• Security and Diagnostics — Family-level Actel Secure Programming Technology with FuseLock and in-system diagnostic/verification capability via Silicon Explorer II provide protection and visibility for deployed designs.
• Industrial Temperature Grade — Rated for operation from −40°C to 85°C, suitable for industrial environments.
• Package & Mounting — Surface-mount 100-LQFP package case; supplier package referenced as 100-TQFP (14×14).
• Supply Voltage — Flexible supply range from 2.25 V to 5.25 V to support a wide variety of system architectures.
• RoHS Compliant — Device is RoHS compliant for environmental and manufacturability considerations.

Typical Applications

• Industrial control and automation — Deterministic logic capacity and industrial temperature rating make this FPGA suited for board-level control, protocol handling and custom I/O in automation systems.
• PCI and legacy bus interfacing — Family-level 66 MHz PCI compliance and mixed-voltage I/O support enable bridging and interface logic for PCI-based designs and legacy bus integration.
• Embedded system glue logic — Use the device to consolidate glue logic, peripheral controllers and custom state machines, reducing BOM and PCB routing complexity.
• Secure programmable logic — Built-in secure programming and in-system verification features support IP protection and controlled field updates for critical applications.

Unique Advantages

• Nonvolatile, single-chip programmability: Eliminates external configuration memory and simplifies board design and power sequencing.
• Flexible mixed-voltage I/O: Direct support for 2.5 V, 3.3 V and 5 V signaling with 5 V tolerance enables simpler interfacing to a wide range of peripherals and legacy devices.
• Industrial temperature capability: Rated −40°C to 85°C for deployment in harsher environments where commercial-grade parts are not suitable.
• Built-in security and diagnostics: FuseLock secure programming and Silicon Explorer II in-system diagnostics provide IP protection and faster in-field validation.
• Deterministic timing and testability: Family features include deterministic, user-controllable timing and IEEE 1149.1 boundary-scan for predictable performance and easier manufacturing test.
• Compact, surface-mount package: 100-pin quad-flat package simplifies placement on compact PCBs while offering 81 user I/Os for practical system I/O needs.
