A54SX32A-FGG484

The A54SX32A-FGG484 is a member of the SX-A family of nonvolatile FPGAs. It provides a mid-range logic capacity and dense I/O in a 484-ball fine-pitch BGA package, suited for commercial embedded and board-level applications requiring reprogrammable logic and configurable I/O.

Designed for single-chip, nonvolatile operation, this device combines 48,000 system gates with 2,880 logic elements and up to 249 user I/Os, delivering deterministic timing and family-level performance characteristics for system and interface control tasks.

Key Features

• Logic Capacity  48,000 system gates and 2,880 logic elements provide mid-range programmable logic resources for combinational and sequential logic implementation.
• High-density I/O  Up to 249 user I/Os allow extensive peripheral and bus interfacing directly from the FPGA package.
• Performance  Family datasheet specifies system performance up to 250 MHz and internal performance up to 350 MHz for timing-critical paths.
• Configurable I/O Standards  Supports configurable I/O for multiple voltage standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 with 5 V input tolerance and 5 V drive strength.
• Nonvolatile Single-Chip Solution  On-chip nonvolatile configuration enables single-chip operation without external configuration memory.
• Power and I/O Robustness  Hot-swap compliant I/Os and power-up/down friendly operation (no sequencing required for supply voltages) simplify system power management.
• Package and Mounting  484-ball fine-pitch BGA (484-FPBGA, 27×27 mm) surface-mount package for compact board layouts and dense routing.
• Voltage and Temperature  Supports a supply range of 2.25 V to 5.25 V and is specified for commercial temperature operation from 0 °C to 70 °C.
• Test, Security and Diagnostics  Boundary-scan testing (IEEE 1149.1/JTAG), in-system diagnostic capability, and Actel Secure Programming Technology (FuseLock™) for design protection.

Typical Applications

• PCI and Bus Interface Logic  Use the configurable 3.3 V/5 V PCI support and 66 MHz PCI compliance for implementing PCI interface glue logic and protocol bridging.
• Embedded Control  Implement system control, protocol translation, and board-level arbitration tasks using the device’s logic capacity and abundant I/Os.
• Peripheral and I/O Expansion  Provide dense, reprogrammable I/O handling for sensor aggregation, display/control front-ends, or custom peripheral interfaces.
• In-System Diagnostics and Test  Leverage built-in boundary-scan and in-system diagnostic features for manufacturing test and field verification workflows.

Unique Advantages

• Balanced Logic and I/O Density: 48,000 system gates with 2,880 logic elements and 249 I/Os deliver a practical balance of resources for mid-range designs.
• Flexible Voltage Support: Wide supply range (2.25–5.25 V) and multi-standard I/O support simplify integration with mixed-voltage boards and legacy interfaces.
• Nonvolatile Configuration: Single-chip nonvolatile operation removes the need for external configuration components for on-power-up configuration.
• Robust I/O Behavior: Hot-swap compliance and power-up/down friendly I/Os reduce board-level power sequencing complexity.
• Security and Testability: FuseLock™ programming and IEEE 1149.1 boundary-scan provide mechanisms for design protection and standard test access.
• Compact, Surface-Mount Package: 484-FPBGA (27×27 mm) packaging enables high-density PCB layouts while supporting extensive I/O.
