SX-A family characteristics include high internal and system performance and on-chip features for system-level integration and testability.

Key Features

• Core and Performance — 48,000 system gates and 2,880 logic elements provide programmable logic density suitable for complex glue logic, protocol handling, and custom datapath implementations. The SX-A family cites up to 250 MHz system performance and up to 350 MHz internal performance.
• User I/O and Mixed-Voltage Support — 113 user-programmable I/Os on the 144-TQFP package; configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 is provided at the family level.
• Nonvolatile Single-Chip Solution — On-device nonvolatile configuration eliminates the need for external configuration memory, simplifying board design and system bring-up.
• Power and I/O Robustness — Hot-swap compliant I/Os, power-up/power-down friendly operation (no sequencing required), and 5 V input tolerance with 5 V drive strength (family-level characteristics) support mixed-voltage system integration.
• Security and Test — Includes Actel Secure Programming Technology with FuseLock™ (family feature) and IEEE 1149.1-compliant boundary-scan for in-system testing and protection against reverse engineering.
• System Diagnostics — Unique in-system diagnostic and verification capability via Silicon Explorer II (family-level tool support) for debug and field verification.
• Package, Mounting and Environmental — 144-LQFP (thin TQFP) surface-mount package; military grade with operating temperature from -55 °C to 125 °C and RoHS-compliant status.
• Voltage Supply — Operates across a wide supply range of 2.25 V to 5.25 V to accommodate multiple system power rails.

Typical Applications

• Military and Aerospace Electronics — Military-grade temperature rating (-55 °C to 125 °C) and a rugged surface-mount 144-LQFP package make the device suitable for avionics, tactical systems, and other high-reliability embedded designs.
• Mixed-Voltage Interface Bridging — Configurable I/Os and 5 V tolerance enable interfacing between legacy 5 V systems and modern lower-voltage logic for protocol bridging or I/O expansion.
• Secure Embedded Control — Nonvolatile configuration and FuseLock™ security (family feature) are useful where on-board code retention and protection from reverse engineering are required.
• In-System Test and Diagnostics — Boundary-scan support and Silicon Explorer II diagnostics aid manufacturing test, field verification, and in-circuit debug of deployed systems.

Unique Advantages

• Nonvolatile, Single-Chip Configuration: Eliminates external configuration memory and simplifies BOM and board layout.
• Wide Supply and I/O Flexibility: 2.25 V–5.25 V supply range and family-level mixed-voltage I/O support ease integration into diverse system power domains.
