A54SX32-1TQG144

The A54SX32-1TQG144 is a member of the SX‑A family of nonvolatile FPGAs from Microchip Technology. This device delivers 48,000 system gates implemented across 2,880 logic elements with 113 user-programmable I/O pins in a 144‑pin LQFP package.

Designed for commercial temperature operation (0 °C to 70 °C) and RoHS‑compliant manufacturing, the A54SX32-1TQG144 supports mixed‑voltage systems with a supply range of 3 V to 5.25 V and provides series-level performance features such as 250 MHz system performance and 350 MHz internal performance.

Key Features

• Core Capacity – 48,000 system gates realized across 2,880 logic elements to implement medium-complexity logic functions and glue‑logic integration.
• Performance – Series specifications include up to 250 MHz system performance and up to 350 MHz internal performance for timing‑sensitive paths.
• I/O and Mixed‑Voltage Support – 113 user I/Os with configurable support for PCI 3.3 V/5 V, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; devices support mixed‑voltage operation and 5 V input tolerance and drive strength at the series level.
• Nonvolatile, Single‑Chip Solution – SX‑A family architecture offers nonvolatile configuration in a single device for simplified power‑up behavior and system design.
• Package and Mounting – Surface‑mount 144‑pin LQFP (supplier package: 144‑TQFP, 20×20) for compact PCB designs.
• Power and Supply – Broad supply range from 3 V to 5.25 V to accommodate common logic domains and mixed‑voltage boards.
• Security and Test – Series features include boundary‑scan (IEEE 1149.1) support and secure programming technology to protect bitstream intellectual property (FuseLock™ referenced at the series level).
• Compliance and Grade – Commercial temperature grade (0 °C to 70 °C) and RoHS‑compliant packaging.

Typical Applications

• PCI‑capable systems – Useful in designs that require 66 MHz PCI compatibility and configurable 3.3 V/5 V I/O signaling.
• Mixed‑voltage interface bridging – Acts as a programmable bridge or I/O translator in systems combining 2.5 V, 3.3 V and 5 V domains thanks to series mixed‑voltage support and 5 V tolerance.
• In‑system diagnostic and verification – Series diagnostic features enable in‑system testing and verification workflows during development and production.
• Boundary‑scan test environments – Supports IEEE 1149.1 boundary‑scan testing at the series level to simplify board‑level test and bring‑up.

Unique Advantages

• Substantial logic capacity: 48,000 system gates and 2,880 logic elements offer a compact, single‑chip platform for medium‑complexity designs.
• Deterministic performance: Series performance characteristics (250 MHz system, 350 MHz internal) provide predictable timing headroom for performance‑sensitive paths.
• Flexible I/O strategy: Configurable I/O standards and mixed‑voltage operation reduce the need for external level translators and lower BOM complexity.
• Nonvolatile configuration: Single‑chip nonvolatile architecture streamlines power‑up behavior and eliminates the need for external configuration memory.
• Test and IP protection: Boundary‑scan support and secure programming technology at the series level help protect designs and enable efficient manufacturing test.
• Commercial deployment ready: Commercial temperature rating and RoHS compliance align the device with a wide range of standard embedded and electronic applications.
