A54SX32A-1TQ144I

Overview

The A54SX32A-1TQ144I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2880 logic modules. It operates at a maximum frequency of 278 MHz with an industrial temperature range of -40°C to +85°C. The device utilizes a 144-pin Thin Quad Flat Pack (TQFP) package and supports up to 113 user-programmable I/O pins. Powered by 0.22 μm / 0.25 μm CMOS antifuse technology, it provides deterministic timing and nonvolatile configuration.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with hot-swap compliant capabilities.
• Features Deterministic, User-Controllable Timing with 100% resource utilization and pin locking.
• Includes Boundary-Scan Testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• Hot-Swap Compliant System Designs
• Deterministic Logic Control Applications

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the package type corresponds to the 144-pin TQFP variant. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture before procurement.

Selection Notes

Select this model for designs requiring 48,000 system gates within a 144-pin footprint. The '-1' speed grade offers approximately 15% faster performance than standard speed. Verify that the 113 available I/O pins meet interface requirements and that the industrial temperature range aligns with environmental constraints.

Part Context

This component belongs to the Microchip (formerly Actel) SX-A FPGA family, which utilizes antifuse technology for nonvolatile configuration. The SX-A series is designed for high-performance, low-power applications, offering a cost-effective alternative to multiple CPLDs or gate arrays in embedded systems.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Consult manufacturer documentation for cross-reference information regarding discontinued speed grades or package variations within the SX-A family.
