• System Reliability  Hot-swap compliant I/Os, power-up/power-down friendly operation (no sequencing required for supply voltages), and configurable weak pull-up or pull-down on I/Os at power-up.
• Design Determinism  Deterministic, user-controllable timing, individual output slew rate control, and support for up to 100% resource utilization with 100% pin locking.
• Package and Temperature  208-pin PQFP (28 × 28) surface-mount package; operating temperature range −55 °C to 125 °C suitable for military-grade applications.
• Supply Range and Compliance  Voltage supply range 2.25 V to 5.25 V; RoHS compliant.
• In-System Diagnostics  Unique in-system diagnostic and verification capability with Silicon Explorer II (as specified for the SX-A family).

Typical Applications

• Defense & Aerospace Systems  Military temperature rating (−55 °C to 125 °C) and robust I/O support make the device suitable for rugged, mission-critical embedded logic and interface tasks.
• High-Reliability Embedded Control  Deterministic timing, hot-swap I/Os, and power-up/down friendliness support reliable control, sequencing, and interface functions in embedded platforms.
• Communications & Interface Bridging  Configurable I/O standards and 66 MHz PCI compliance enable protocol bridging and custom interface logic in communication equipment and I/O subsystems.
• Secure, Field-Programmable Systems  Nonvolatile single-chip configuration and FuseLock™ secure programming protect intellectual property in programmable hardware deployed in the field.

Unique Advantages

• Highly integrated mid-range logic:  24,000 system gates and 1,452 logic elements provide substantial on-chip logic capacity without external PLD components.
• Flexible mixed-voltage I/O:  Supports multiple I/O standards and mixed-voltage operation, simplifying interface to legacy and modern logic domains.
• Rugged temperature performance:  Military-grade temperature range supports applications that require extended environmental tolerance.
• Nonvolatile configuration:  Single-chip nonvolatile solution removes the need for separate configuration memory and simplifies board-level design.
• Built-in security and test:  FuseLock™ secure programming and IEEE 1149.1 boundary-scan enable secure deployment and standard testability.
• System-friendly I/O and power behavior:  Hot-swap compliant I/Os and no required supply sequencing reduce system design constraints and improve uptime.
