• Nonvolatile Single-Chip Solution — Built-in nonvolatile configuration enables single-chip FPGA solutions without external configuration memory (family-level feature).
• Mixed-Voltage I/O Support — Configurable I/O options support 5 V and 3.3 V PCI signaling, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 (family-level feature); 5 V input tolerance with selectable drive strengths.
• Power and Hot-Swap Friendly — Power-up/power-down friendly behavior with no required supply sequencing and I/Os designed for hot-swap compatibility (family-level features).
• Security and Test — Family-level features include boundary-scan (IEEE 1149.1 JTAG) for board test and Actel Secure Programming Technology with FuseLock™ for design protection.
• Package and Mounting — 144-LQFP package, surface-mount mounting type; supplier package reference 144-TQFP (20×20).
• Electrical and Environmental — Voltage supply range 2.25 V to 5.25 V; operating temperature −40 °C to 85 °C; RoHS compliant.
• Flip-Flops and Logic Resources — Device-level resources support a significant number of flip-flops and combinatorial logic consistent with the SX-A family architecture (family-level resource details available in datasheet).

Typical Applications

• Industrial Control — Implement control logic, interface glue, and custom state machines that require industrial-temperature operation and flexible I/O voltage support.
• System Interfaces and Legacy Bridging — Support mixed-voltage interface requirements and PCI signaling compatibility for bridging and interface adaptation tasks (family-level PCI compliance).
• Board-Level Programmable Logic — Replace fixed-function glue logic with reconfigurable logic to consolidate discrete parts and simplify BOM.
• Manufacturing Test and Diagnostics — Use integrated boundary-scan (IEEE 1149.1) for board-level test and in-system diagnostic workflows.

Unique Advantages

• Flexible I/O Voltage Support: Configurable I/O standards and 5 V input tolerance allow direct interfacing with a variety of legacy and modern logic levels, reducing level-shifter requirements.
• Nonvolatile, Single-Chip Configuration: Eliminates the need for external configuration memory, simplifying board design and reducing component count.
• Hot-Swap and Power-Friendly I/Os: I/Os designed for hot-swap compatibility and tolerant power-up/down behavior minimize sequencing constraints and increase system robustness.
• Industrial-Grade Operation: Specified for −40 °C to 85 °C operation, making the device suitable for industrial environments that require extended temperature range.
• Design Security and Testability: Boundary-scan support and FuseLock programming technology help protect intellectual property while supporting in-system test and verification.
• Proven Family Performance: SX-A family performance figures (up to 250 MHz system, up to 350 MHz internal) provide known baseline characteristics for system designers (family-level data).
