A54SX32-2TQ144I

The A54SX32-2TQ144I is an SX-family FPGA from Microchip Technology offering a nonvolatile, single-chip programmable solution in a 144-pin LQFP package. It delivers 48,000 system gates and 2,880 logic elements with 113 user I/Os, suitable for industrial-temperature applications requiring mixed-voltage interfacing and in-system programmability.

This device targets designs that need deterministic timing, configurable I/O voltage support, and a compact surface-mount package while operating across a 3 V to 5.5 V supply range and an operating temperature of −40 °C to +85 °C.

Key Features

• Logic Capacity – 48,000 system gates and approximately 2,880 logic elements provide the programmable logic resources for medium-density designs.
• User I/O – 113 user-programmable I/Os allow flexible external interfacing for mixed-signal and digital peripherals.
• Performance – Family-level performance indicators list up to 250 MHz system performance and up to 350 MHz internal performance; this part is the –2 speed grade (approximately 25% faster than standard).
• Nonvolatile, Single-Chip Configuration – On-chip nonvolatile configuration eliminates the need for external configuration memory and supports in-system reprogramming and diagnostics.
• Configurable Multi-Voltage I/O – Family features include support for 5 V, 3.3 V, and 2.5 V I/O standards and 5 V input tolerance, enabling mixed-voltage interface designs.
• Robust System Features – Boundary-scan (JTAG) support and in-system diagnostic/verification capability help streamline development and production test.
• Package & Mounting – 144-pin LQFP package (supplier variant: 144-TQFP 20×20), surface-mount; compact package for space-constrained PCBs.
• Power and Temperature – Wide supply range from 3 V to 5.5 V and industrial operating temperature rating from −40 °C to +85 °C.
• Compliance – RoHS compliant.

Typical Applications

• PCI and Legacy Bus Interfaces – PCI-compliant family support and configurable I/O make the device suitable for bridging and logic functions on PCI-based boards.
• Mixed-Voltage Interface Bridging – Configurable I/O voltage support and 5 V input tolerance allow the FPGA to interface between different logic domains without external level-shifters.
• Industrial Control and Automation – Industrial temperature grade and deterministic logic resources fit control logic, glue logic, and protocol handling in industrial systems.
• Embedded System Glue Logic – Nonvolatile configuration and a compact LQFP footprint suit applications that require persistent programmable logic in small form factors.

Unique Advantages

• Nonvolatile Single-Chip Solution: Eliminates external configuration memory and simplifies BOM and board layout.
• Mixed-Voltage I/O Flexibility: Supports 2.5 V, 3.3 V, and 5 V signaling with 5 V input tolerance, reducing the need for external level translation in multi-voltage systems.
• Industrial Temperature Rating: Rated for −40 °C to +85 °C, enabling deployment in temperature-demanding environments.
• Compact Surface-Mount Package: 144-pin LQFP (surface mount) provides a small-footprint solution for space-constrained boards.
• In-System Diagnostics and JTAG: Boundary-scan and in-system verification capabilities aid development, field diagnostics, and manufacturing test.
• RoHS Compliant: Conforms to RoHS requirements for lead-free assembly and compliance-driven programs.
