A54SX32-1BG329I

The A54SX32-1BG329I is an industrial-grade SX family FPGA from Microchip Technology designed for deterministic logic implementation in compact, surface-mount form factors. It provides a balance of logic capacity, high I/O density and configurable mixed-voltage I/O to support control, interface and protocol tasks in industrial and embedded systems.

This device targets applications that require up to 48,000 system gates and 249 user I/Os in a 329-ball BGA package, offering nonvolatile single‑chip configuration and a broad operating voltage and temperature window for reliable deployment in industrial environments.

Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements provide the resources to implement medium-complexity state machines, glue logic and protocol acceleration.
• I/O and Mixed-Voltage Support — 249 user-programmable I/Os with configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; supports mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance — Family-level performance specifications include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Nonvolatile Single-Chip Configuration — Built-in nonvolatile configuration reduces external components needed for device configuration at power-up.
• Power and I/O Robustness — Hot-swap compliant I/Os and power‑up/power‑down friendly operation with no supply sequencing required simplify board-level power management.
• Test and Debug — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic capability with Silicon Explorer II.
• Security — Actel Secure Programming Technology with FuseLock™ provides protection against reverse engineering and unauthorized readback.
• Package and Mounting — 329-ball BGA (329-BBGA / supplier package 329-PBGA 31×31) in a surface-mount package for high-density PCB designs.
• Industrial Temperature and Supply Range — Rated for industrial temperature operation (−40 °C to 85 °C) with supply range listed at 3 V to 5.5 V.

Typical Applications

• Industrial Control — Implement programmable state machines, timing logic and I/O aggregation for factory automation and motion control systems.
• Interface Bridging — Use high I/O count and mixed-voltage support to bridge disparate interfaces and implement protocol conversion between 2.5 V, 3.3 V and 5 V domains.
• Embedded System Glue Logic — Offload glue logic, reset sequencing, and custom peripheral control to a single nonvolatile FPGA to reduce BOM count.
• Test & Diagnostic Hardware — Leverage boundary-scan and in-system diagnostics for board-level validation and field troubleshooting.

Unique Advantages

• High I/O Density: 249 user I/Os provide extensive external connectivity without resorting to larger, more expensive packages.
• Flexible Voltage Interfacing: Configurable I/O standards and mixed-voltage operation simplify integration with legacy 5 V logic and modern lower-voltage peripherals.
• Nonvolatile Configuration: Single‑chip nonvolatile storage removes the need for external configuration memory and simplifies system boot.
• Industrial Ready: Specified operation from −40 °C to 85 °C and surface-mount BGA packaging support deployment in industrial environments.
• Security and Testability: FuseLock programming protection and IEEE‑1149.1 boundary-scan support help protect IP and streamline manufacturing test.
• Deterministic Timing: User-controllable timing resources enable predictable performance for time-critical designs.

Why Choose A54SX32-1BG329I?
