A54SX32A-1PQG208I

The A54SX32A-1PQG208I is an SX-A family FPGA from Microchip Technology. This nonvolatile, single-chip FPGA delivers 48,000 system gates implemented across 2,880 logic elements with 174 user-programmable I/Os in a 208-pin BFQFP surface-mount package.

Engineered for industrial applications, the device supports mixed-voltage I/O, hot-swap compliant pins, and an extended operating range (–40 °C to 85 °C), making it suitable for control, interface, and mixed-signal glue logic in industrial systems and other embedded designs.

Key Features

• Core Capacity — Approximately 48,000 system gates and 2,880 logic elements for implementing medium-complexity logic functions.
• Flip-Flops — Up to 2,012 dedicated flip-flops available for synchronous designs and state storage.
• I/O — 174 user-programmable I/Os with configurable I/O standards and hot-swap compliance to support robust board-level interfacing.
• Performance — SX-A family performance metrics include up to 250 MHz system performance and up to 350 MHz internal performance (family-level data).
• Voltage and I/O Flexibility — 2.25 V to 5.25 V supply range and family support for mixed 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance (series-level feature).
• Nonvolatile Single-Chip Architecture — In-system nonvolatile configuration for retained design data without external configuration memory (SX-A family feature).
• No Embedded RAM — Total on-chip RAM bits: 0; design resources are focused on logic and flip-flop density.
• Package & Mounting — 208-pin BFQFP (supplier device package: 208-PQFP 28×28) in a surface-mount form factor suitable for standard PCB assembly.
• Industrial Grade — Specified for industrial temperature operation from –40 °C to 85 °C and RoHS compliant.
• System and Test Features — Series-level features include boundary-scan (IEEE 1149.1/JTAG) and in-system diagnostic capabilities (Silicon Explorer II support noted in family documentation).

Typical Applications

• Industrial Control — Use where industrial temperature range, 174 I/Os, and nonvolatile configuration support robust control and interface tasks.
• Interface Bridging — Implement protocol adapters and glue logic leveraging the device’s large I/O count and mixed-voltage I/O capability.
• Embedded System Logic — Suitable for medium-complexity state machines, control logic, and timing-critical functions using available flip-flops and logic elements.
