I/Os meet the interface requirements for the target application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a cost-effective alternative to gate arrays. The A54SX08A variant represents the entry-level capacity within this specific family tier.

Replacement Considerations

Public confirmed substitute part numbers: A54SX08A-1TQG144G (RoHS compliant version), A54SX08A-TQG144I (Standard speed grade equivalent).
