A54SX72A-1FG484I

The A54SX72A-1FG484I is an SX-A family nonvolatile FPGA offering 108,000 system gates and 6,036 logic elements in a 484-ball fine-pitch BGA package. Designed for industrial-temperature operation, this device provides a mix of high I/O density (up to 360 user-programmable I/Os), configurable mixed-voltage I/O support, and deterministic timing for embedded and system-level logic implementation.

This single-chip, nonvolatile FPGA is targeted at designs that require substantial gate capacity and flexible I/O signaling across 2.25 V to 5.25 V supply ranges while maintaining industrial temperature range operation (–40 °C to +85 °C).

Key Features

• Core capacity and logic — 108,000 system gates with 6,036 logic elements (combinatorial cells) and up to 2,012 dedicated flip-flops, delivering substantial logic resources for complex designs.
• I/O density and configurability — Up to 360 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 signaling; supports mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance and timing — 250 MHz system performance and up to 350 MHz internal performance with deterministic, user-controllable timing suitable for synchronous system designs.
• Power and reliability — Nonvolatile single-chip architecture; power-up/power-down friendly (no sequencing required for supply voltages) and hot-swap compliant I/Os to support robust power management and board-level integration.
• Package and mounting — 484-FPBGA (27×27) fine-pitch BGA package, surface-mount mounting, optimized for high I/O density and compact board integration.
• Temperature and grade — Industrial temperature grade with operating range from –40 °C to +85 °C.
• Security and test — Support for boundary-scan (IEEE 1149.1) for board-level testing and Actel Secure Programming Technology (FuseLock) to protect bitstream confidentiality and prevent reverse engineering.
• Diagnostics and development — In-system diagnostic and verification capability via Silicon Explorer II (as provided for the SX-A family) to aid debugging and validation.
• Memory — Device reports no embedded RAM bits (Total RAM Bits: 0).

Typical Applications

• Industrial control — Implement custom logic, I/O translation and control functions across a wide operating temperature range with robust, power-friendly I/O behavior.
• High-density I/O systems — Use the 360 user-programmable I/Os for board-level glue logic, protocol bridging, and multi-signal interfacing where mixed-voltage signaling is required.
• PCI-based or legacy interface designs — Integrate with 3.3 V / 5 V PCI signaling and 66 MHz PCI-compliant interfaces where nonvolatile configuration and deterministic timing are needed.
• In-system verification and secure designs — Leverage in-system diagnostics and FuseLock programming to protect intellectual property and simplify field validation.

Unique Advantages

• High gate and logic density: 108,000 system gates and 6,036 logic elements provide ample resources for large finite-state machines, glue logic and control fabrics without external logic expansion.
• Flexible, mixed-voltage I/O: Configurable I/Os that support multiple voltage standards and tolerate 5 V inputs reduce the need for level shifters and simplify board design.
• Nonvolatile, single-chip solution: Eliminates external configuration memory and reduces BOM while providing predictable power-up behavior (no supply sequencing required).
• Industrial-grade operation: Rated for –40 °C to +85 °C and supplied in a compact 484-FPBGA surface-mount package suitable for dense, reliable assemblies.
• Built-in test and security: Boundary-scan support and FuseLock programming help secure designs and accelerate manufacturing test and field diagnostics.
