• Configuration & Security Nonvolatile, single‑chip configuration with Actel Secure Programming Technology (FuseLock) to protect design IP.
• Test and Diagnostics IEEE 1149.1 (JTAG) boundary-scan support and in-system diagnostic/verification capability for board-level validation.
• Package & Temperature 329-ball PBGA (31 × 31 mm) package; industrial temperature grade rated from −40 °C to +85 °C.
• Standards & Compatibility 66 MHz PCI-compliant I/O option and configurable weak pull-up/pull-down on I/O at power-up.
• Regulatory RoHS-compliant packaging.

Typical Applications

• PCI-based systems — Implements programmable interfaces and glue logic for 66 MHz PCI or mixed-voltage I/O subsystems.
• Industrial control and automation — Provides deterministic timing and wide I/O count for sensor aggregation, motor control interfaces, and field I/O expansion within industrial temperature ranges.
• In-system test and verification — Integrates boundary-scan (IEEE 1149.1) and in-system diagnostics to simplify board bring-up and fault isolation.
• Mixed-voltage embedded designs — Supports 2.5 V, 3.3 V and 5 V signaling options to interface with a broad range of legacy and modern peripherals.

Unique Advantages
