• Performance  SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family specifications).
• Nonvolatile Configuration & Security  Nonvolatile, single‑chip solution with Actel Secure Programming Technology including FuseLock™ to help protect design IP and prevent reverse engineering.
• System Reliability & Test  Power‑up/down friendly operation with no supply sequencing required, hot‑swap compliant I/Os, and IEEE 1149.1 (JTAG) boundary‑scan testing support for board‑level testability.
• Diagnostics & Development  Unique in‑system diagnostic and verification capability with Silicon Explorer II (family tool referenced in datasheet) to aid debug and validation.
• Power & Voltage  Wide supply voltage range of 2.25 V to 5.25 V to accommodate mixed‑voltage systems and flexible board designs.
• Package & Temperature  208‑pin BFQFP (supplier device package listed as 208‑PQFP, 28×28) in a surface‑mount package and rated for industrial temperature operation from −40 °C to 85 °C.
• Standards & Interfaces  66 MHz PCI compliance noted for the SX-A family for designs requiring legacy PCI interface compatibility.

Typical Applications

• PCI and interface bridging  Supports 66 MHz PCI‑compliant signaling and configurable 3.3 V/5 V I/O, enabling use on PCI add‑in cards and interface bridging modules.
• Industrial embedded systems  Industrial temperature grading (−40 °C to 85 °C) and wide supply range make the device suitable for industrial control, instrumentation, and automation designs requiring robust operation.
• High‑density glue logic and I/O aggregation  With 108,000 system gates and 171 I/Os, the device is well suited for consolidating glue logic, protocol translation, and dense I/O routing in space-constrained PCBs.
• In‑system verification and diagnostic roles  Nonvolatile configuration and Silicon Explorer II support enable designs that benefit from in‑field diagnostics and verification capabilities.

Unique Advantages

• High logic density:  108,000 system gates and 6,036 logic elements provide the capacity to implement complex logic and control functions on a single device.
• Flexible I/O signaling:  Configurable support for multiple voltage standards and 5 V tolerance/drive strength reduces the need for level translators and simplifies mixed‑voltage system designs.
• Nonvolatile, single‑chip solution:  On‑chip nonvolatile configuration removes the need for external configuration memory and streamlines board design.
• Industrial readiness:  Industrial temperature rating and a 2.25–5.25 V supply range enable deployment in demanding embedded environments.
• Built‑in test and diagnostics:  Boundary‑scan (IEEE 1149.1) support and in‑system diagnostic capability aid manufacturing test and field troubleshooting.
• Secure programming:  FuseLock™ technology protects bitstream confidentiality and helps prevent reverse engineering of the programmed design.
