• Nonvolatile Single-Chip Architecture Nonvolatile, single-chip solution eliminates the need for external configuration memory and supports in-system programmability and verification.
• Power and Hot-Swap Friendly Power-up/power-down friendly operation (no sequencing required) and hot-swap compliant I/Os. Configurable weak pull-up/pull-down options at power-up and individual output slew-rate control.
• Security and Testability Actel Secure Programming Technology with FuseLock to protect design IP and support for IEEE 1149.1 boundary-scan (JTAG) testing. In-system diagnostic and verification capability with Silicon Explorer II.
• Package and Environmental 329-ball BGA (supplier package 329-PBGA, 31×31) surface-mount device, RoHS compliant, industrial grade with an operating temperature range of -40 °C to 85 °C.
• Supply Voltage Range Wide supply tolerance from 2.25 V to 5.25 V for flexible system integration.
• Embedded Memory Product specification lists no dedicated on-chip RAM bits (Total RAM Bits: 0), enabling deterministic logic resource planning based on logic elements and flip-flop resources.

Typical Applications

• PCI-based Systems — 66 MHz PCI compliance and configurable 3.3 V/5 V PCI I/O support make the device suitable for PCI add-in logic and bus-bridge functions.
• Mixed-Voltage Interface and Level Translation — Mixed-voltage I/O support and wide supply range enable bridging and interface logic between 2.5 V, 3.3 V and 5 V domains.
• Industrial Control and Embedded Logic — Industrial-grade temperature rating (-40 °C to 85 °C) and high I/O density support control, automation and embedded processing tasks requiring reliable field operation.
• Secure and Testable Programmable Logic — Built-in FuseLock security and IEEE 1149.1 boundary-scan support address requirements for IP protection and board-level testability.

Unique Advantages
