A54SX32A-TQ144M

The A54SX32A-TQ144M is a Microchip SX-A family field programmable gate array (FPGA) offered in a 144-pin LQFP/TQFP package and specified for military temperature operation. It delivers a nonvolatile, single‑chip FPGA architecture with 48,000 system gates and 2,880 logic elements suitable for control, I/O bridging and deterministic timing applications.

Designed for systems requiring flexible I/O voltage support and extended temperature range, the device provides hot‑swap–compatible I/Os, mixed‑voltage operation and on‑chip security and test features to support robust embedded designs.

Key Features

• Core Capacity — 48,000 system gates and 2,880 logic elements provide significant programmable logic resources for moderate-complexity designs.
• Performance — System performance up to 250 MHz and internal performance up to 350 MHz as specified for the SX-A family.
• I/O Count & Flexibility — 113 user I/O pins with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, enabling interface compatibility across voltage domains.
• Mixed‑Voltage Operation — Supports 2.5 V, 3.3 V and 5 V mixed‑voltage operation with 5 V input tolerance and 5 V drive strength; supply range 2.25 V to 5.25 V.
• System Reliability & Test — Hot‑swap compliant I/Os, power‑up/down friendly operation (no sequencing required), and IEEE‑1149.1 boundary‑scan (JTAG) support for board-level testability.
• Security & In-System Diagnostics — Nonvolatile single‑chip configuration with Actel (SX-A) secure programming technology and in‑system diagnostic and verification capability.
• Package & Mounting — Surface mount device in a 144‑pin LQFP/TQFP (20 × 20) package, RoHS compliant and available in military temperature grade (−55 °C to 125 °C).

Typical Applications

• Military and Rugged Electronics — Military temperature rating and robust packaging make the device suited for high‑reliability controllers and interface logic in harsh environments.
• System I/O Bridging — Configurable I/Os and mixed‑voltage support enable level translation, protocol bridging and peripheral interfaces across 2.5 V, 3.3 V and 5 V domains.
• Deterministic Control Logic — High internal performance and deterministic timing capabilities support real‑time control and timing‑sensitive state machines.
• Board‑Level Test and Repair — Boundary‑scan and in‑system diagnostics assist production test, field diagnostics and firmware verification workflows.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Eliminates the need for external configuration memory, simplifying board design and cold-start behavior.
• Wide I/O Voltage Support: Configurable I/Os and mixed‑voltage operation reduce level‑shifter components and lower BOM for multi‑voltage systems.
• Extended Temperature Range: Military grade specification (−55 °C to 125 °C) enables deployment in demanding thermal environments.
• Built‑In Test and Security: Boundary‑scan (IEEE‑1149.1) and secure programming features provide design protection and support manufacturing test flows.
• Deterministic Performance: Documented system and internal performance figures (250 MHz / 350 MHz) help in designing predictable timing paths.

Why Choose A54SX32A-TQ144M?

The A54SX32A-TQ144M combines a substantial logic resource set (48,000 gates, 2,880 logic elements) with flexible, mixed‑voltage I/Os and military temperature qualification to address embedded designs that require durable, deterministic programmable logic. Its nonvolatile single‑chip architecture and onboard test/security capabilities simplify system integration while supporting production test and in‑field verification.

This device is well suited for engineers building control, interface and timing‑sensitive subsystems where I/O flexibility, extended temperature operation and on‑chip programmability reduce BOM and streamline system qualification.
