A54SX32A-FTQ144

The A54SX32A-FTQ144 is a commercial-grade FPGA from the SX‑A family by Microchip Technology. It implements a nonvolatile, single-chip SX‑A architecture delivering 48,000 system gates with 2,880 logic elements and 113 user I/Os in a 144-pin LQFP package.

Designed for mixed-voltage systems, the device supports a wide supply range (2.25 V to 5.25 V) and operates over a commercial temperature range (0 °C to 70 °C). SX‑A family characteristics provide features useful for PCI-compliant interfaces, in-system programmability, and board-level I/O flexibility.

Key Features

• Core Capacity — 48,000 system gates and 2,880 logic elements deliver a mid-range FPGA resource set appropriate for control, glue logic, and interface tasks.
• User I/O — 113 user-programmable I/Os in the 144-pin LQFP package enable flexible board-level interfacing across multiple signals.
• Voltage and I/O Flexibility — Supports mixed-voltage operation (2.5 V, 3.3 V, and 5 V) with a device supply range from 2.25 V to 5.25 V; configurable I/O support for common standards and 5 V input tolerance are provided by the SX‑A family.
• Performance — SX‑A family data indicates up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Nonvolatile, In-System Programmability — Single-chip nonvolatile configuration allows in-system programming and reconfiguration without external configuration memory.
• Power and Reliability Features — Hot-swap–compliant I/Os and power-up/power-down–friendly behavior (no sequencing required for supply voltages) simplify system power management.
• Security and Testability — Family features include boundary-scan (IEEE 1149.1) support and secure programming technology to help protect design IP.
• Package and Grade — Surface-mount 144-LQFP package (supplier device package listed as 144-TQFP 20×20) and commercial temperature grade (0 °C to 70 °C).
• Memory — Total on-chip RAM bits: 0 (no embedded RAM reported for this device).

Typical Applications

• PCI and Bus Interface Logic — Implement PCI-compliant interface functions and bus-bridging logic where 66 MHz PCI compatibility and mixed-voltage I/O support are required.
• Board-Level Glue and I/O Bridging — Replace discrete glue logic for signal conditioning and level translation across 2.5 V, 3.3 V, and 5 V domains.
• Embedded Control and Peripheral Interfaces — Implement control state machines, protocol adapters, and peripheral interface logic using the device’s logic elements and abundant I/O.
• Production Test and In-System Diagnostics — Use boundary-scan and in-system diagnostic capabilities from the SX‑A family to streamline manufacturing test and field diagnostics.

Unique Advantages

• Flexible Mixed-Voltage Support: Wide supply range (2.25 V–5.25 V) and configurable I/O standards enable seamless integration with legacy and modern logic levels.
• Nonvolatile Single-Chip Solution: Eliminates the need for external configuration memory, simplifying BOM and board layout while preserving in-system programmability.
• Robust I/O and Power Behavior: Hot-swap-compliant I/Os and power-up/power-down friendliness reduce system-level power sequencing constraints and improve resilience during board-level events.
• Testability and IP Protection: Boundary-scan support and secure programming technology help protect designs and support manufacturing test flows.
• Well-Matched Resource Set: 48,000 system gates with 2,880 logic elements and 113 I/Os provide a balanced mix of logic and I/O for mid-range embedded designs.
