A54SX08A-TQG144

Overview

The A54SX08A-TQG144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 12,000 system gates and 768 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates with supply voltages ranging from 2.25 V to 5.25 V. It delivers 250 MHz system performance and 350 MHz internal clock speeds. The component is designed for commercial applications with an operating temperature range of 0°C to +70°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for nonvolatile configuration and permanent low-impedance connections.
• Supports hot-swap capabilities and power-up/down sequences without requiring specific voltage sequencing.
• Includes IEEE 1149.1 compliant boundary-scan testing for diagnostic verification.
• Features FuseLock security technology to prevent reverse engineering and unauthorized design access.

Applications

• Integration of complex CPLD functionality into single-chip solutions
• High-performance state machine and fast counter implementations
• PCI-compliant interface designs

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as packaging options vary. Check current availability through authorized distributors, as lead times may apply for this legacy series.

Selection Notes

Select the A54SX08A-TQG144 when 12,000 system gates and 113 I/Os are required in a TQFP-144 form factor. Ensure the design utilizes the 2.5V to 5.25V supply range. Consider the commercial temperature grade limits if operating outside 0°C to +70°C.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi and subsequently Microchip Technology. The SX-A line is characterized by its antifuse-based architecture, offering deterministic timing and high-speed performance suitable for replacing multiple discrete logic components.

Replacement Considerations

Direct pin-compatible replacements within the same package and gate count are limited due to the discontinuation of the SX-A antifuse platform. Review the broader SX-A family datasheet for alternative packages or higher-density devices like the A54SX16A if resource requirements change.
