• Performance — SX-A family specifications list up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical functions.
• System & Security — Nonvolatile, single-chip architecture with Actel Secure Programming Technology and FuseLock™ to help protect design intellectual property; JTAG boundary-scan (IEEE 1149.1) for test.
• Programmability & Control — Deterministic, user-controllable timing, configurable weak pull-up/pull-down on I/Os at power-up, and individual output slew-rate control for signal integrity and timing management.
• Diagnostics & Test — In-system diagnostic and verification support via Silicon Explorer II and boundary-scan testing for board-level validation.
• Package & Mounting — Available in 100-pin thin quad flat package (listed as 100-LQFP / 100-TQFP 14×14); surface-mount mounting type for compact board designs.
• Temperature & Compliance — Industrial temperature grade rated from −40 °C to 85 °C and RoHS-compliant packaging.

Typical Applications

• PCI-based expansion and interface cards — Family-level 66 MHz PCI compliance and configurable 3.3 V/5 V PCI I/O support make this device suitable for board-level PCI interfaces.
• Mixed-voltage I/O bridging — Use the device where multiple logic-voltage domains must be interfaced, leveraging 2.5 V, 3.3 V and 5 V mixed-voltage operation and 5 V input tolerance.
• Industrial control and automation — Industrial temperature rating (−40 °C to 85 °C) and robust I/O configurability support factory and process-control electronics.
• Secure embedded systems — Built-in secure programming and FuseLock™ protection help protect IP in applications that require design security.
• Board-level signal-management — Deterministic timing controls, output slew-rate adjustment and configurable pull-ups/pull-downs assist in glue-logic, protocol bridging and timing-critical glue functions.

Unique Advantages

• Balanced mid-range capacity: 24,000 system gates with ~1,452 logic elements deliver practical programmability for a wide set of interface and control tasks without excessive board-level complexity.
• Flexible I/O and voltage handling: Mixed-voltage operation and 5 V tolerance support multiple domain interfaces and reduce the need for external level-shifters.
• Nonvolatile single-chip solution: Built-in nonvolatile configuration simplifies system power sequencing and reduces external configuration components.
