• Core capacity  Approximately 48,000 system gates and 2,880 logic elements, supporting designs with medium logic density requirements.
• User I/O  113 user-programmable I/O pins with configurable weak pull-up/pull-down and individual output slew control for interface flexibility.
• Performance  SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance.
• Nonvolatile single-chip solution  On-chip nonvolatile configuration removes the need for separate configuration memory and supports power-up/power-down friendly operation.
• Mixed-voltage and 5 V tolerance  Configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, enabling mixed-voltage system designs.
• System integration and test  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability with Silicon Explorer II.
• Security  Actel Secure Programming Technology with FuseLock™ to protect design IP and prevent reverse engineering.
• Package and mounting  144-LQFP / supplier 144-TQFP (20 × 20 mm) package, surface-mount mounting type; RoHS compliant.
• Rugged temperature range  Designed for military temperature grade operation from −55 °C to 125 °C.
• Voltage supply  Operates from 3 V to 5.5 V to accommodate a range of system power rails.

Typical Applications

• Military and aerospace control  Suitable for control and signal-processing functions that require military-grade temperature performance and RoHS compliance.
• Mixed-voltage interface bridging  Used to implement protocol translation and interface logic where 5 V and 3.3 V signalling coexist, leveraging the configurable I/O and 5 V tolerance.
• Deterministic logic and timing subsystems  Applicable where predictable timing and in-system diagnostics (JTAG, Silicon Explorer II) are required for validation and fault isolation.
• Nonvolatile programmable logic  Ideal for systems that benefit from a single-chip, nonvolatile FPGA solution to avoid external configuration memory and simplify power-up behavior.

Unique Advantages

• Military-grade thermal resilience: Rated for −55 °C to 125 °C to meet demanding environmental requirements.
• Nonvolatile single-chip architecture: Eliminates separate configuration memory, simplifying board-level design and power sequencing.
• Flexible mixed-voltage I/O: Configurable support for multiple I/O standards and 5 V tolerance eases integration with legacy and modern logic families.
• On-board security features: FuseLock™ secure programming protects design IP and helps prevent reverse engineering.
• Deterministic performance and diagnostics: Documented system and internal performance figures plus JTAG and in-system diagnostic capabilities speed development and validation.
• Compact, surface-mount packaging: 144-LQFP / 144-TQFP (20 × 20) enables high-density PCB layouts while maintaining ample I/O count.
