• Performance (Family)  SX-A family performance specifications include up to 250 MHz system performance and up to 350 MHz internal performance.
• Robust Power and I/O Behavior  Power-up/down friendly operation (no sequencing required for supply voltages) and hot-swap compliant I/Os simplify integration into complex power domains.
• Packaging and Mounting  256-pin fine-pitch BGA (17×17) in a surface-mount package suited to high-density PCB layouts.
• Wide Supply and Temperature Range  Operates from 2.25 V to 5.25 V and rated for military temperature grade operation from −55°C to 125°C.
• Design and Test Support  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic and verification capability are provided by the SX-A family tools.

Typical Applications

• Aerospace & Defense Systems  Military temperature grade and robust packaging make the A54SX32A-FGG256M suitable for avionics and defense electronics requiring reliable programmable logic in harsh environments.
• Rugged Industrial Control  Mixed-voltage I/O and wide supply tolerance enable integration into industrial control systems and factory automation where board-level flexibility is required.
• Secure Embedded Systems  Nonvolatile single-chip configuration and secure programming features help protect intellectual property in secure communications and mission-critical designs.
• Interface Bridging and Legacy Support  Configurable I/Os and family-level PCI support allow the device to implement protocol adaptation and board-level interface logic.

Unique Advantages

• High Integration Density: 48,000 system gates and 2,880 logic elements reduce external components and simplify board-level designs.
