A54SX32A-2FG484

The A54SX32A-2FG484 is a commercial-grade member of the SX-A family of nonvolatile FPGAs. It delivers a mid-range logic capacity with 48,000 system gates and 2,880 logic elements in a 484‑ball fine-pitch BGA package targeted at embedded control, interface, and I/O‑dense applications.

Built for mixed-voltage system environments, the device combines high I/O density (249 user I/Os) with in-system programmability, boundary-scan support and security features to simplify integration and protect designs.

Key Features

• Logic Capacity  Approximately 48,000 system gates and 2,880 logic elements for mid-range digital logic integration.
• I/O Density & Flexibility  249 user-programmable I/Os with hot-swap compliant I/Os and configurable pull-up/pull-down at power-up to support complex board-level interfacing.
• Performance  SX-A family published performance metrics include up to 250 MHz system performance and up to 350 MHz internal performance (family values).
• Voltage & I/O Standards  Supports mixed-voltage operation (2.5 V, 3.3 V, and 5 V) with 5 V input tolerance and 5 V drive strength; datasheet documents configurable I/O for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2.
• Power Supply  Device supply range: 2.25 V to 5.25 V to accommodate a variety of system power rails.
• Nonvolatile Single-Chip Architecture  SX-A family devices are provided as nonvolatile, single-chip FPGAs—eliminating the need for external configuration memory.
• Security & Test  Actel Secure Programming Technology with FuseLock™ for design protection and IEEE 1149.1 boundary-scan (JTAG) for board-level testability.
• Deterministic Timing & Utilization  Datasheet documents deterministic, user-controllable timing plus support for up to 100% resource utilization and 100% pin locking.
• Package & Mounting  484‑BGA package (supplier device package: 484‑FPBGA, 27 × 27 mm); surface-mount mounting type.
• Commercial Grade  Grade: Commercial with operating temperature range 0 °C to 70 °C and RoHS compliant packaging.
• Embedded Memory  Total RAM bits: 0 (no on-chip RAM reported for this device).

Typical Applications

• PCI and Legacy Interface Logic  PCI-compliant signaling capability and configurable I/O standards make the device suitable for interface bridging and legacy bus logic.
• Embedded Control & Glue Logic  Mid-range gate count and high I/O density support aggregation of control functions and system glue logic into a single nonvolatile device.
• Board-Level Test & Secure Configuration  Boundary-scan and FuseLock secure programming simplify manufacturing test and protect intellectual property on deployed boards.

Unique Advantages

• High I/O Count: 249 user I/Os enable dense peripheral and bus connectivity without external I/O expanders.
• Mixed-Voltage Support: Broad mixed-voltage operation and 5 V tolerance simplify interfacing to both legacy 5 V logic and modern 2.5/3.3 V domains.
• Nonvolatile Single-Chip Solution: Removes the need for external configuration memory, reducing BOM and simplifying board design.
• Design Security: FuseLock secure programming technology helps protect against reverse engineering and unauthorized cloning.
• Deterministic Timing: User-controllable timing and support for full resource utilization aid predictable system integration and timing closure.
• Commercial and RoHS Compliant: Commercial grade with RoHS‑compliant packaging for standard commercial product deployments.

Why Choose A54SX32A-2FG484?

The A54SX32A-2FG484 balances mid-level logic capacity (48k system gates, 2,880 logic elements) with high I/O density (249 pins) in a compact 484‑ball FBGA. Its nonvolatile single-chip architecture, mixed-voltage I/O flexibility, and family-level performance figures make it well suited for system designers consolidating interface, control, and glue logic while retaining secure in-field configuration.

For commercial embedded applications that require dense I/O, secure programming, and board-level testability within a 0 °C to 70 °C operating range, this device offers a practical combination of integration, configurability, and ecosystem-level features documented in the SX-A family datasheet.
