• Voltage and power — Wide voltage supply range from 2.25 V to 5.25 V enabling 2.5 V, 3.3 V and 5 V mixed-voltage designs with 5 V input tolerance and 5 V drive strength supported by the family.
• Nonvolatile single-chip configuration — Single-chip, nonvolatile architecture removes the need for external configuration memory and supports power-up/power-down friendly operation.
• System interfaces and compliance — Family-level features include 66 MHz PCI compliance and configurable I/O for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling.
• Reliability and security — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering.
• Diagnostics and verification — Family supports in-system diagnostic and verification capabilities (Silicon Explorer II) for design validation and troubleshooting.
• Package and mounting — Surface-mount 256-ball fine-pitch BGA (256-FPBGA, 17×17) suitable for compact board designs; RoHS compliant.
• Commercial temperature grade — Rated for operation from 0 °C to 70 °C.
• On-chip memory — Total RAM bits: 0 (no embedded RAM).

Typical Applications

• PCI interface logic — Implements 66 MHz PCI-compliant peripheral or bridge functions using configurable I/O and deterministic timing.
• Mixed-voltage system glue — Bridges between 2.5 V, 3.3 V and 5 V domains with 5 V tolerant inputs and selectable I/O standards.
• Custom protocol and control logic — Deploys complex state machines and timing-critical logic using 108,000 system gates and ~6,036 logic elements.

Unique Advantages

• Nonvolatile, single-chip configuration: Eliminates external configuration storage and simplifies power-up behavior for reliable system bring-up.
• High logic density: 108,000 system gates and ~6,036 logic elements provide the capacity to integrate multiple functions on a single device, reducing BOM count.
• Flexible mixed-voltage I/O: Configurable I/O standards and 5 V tolerance make it straightforward to interface with legacy and modern logic families.
• Security and testability: FuseLock™ secure programming and IEEE 1149.1 boundary-scan support help protect IP and ease manufacturing test.
• Compact, high-pin-count package: 256-FPBGA (17×17) package with 203 I/Os provides density for complex board-level interconnect in a space-efficient footprint.
• Commercial-grade availability: Designed and specified for 0 °C to 70 °C operation with RoHS compliance for standard commercial applications.
