• I/O — 81 user I/O pins with configurable I/O options support mixed-voltage operation and flexible interfacing to external devices.
• Nonvolatile Single-Chip Solution — On-chip nonvolatile configuration removes the need for external configuration memory and enables secure, field-programmable operation.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as specified for the family.
• Power and Voltage Flexibility — Operates across a wide supply range (2.25 V to 5.25 V) and supports mixed-voltage operation including 2.5 V, 3.3 V and 5 V modes as defined for the SX-A family.
• Robust I/O and System Behavior — Hot-swap–compliant I/Os and power-up/power-down friendly behavior (no sequencing required) simplify integration into multi-rail systems.
• Security and Test — Includes Actel Secure Programming Technology (FuseLock™) to prevent reverse engineering and supports boundary-scan testing (IEEE 1149.1/JTAG) plus in-system diagnostic capabilities.
• Package and Grade — Available in a 100-pin LQFP package (product lists 100-LQFP) and specified as Military grade with an operating temperature range of −55 °C to 125 °C; supplier device package listed as 100-TQFP (14×14).
• Standards and Interfaces — SX-A family devices include PCI-compliant I/O options (66 MHz) and configurable I/O support for multiple signaling standards as defined for the family.
• Compliance — RoHS compliant.

Typical Applications

• Defense and Aerospace Systems — Military-grade temperature rating and high-reliability single-chip nonvolatile configuration make this FPGA suitable for mission-critical embedded subsystems.
• Secure Embedded Designs — FuseLock™ security and in-system verification support designs requiring protection against reverse engineering and enhanced device integrity.
• Protocol Bridging and I/O Management — Flexible, mixed-voltage I/O and abundant logic resources are well suited for interfacing, protocol conversion and peripheral control in complex systems.
