• I/O and Clocking Up to 171 user-programmable I/O pins in the 208-pin PQFP package, with three global clocks and four quadrant clocks for flexible clock distribution.
• Performance System performance up to 250 MHz and internal performance up to 350 MHz as specified for the SX-A family.
• Voltage and I/O Flexibility Supports mixed-voltage operation from 2.5 V, 3.3 V and 5 V ranges with 5 V input tolerance and selectable I/O standards and drive strength; overall supply range 2.25 V to 5.25 V.
• Nonvolatile Single-Chip Solution On-chip nonvolatile configuration removes the need for an external configuration memory device.
• System and Power-Friendly I/Os Hot-swap–compliant I/Os and power-up/power-down friendly operation that does not require sequencing of supply voltages.
• Security and Test Family features include Actel Secure Programming Technology (FuseLock™) to protect bitstream IP and IEEE 1149.1 (JTAG) boundary-scan support for board-level testability.
• Package and Compliance 208-pin plastic quad flat pack (PQFP) surface-mount package; RoHS compliant and specified for commercial temperature operation (0 °C to +70 °C).
• Memory No on-chip embedded RAM (Total RAM bits: 0), delivering a logic-focused resource profile for glue logic and I/O-centric applications.

Typical Applications

• Mixed-Voltage Interface Control Reconfigurable I/O support for 5 V, 3.3 V and 2.5 V interfaces makes the device suitable for bridging and level-shifting tasks in commercial systems.
• PCI-Capable Logic With 66 MHz PCI compliance noted for the SX-A family, the device can be used for PCI-related glue logic and interface functions.
• Embedded System Glue Logic Compact, nonvolatile FPGA for replacing multiple discrete components in commercial embedded designs requiring reprogrammable logic.
• Secure, In-System Programmable Designs Use the device where in-field reconfiguration with bitstream protection and JTAG testability are required.

Unique Advantages

• Nonvolatile, single-chip configuration: Eliminates external configuration memory and simplifies BOM and board-level design.
• Flexible mixed-voltage I/Os: Configurable I/O standards and 5 V input tolerance allow direct interfacing to a wide range of commercial logic levels.
• High logic density in PQFP package: 108,000 system gates and ~6,036 logic elements in a 208-pin package provide significant integration for compact designs.
• Deterministic timing and clock resources: Dedicated global and quadrant clocks enable predictable timing architectures for synchronous designs.
• Security and testability: FuseLock™ programming protection and IEEE 1149.1 boundary-scan support improve IP protection and production test coverage.
• Commercial temperature and RoHS compliance: Designed for commercial-grade deployments (0 °C to +70 °C) and RoHS-compliant materials and packaging.
