A54SX08A-1TQ100I

Overview

The A54SX08A-1TQ100I is an industrial-grade Field Programmable Gate Array from the Microchip SX-A family, housed in a 100-pin Thin Quad Flat Pack (TQFP) package. It provides 12,000 system gates and supports up to 81 user-programmable I/O pins. The device operates within a voltage range of 2.25V to 5.25V and functions reliably across temperatures from -40°C to +85°C. Featuring 768 logic modules, it delivers 250 MHz system performance with 350 MHz internal clock capability.

Feature Summary

• Supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Hot-swap compliant I/Os allow safe insertion into active systems without power sequencing requirements
• Includes IEEE 1149.1 Boundary-Scan Testing for diagnostic verification
• Utilizes nonvolatile antifuse technology with FuseLock security to prevent reverse engineering

Applications

• Industrial control systems requiring deterministic timing
• PCI-compliant peripheral interfaces operating at 66 MHz
• Embedded logic integration replacing complex CPLDs or gate arrays

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm the specific ordering suffix matches the required temperature grade and package variant. Check for RoHS compliance status as standard packaging may differ from lead-free specifications. Ensure design files are compatible with current Actel Designer software versions.

Selection Notes

Select this model when 12,000 system gates and 81 I/Os meet design constraints. The -1 speed grade offers approximately 15% faster performance than standard variants. Verify that the TQFP package fits the PCB footprint and thermal requirements. Consider the -F grade if lower speed is acceptable for reduced power consumption.

Part Context

This component belongs to the SX-A FPGA family, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The series includes devices ranging from 12,000 to 108,000 system gates. The A54SX08A represents the entry-level capacity within this high-performance architecture, designed for cost-effective single-chip solutions.

Replacement Considerations

Compatible packages include the A54SX08A-1PQ208I (208-pin PQFP) and A54SX08A-1TQ144I (144-pin TQFP). These alternatives share identical logical resources but differ in pin count and physical dimensions. Verify pin compatibility before substitution.
