A54SX32A-TQG144M

Overview

The A54SX32A-TQG144M is a nonvolatile Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates within a voltage range of 2.25 V to 2.75 V at a standard frequency of 238 MHz. The device provides 113 user-programmable I/Os in a 144-pin Thin Quad Flat Pack (TQFP) package with a 1.40 mm height. Designed for military applications, it supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Supports hot-swap operations and mixed-voltage I/O standards including 5V tolerance.

Applications

• Military aerospace systems requiring radiation-hardened or high-reliability logic
• Secure embedded control units utilizing FuseLock anti-tamper features
• Industrial automation controllers operating in extreme environmental conditions

Procurement Notes

Verify the specific suffix 'M' confirms the military temperature grade (-55°C to +125°C). Confirm RoHS compliance status as packaging options vary. Ensure design files account for the TQFP-144 footprint dimensions and thermal dissipation requirements for this specific package type.

Selection Notes

Select this model when 48K system gates are required alongside strict military temperature specifications. Compare against the A54SX32A-TQG144A if automotive grades suffice. Verify that the 113 available I/O pins meet interface requirements before choosing over higher pin-count packages like FBGA.

Part Context

This component belongs to the Actel SX-A series, now manufactured by Microchip Technology. The SX-A line is characterized by its high-performance antifuse architecture, offering deterministic timing and robust security features compared to volatile SRAM-based FPGAs.

Replacement Considerations

The A54SX32A-TQG144A serves as the automotive-grade equivalent. For industrial use, the A54SX32A-TQG144I is available. Direct functional replacements require matching the 144-pin TQFP form factor and 48K gate capacity.

FAQ

Does the A54SX32A-TQG144M require an external configuration bitstream?

No, the device uses nonvolatile antifuse technology, meaning the configuration is permanent and does not require external boot memory upon power-up.

What is the maximum internal clock frequency for this device?

While the system performance is rated at 250 MHz, the internal performance can reach up to 350 MHz depending on the specific speed grade and routing.

Can unused I/O pins be left floating?

No, unused I/Os must be configured as tristate outputs or tied to a defined logic level to prevent excessive current draw or signal interference.
