• I/O Density & Flexibility  175 user-programmable I/O pins supported in the 208-pin package; configurable I/O supports 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 levels per the SX-A family specification.
• Mixed-Voltage Operation  Supports 2.5 V, 3.3 V and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength as documented for the SX-A family.
• Nonvolatile Single-Chip Solution  On-chip nonvolatile configuration removes the need for external configuration memory, simplifying board-level design and startup behavior.
• Power & I/O Robustness  Hot-swap–compliant I/Os and power-up/power-down friendly operation with no sequencing required for supply voltages.
• Performance  SX-A family performance targets listed at up to 250 MHz system performance and up to 350 MHz internal performance (family values).
• Security & Test  Actel Secure Programming Technology with FuseLock™ and IEEE 1149.1 (JTAG) boundary-scan support for device security and testability.
• Package & Supply  208-pin BFQFP (supplier references 208-PQFP 28×28); voltage supply range 2.25 V to 5.25 V; commercial temperature grade 0 °C to 70 °C.
• Standards Compatibility  66 MHz PCI compliant as specified in the SX-A family datasheet.
• RoHS Compliance  Device is RoHS compliant.

Typical Applications

• PCI-compliant add-on cards  Use the device where 66 MHz PCI compatibility and configurable 3.3 V / 5 V I/O support are required for peripheral interfacing.
• Mixed-voltage system glue  Bridge logic domains and implement interface translation in systems with 2.5 V, 3.3 V and 5 V signaling, leveraging 5 V input tolerance and configurable I/O.
• Embedded logic with secure configuration  Deploy as a nonvolatile programmable logic element in embedded systems that benefit from on-chip secure programming (FuseLock™) and in-system verification capabilities.

Unique Advantages

• Single-chip nonvolatile configuration: Eliminates the need for external configuration memory, reducing BOM and simplifying board design.
• Flexible I/O voltage support: Configurable I/O standards and mixed-voltage operation enable simple interfacing across legacy and modern logic levels.
• Hot-swap and power-up robustness: Hot-swap–compliant I/Os and power-up/power-down friendly behavior reduce system sequencing complexity.
• Security and testability: FuseLock™ secure programming and IEEE 1149.1 JTAG boundary-scan improve IP protection and production test capability.
• Moderate gate density with high I/O count: 24,000 system gates and 175 I/Os in a 208-pin package balance logic capacity and connectivity for mid-range designs.
• RoHS compliant: Meets environmental restrictions for lead-free assembly and regulatory alignment.
