Key Features

• Logic Capacity — 48,000 system gates implemented as 2,880 logic elements (combinatorial cells and registers) to support moderate complexity digital designs.
• High Performance — Documented system performance up to 250 MHz and internal performance up to 350 MHz for timing‑sensitive logic paths.
• I/O Flexibility — 249 user I/Os with configurable support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; 5 V input tolerance and 5 V drive strength are supported as specified in the family datasheet.
• Nonvolatile Single‑Chip Configuration — Single‑chip, nonvolatile architecture eliminates the need for external configuration memory and preserves configuration across power cycles.
• Power and I/O Safety — Hot‑swap compliant I/Os and power‑up/power‑down friendly operation with no supply sequencing required per the SX‑A family documentation.
• Security and Testability — Actel Secure Programming Technology (FuseLock™) to guard against reverse engineering and boundary‑scan testing compliant with IEEE 1149.1 (JTAG) for board‑level diagnostics.
• Package and Mounting — 484‑ball Fine‑Pitch BGA (484‑FPBGA, 27×27 mm) in a surface‑mount form factor; RoHS compliant packaging available.
• Voltage and Temperature — Supply voltage range 2.25 V to 5.25 V and commercial operating temperature 0 °C to 70 °C as specified for this part number.
• Clocking — Device supports three global clocks as defined for the A54SX32A in the SX‑A family documentation.
• Resource Utilization — Family documentation notes support for up to 100% resource utilization and 100% pin locking for deterministic designs.
• On‑chip RAM — Total on‑chip RAM reported as 0 bits for this device (no embedded RAM).

Typical Applications

• Commercial Embedded Systems — Single‑chip nonvolatile FPGA with flexible I/O and mixed‑voltage support for consumer and commercial embedded control and interface tasks.
• I/O‑Intensive Peripheral Interfaces — High I/O count (249 pins) and 5 V tolerance enable bridging and interfacing to legacy peripherals, sensors, and external logic.
• PCI and Bus Bridging — SX‑A family documentation lists 66 MHz PCI compliance and configurable 3.3 V/5 V PCI I/O support suited to legacy bus interface implementations.
• In‑System Diagnostics and Verification — Built‑in support for in‑system diagnostic and verification via Silicon Explorer II as referenced in the SX‑A family documentation.

Unique Advantages

• Nonvolatile Single‑Chip Configuration: Eliminates external configuration components and simplifies BOM and board design.
• Mixed‑Voltage I/O with 5 V Tolerance: Reduces the need for level‑shifters when interfacing with diverse peripheral voltage domains.
• Security‑Oriented Programming: FuseLock™ programming technology protects design IP against reverse engineering.
• Power‑Friendly I/Os: Hot‑swap compliance and power‑up/power‑down friendly behavior simplify system power sequencing.
• Deterministic Timing and Full Resource Utilization: Family features support deterministic, user‑controllable timing and high resource utilization for tight design control.
• Commercial Temperature Optimization: Designed and specified for commercial temperature operation (0 °C to 70 °C) for mainstream electronics applications.
