• Nonvolatile Single-Chip Configuration  Nonvolatile, single-chip architecture eliminates the need for external configuration memory and supports in-system programmability and diagnostics.
• Power and I/O Robustness  Hot-swap compliant I/Os and power-up/power-down friendly operation with no sequencing required for supply voltages are included at the family level.
• Security and Test  Family features include Actel Secure Programming Technology (FuseLock™) to protect designs and IEEE 1149.1 (JTAG) boundary-scan testing for board-level diagnostics.
• Package and Mounting  Surface-mount 208-pin BFQFP (supplier package 208-PQFP, 28×28) for compact board integration.
• Electrical and Environmental  Supply voltage range 2.25 V to 5.25 V; RoHS compliant; military grade with operating temperature range of −55 °C to +125 °C.
• On-Chip Memory  Total on-chip RAM bits: 0 (no embedded RAM).

Typical Applications

• Military and Aerospace Systems  Military-grade temperature range (−55 °C to +125 °C) and surface-mount 208-pin packaging make the device suitable for high-reliability defense and aerospace electronics.
• PCI and Embedded I/O Interfaces  Configurable I/O support and family-level 66 MHz PCI compliance enable use in embedded PCI-connected modules and I/O bridging.
• Secure Embedded Control  Nonvolatile configuration combined with FuseLock™ security and JTAG boundary-scan supports secure, verifiable field-deployable systems.
• High-Reliability Industrial Electronics  Deterministic timing, hot-swap-compliant I/Os, and wide supply voltage tolerance suit rugged industrial control and instrumentation designs.

Unique Advantages

• Military-Grade Operation: Guaranteed operation from −55 °C to +125 °C for applications requiring extreme-temperature reliability.
