Key Features

• Logic Capacity — 48,000 system gates and approximately 2,880 logic elements, enabling moderate-complexity logic integration in a single device.
• I/O Resources — 174 user I/Os available in the 208-pin package; I/Os support hot-swap operation and configurable weak pull-up or pull-down at power-up.
• Performance (SX‑A family) — Family-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical designs.
• Voltage and Power — Wide supply range from 2.25 V to 5.25 V with support for mixed 2.5 V, 3.3 V and 5 V I/O operation and 5 V input tolerance and drive strength as provided by the SX‑A family.
• Nonvolatile Single‑Chip Configuration — SX‑A family single-chip, nonvolatile architecture removes the need for an external configuration memory device.
• Package and Mounting — 208‑BFQFP (supplier package: 208‑PQFP, 28×28) surface-mount package suitable for compact board-level integration.
• Temperature and Grade — Industrial grade with operating temperature range of −40 °C to +85 °C.
• Security and Diagnostics — Family features include Actel Secure Programming Technology (FuseLock™) to protect designs and in-system diagnostic/verification capability with Silicon Explorer II.
• Testing and Standards — Boundary-scan testing in compliance with IEEE 1149.1 (JTAG) and family-level support for 66 MHz PCI compliance.
• Design Control — Deterministic, user-controllable timing, individual output slew-rate control, and up to 100% resource utilization with 100% pin locking from the SX‑A family feature set.
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• Industrial Control — Implement motion control, custom logic, and real-time interfacing where industrial temperature range and robust I/O tolerance are required.
• Embedded Systems — Integrate glue-logic, peripheral interfaces, and application-specific processing in compact systems using the device’s nonvolatile configuration and mixed-voltage I/O.
• PCI and Legacy Interfaces — Use family-level 66 MHz PCI compliance and 5 V tolerant I/Os to bridge or interface with legacy PCI and TTL-level peripherals.
• In-System Test and Secure Designs — Leverage JTAG boundary-scan and FuseLock security to support manufacturing test, field diagnostics, and intellectual property protection.

Unique Advantages

• Single‑Chip Nonvolatile Architecture: Eliminates external configuration memory and simplifies system BOM and power-up sequencing.
• Wide Supply and I/O Flexibility: 2.25 V–5.25 V supply range and mixed‑voltage I/O support reduce board-level level‑shifting complexity.
• Industrial Temperature Rating: Specified −40 °C to +85 °C for deployment in industrial environments.
• Security and IP Protection: FuseLock™ technology provides hardware-level protection against reverse engineering of programmed designs.
• Manufacturing and Test Support: IEEE 1149.1 boundary-scan and in-system diagnostic capabilities streamline production test and field troubleshooting.
• Compact Package with Ample I/O: 208-pin BFQFP footprint delivers 174 user I/Os for dense I/O requirements in space-constrained boards.
