• I/O Count & Configurability – 113 user I/Os in the 144-pin package; I/Os are configurable for multiple standards to support mixed-voltage designs and interface flexibility.
• Voltage Supply & Mixed-Voltage Support – Operates from 2.25 V to 5.25 V and supports 2.5 V, 3.3 V, and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance – Family-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical functions.
• Nonvolatile, Single-Chip Solution – Built-in nonvolatile configuration removes the need for external configuration memory and simplifies power-up behavior.
• Security & Protection – Includes Actel Secure Programming Technology with FuseLock™ to protect bitstream confidentiality and prevent reverse engineering.
• Testability & Diagnostics – Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability with Silicon Explorer II.
• Package & Mounting – 144-LQFP surface-mount package (supplier package 144-TQFP, 20×20) for compact PCB integration.
• Commercial Temperature & RoHS – Rated for 0 °C to 70 °C operation and RoHS compliant.

Typical Applications

• Mixed-Voltage Interface and Glue Logic – Configurable I/Os with 5 V tolerance and mixed-voltage operation enable level translation and protocol adaptation between disparate subsystems.
• PCI-Compatible Interface Logic – Supports 66 MHz PCI signaling and can be used to implement PCI-related glue logic or interface preprocessing.
• Security-Sensitive Embedded Control – Nonvolatile configuration and FuseLock protection make the device suitable for embedded designs that require secure bitstream storage and protection.
• Boundary-Scan Test and In-System Verification – IEEE 1149.1 boundary-scan and Silicon Explorer II support simplify production test and in-system diagnostics.

Unique Advantages

• Compact, nonvolatile solution: Integrated nonvolatile configuration removes external configuration memory, simplifying BOM and board complexity.
• Flexible I/O for mixed systems: Wide voltage support and 5 V tolerance allow direct interfacing to common logic families without external translators.
• Deterministic timing control: Family features include user-controllable timing characteristics useful for predictable, repeatable system behavior.
• Security-oriented programming: FuseLock technology helps safeguard intellectual property and prevents reverse engineering of the implemented design.
• Production-friendly testability: IEEE 1149.1 boundary-scan and in-system diagnostic capabilities streamline manufacturing test and field verification.
• Commercial temperature and RoHS compliance: Rated for 0 °C to 70 °C operation and RoHS status is compliant to simplify regulatory considerations.
