Key Features

• Core Capacity — 24,000 system gates and 1,452 logic elements provide a mid-range logic resource set suitable for control, glue logic and peripheral functions.
• I/O and Voltage Flexibility — 81 user I/Os with configurable drive characteristics. Supports mixed-voltage operation with a documented supply range of 2.25 V to 5.25 V to accommodate multiple I/O standards.
• Performance (SX-A family) — SX-A family performance figures include up to 250 MHz system performance and up to 350 MHz internal performance, supporting demanding logic timing when needed.
• Nonvolatile Single‑Chip Solution — On-chip nonvolatile configuration eliminates the need for external configuration memory and simplifies board-level BOM and boot sequencing.
• System and Test Features — Supports IEEE 1149.1 boundary-scan (JTAG) for board-level testing; includes in-system diagnostic and verification capability as provided in the SX-A family tools.
• Hot-Swap and Power-Friendly I/Os — I/O architecture supports hot-swap compliant operation and power-up/power-down friendly behavior without strict supply sequencing.
• Package & Temperature — Delivered in a 100‑pin LQFP package (supplier device package 100‑TQFP, 14×14). Commercial temperature grade with an operating range of 0 °C to 70 °C.
• Environmental Compliance — RoHS compliant.
• Security and Protection — SX-A family features Actel Secure Programming Technology (FuseLock™) to protect designs against reverse engineering and unauthorized readout.

Typical Applications

• PCI and legacy peripheral interfaces — Family-level support for 66 MHz PCI and configurable I/O levels enables implementation of PCI-compliant interface logic and glue components.
• Mixed‑voltage system glue logic — Configurable I/O for 5 V and 3.3 V signaling simplifies level translation and interface consolidation on mixed-voltage boards.
• In‑system diagnostics and test — Built-in boundary-scan (IEEE 1149.1) and in-system verification tools support board testability and fault isolation workflows.
• Hot-swap and power sequencing control — Hot-swap compliant I/Os and power-up/power-down friendly behavior make it suitable for systems requiring modular board insertion or live serviceability.

Unique Advantages

• Single‑chip nonvolatile configuration — Eliminates external configuration memory and simplifies board-level design and startup sequencing.
• Flexible mixed‑voltage I/O — Wide supply and I/O configurability reduce the need for external level shifters and lower BOM complexity.
• Deterministic, user‑controllable timing — SX-A family timing controls support predictable behavior for timing-sensitive designs.
• Testability and diagnostics — IEEE 1149.1 boundary-scan and in-system diagnostic features accelerate bring-up and production testing.
• Security features — FuseLock technology provides protection against reverse engineering and intellectual property theft.
• Commercial temperature and RoHS compliance — Suitable for standard commercial applications with documented operating range and environmental compliance.
