A54SX32A-1TQG100M

The A54SX32A-1TQG100M is a Microchip Technology SX-A family FPGA in a 100-pin LQFP surface-mount package. It delivers a nonvolatile, single‑chip programmable logic solution with 48,000 system gates and 2,880 logic elements, and exposes 81 user I/O pins for mixed‑signal interfacing.

Designed for military-grade applications, this device supports a wide operating range (2.25 V to 5.25 V supply and –55 °C to 125 °C operation) and includes family-level features such as high internal performance and configurable I/O to address system‑level integration and secure programmable logic needs.

Key Features

• Programmable Logic Capacity — 48,000 system gates and 2,880 logic elements provide substantial gate count for glue logic, protocol bridging, and control functions.
• User I/O — 81 user-programmable I/Os suitable for mixed‑voltage interfacing and board-level connectivity.
• Performance (SX-A Family) — Family-level performance indicators include up to 250 MHz system performance and 350 MHz internal performance.
• Nonvolatile Single-Chip Architecture — A single-chip, nonvolatile FPGA architecture removes the need for external configuration memory.
• Flexible I/O and Mixed-Voltage Support — Configurable I/O supporting multiple voltage standards and 5 V input tolerance with selectable drive strength and individual output slew control.
• Security and Test — Built‑in security programming technology (FuseLock™) to protect design IP and IEEE 1149.1 (JTAG) boundary-scan support for board-level testing.
• In-System Diagnostics — Family-level support for in-system diagnostic and verification capability (Silicon Explorer II).
• Robust Power Behavior — Hot-swap compliant I/Os and power-up/power-down friendly operation without sequencing requirements.
• Package and Mounting — 100‑pin LQFP package (supplier device package: 100‑TQFP 14×14) for surface-mount applications.
• Military Temperature Grade — Specified operating temperature range of –55 °C to 125 °C for high-reliability, rugged environments.
• No Embedded RAM — Total on‑chip RAM bits: 0; design uses dedicated flip‑flops and logic elements for state storage.

Typical Applications

• Military & Aerospace Embedded Systems — Programmable logic for rugged, temperature-critical control, data routing, and custom processing tasks where military-grade components are required.
• Secure and Hardened Designs — Use FuseLock™ security and nonvolatile configuration to protect intellectual property and prevent reverse engineering.
• Interface Bridging and System Glue — Mixed-voltage I/O and PCI family compliance capabilities make the device suitable for protocol translation and board-level glue logic.
• In-System Test and Verification — Boundary-scan (JTAG) and in-system diagnostic support enable enhanced manufacturing testability and field verification.

Unique Advantages

• High Logic Density: 48,000 system gates and 2,880 logic elements provide ample capacity for complex glue logic and moderate-sized programmable functions.
• Single-Chip Nonvolatile Solution: Eliminates external configuration memory, simplifying BOM and reducing system-level points of failure.
• Wide Voltage Flexibility: 2.25 V to 5.25 V supply range with configurable I/O and 5 V tolerance enables integration across mixed-voltage systems.
• Military-Grade Reliability: –55 °C to 125 °C operating range and military grade classification support deployment in harsh environments.
• Security and Testability: FuseLock™ programming protection plus IEEE 1149.1 boundary-scan and in-system diagnostics help secure IP and streamline testing.
• Power and I/O Robustness: Hot-swap compliant I/Os and power-up/power-down friendly behavior reduce system power sequencing constraints.

Why Choose A54SX32A-1TQG100M?

The A54SX32A-1TQG100M positions itself as a durable, nonvolatile FPGA option for designs that require military-grade temperature performance, flexible mixed-voltage I/O, and a mid-range logic capacity (48,000 system gates, 2,880 logic elements). Its single-chip architecture and security features reduce system complexity while providing deterministic timing and in-system diagnostics for verification and test.

This device is well suited to engineers building rugged embedded systems, secure programmable logic functions, and board-level interface solutions where robust power behavior, testability, and protection of design IP are priorities.
