A54SX32-1TQ144M

Overview

The A54SX32-1TQ144M is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 113 user-programmable I/O pins in a 144-pin Thin Quad Flat Pack (TQFP) package. It operates with a maximum internal clock frequency of 350 MHz and a system performance of 250 MHz. The part utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes unique in-system diagnostic and verification capability with Silicon Explorer II and boundary-scan testing compliance with IEEE Standard 1149.1.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• 66 MHz PCI compliant designs
• CPLD and FPGA integration single-chip solutions
• Low-power, high-performance designs requiring deterministic timing

Procurement Notes

Verify the specific speed grade suffix '1' indicates approximately 15% faster performance than the standard speed grade. Confirm the 'M' suffix denotes military temperature range (-55°C to +125°C). Ensure the TQFP package type matches the design footprint requirements. Check for RoHS compliance status if required by the manufacturing process.

Selection Notes

Select this model when 48,000 system gates and 2,880 CLBs are sufficient for the logic density requirements. Choose the -1 speed grade for applications needing higher performance than the standard grade but less than the -2 grade. The TQFP144 package is suitable for designs prioritizing through-hole or standard surface mount compatibility over BGA densities. Verify voltage domain requirements against the supported 2.5V, 3.3V, and 5V I/O standards.

Part Context

This component 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 series is characterized by its antifuse-based nonvolatile architecture, distinguishing it from SRAM-based FPGAs that require external configuration memory. This family bridges the gap between CPLDs and traditional FPGAs in terms of pin count and performance.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as A54SX32-F1TQ144M (slower) or A54SX32-2TQ144M (faster), provided the timing constraints allow. Cross-family replacements like the A54SX25 or A54SX72 require significant schematic and layout changes due to different pin counts and resource distributions.
