Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements provide the programmable resources needed for medium-complexity FPGA functions.
• Flip-Flops / Register Resources — Dedicated flip-flop resources are provided as part of the SX-A family architecture to support synchronous logic (refer to family datasheet for device-specific flip-flop counts).
• I/O — 69 user I/O pins in the 84‑pin CQFP package, suitable for a range of external interfaces and signal routing in compact board designs.
• Performance (HiRel SX-A Family) — Family datasheet specifies up to 215 MHz system performance and 5.3 ns clock‑to‑out at military temperature for SX‑A devices, supporting deterministic timing requirements.
• Voltage Range & I/O Compatibility — Supports a wide supply range of 2.25 V to 5.25 V to accommodate mixed-voltage board environments.
• Package & Mounting — 84‑pin ceramic CQFP (42 × 42 mm) with exposed pad and tie bar; surface-mount mounting type for PCB assembly.
• Temperature & Grade — Military grade with operating temperature range of −55 °C to +125 °C and QML-class manufacturing flow referenced in the family documentation.
• Security & Reliability (Family-Level) — SX‑A family features Actel Secure Programming Technology with FuseLock™ and QML certification referenced in the family datasheet for protection against reverse engineering and design theft.
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• Defense & Aerospace Systems — Military-grade temperature range and QML-class family documentation make this FPGA suitable for avionics, tactical electronics and mission systems requiring ruggedized components.
• Secure Embedded Control — Family security features such as FuseLock™ support designs that require protection of IP and anti‑tamper measures.
• High-Reliability Control Electronics — Deterministic timing performance and ceramic CQFP packaging are a fit for high-reliability control and data-path logic in harsh environments.
• Mixed‑Voltage Interface Designs — Wide supply range and family I/O flexibility support interfacing to 2.5 V–5 V systems and legacy logic levels.

Unique Advantages

• Military-Grade Qualification: Delivered in a ceramic 84‑CQFP package with a specified −55 °C to +125 °C operating range and documented MIL‑STD‑883 product flow in the family datasheet.
• Compact, Mid‑Range Capacity: 48,000 system gates and 2,880 logic elements strike a balance between integration and board-space efficiency for moderate-complexity designs.
• Wide Supply Flexibility: Operates from 2.25 V to 5.25 V, enabling use in mixed-voltage systems without special power sequencing.
• Security-Focused Family Features: SX‑A family security mechanisms (FuseLock™) help protect design IP and prevent reverse engineering.
• Rugged Packaging: Ceramic CQFP with exposed pad and tie bar supports thermal performance and mechanical stability required by high-reliability assemblies.
