A54SX32A-PQG208M

The A54SX32A-PQG208M is a member of the SX-A family of nonvolatile FPGAs from Microchip Technology. It combines a single-chip, nonvolatile architecture with configurable, mixed-voltage I/O and deterministic timing features drawn from the SX-A family specification.

Designed for military-grade applications, the device provides a balance of logic capacity, I/O density and rugged operating conditions for embedded systems that require secure programming, boundary-scan testability and predictable performance.

Key Features

• Core Capacity — 48,000 system gates and 2,880 logic elements provide substantial programmable logic for mid-density designs.
• I/O Count & Configurability — 174 user-programmable 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 mixed-voltage interfacing.
• Performance — SX-A family performance characteristics include 250 MHz system performance and up to 350 MHz internal performance as specified for the family.
• Nonvolatile Single-Chip Solution — SX-A family nonvolatile architecture eliminates external configuration memory and supports secure programming features, including FuseLock™ technology.
• Flip-Flops and Logic Resources — Family-level support for up to 2,012 dedicated flip-flops and deterministic, user-controllable timing.
• Power & Voltage — Operates across a wide supply range (2.25 V to 5.25 V) and supports mixed-voltage operation with 5 V input tolerance and 5 V drive strength; power-up/power-down friendly with no supply sequencing required.
• Package & Mounting — 208-pin BFQFP (supplier device package: 208-PQFP, 28×28) in a surface-mount mount style suitable for high-reliability assembly.
• Temperature & Grade — Military grade device with an operating temperature range of −55 °C to +125 °C.
• Test & Diagnostics — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic and verification capability as specified for the SX-A family.
• Embedded Memory — No on-chip RAM (Total RAM Bits: 0), simplifying deterministic timing and resource planning.
• Regulatory — RoHS compliant.

Typical Applications

• Military and Aerospace Systems — Military temperature grade and wide operating range make the device suitable for rugged embedded control, mission electronics and avionics logic functions.
• PCI and Legacy Interface Gateways — 66 MHz PCI compliance and configurable I/O levels enable integration into PCI-based systems and mixed-voltage interface bridging.
• High-Reliability Embedded Control — Nonvolatile single-chip architecture, deterministic timing and power-up/power-down friendliness suit high-reliability control and sequencer designs.
• Secure Systems and On-Board Diagnostics — Secure programming (FuseLock) and the SX-A family’s in-system diagnostic capabilities support designs requiring design protection and on-board verification.

Unique Advantages

• Military-Grade Reliability: Rated for −55 °C to +125 °C and supplied in a 208-pin surface-mount package to meet rugged application requirements.
• Nonvolatile, Single-Chip FPGA: Eliminates external configuration memory and simplifies system boot and security considerations.
• Wide Voltage Flexibility: 2.25 V to 5.25 V supply range and mixed-voltage I/O support reduce the need for external level shifters and streamline board-level power design.
• Deterministic Timing: SX-A family timing architecture supports predictable, user-controllable timing for latency-sensitive designs.
• Built-In Test and Security: Boundary-scan (IEEE 1149.1) plus family-level secure programming and in-system diagnostic features improve testability and protect IP.
• Substantial Logic Density: 48,000 gates and 2,880 logic elements provide the capacity for mid-density logic integration while avoiding external CPLD/FPGA partitioning.
