• Package & Temperature 196-LFBGA package (12 × 12 mm, 0.8 mm pitch) rated for industrial junction temperatures from −40°C to +125°C.
• Compliance RoHS compliant.

Typical Applications

• Industrial Automation — Real-time control and communication in EtherCAT-based slave devices and distributed I/O modules using the dual EtherCAT ports and deterministic Cortex-R4 core.
• Motion and Motor Control — High-performance FPU and deterministic processing for motor control algorithms and closed-loop control tasks.
• Industrial Networking and Gateways — USB 2.0, CAN and multiple serial interfaces enable protocol bridging and edge-node connectivity in factory networks.
• Embedded Control Systems — Systems requiring robust watchdog, ECC-protected memory, and extended-temperature operation for harsh industrial environments.

Unique Advantages

• Real-time compute with FPU: Cortex-R4 core paired with a single-/double-precision FPU delivers deterministic math performance for control and signal processing.
• Integrated industrial connectivity: Built-in EtherCAT, USB 2.0 and CAN reduce external interface components and simplify system design.
