Freescale is emphasising its capabilities in providing secure connectivity at all levels. Its Kinetis KV5x MCU family, Freescale asserts, uses the full performance potential of the ARM Cortex-M7 core in the rapidly evolving digital motor control market.

The migration toward digital-based control systems with secure networking capabilities presents a significant opportunity for both energy conservation and end-product feature innovation, which Freescale aims to address with its Kinetis KV5x MCU. The device combines processing power, sophisticated analogue and timing peripherals, and added connectivity, security and safety features, detailed the company. It claims to deliver increased motor efficiency, remote system management and end-node interoperability, via the Internet of Things (IoT), to applications from home appliances to complex industrial drives, added Freescale.

The Kinetis KV5x MCU incorporates an IEEE 1588 Ethernet controller, a cryptographic acceleration unit with random number generator, and a memory protection unit. With motors often employed in safety-critical environments such as manufacturing process control, these features allow developers to implement additional services via the IoT infrastructure while protecting against erroneous inputs that could lead to an undesired operating condition.
