Freescale expands MCU portfolio with availability of Kinetis KW2x Wireless MCUs

AUSTIN, Texas – Dec. 5, 2013 – Freescale Semiconductor (NYSE: FSL) has expanded its Kinetis microcontroller (MCU) portfolio by initiating availability for its best-in-class 802.15.4/ZigBee® wireless solutions. Shipping now, the solutions are ideal for a broad range of applications including smart energy, home/building automation and home entertainment.

Freescale designed the Kinetis KW2x wireless MCU family to address the increased processing and memory requirements associated with future ZigBee Smart Energy 2.0 and Internet Protocol specifications. This new generation of world-class Kinetis wireless solutions further strengthens Freescale’s connectivity capabilities by adding to its already broad Internet of Things (IoT) portfolio.

The Kinetis KW2x wireless platform integrates an ARM® Cortex®-M4 processor, and a 802.15.4 Standard-compliant RF transceiver, incorporating a robust feature set to provide a reliable, secure, low-power 2.4 GHz platform.

The evolution of wireless connectivity
As the Internet of Things is quickly becoming reality, more devices are embedding wireless connectivity in addition to offering greater processing power and increased memory capacities to meet market demands. The KW2x wireless platform provides greater processing performance and larger flash and RAM options compared to other devices on the market, helping end-applications avoid obsolescence as specifications evolve. With the Kinetis KW2x wireless platform’s 512KB Flash and 64KB RAM, designers can quickly upgrade features without going back to the drawing board. For customers requiring more flexibility, the KW2x platform optionally provides 64K of FlexMemory that can be used for additional configurations.

Freescale’s KW2x wireless platform provides leading RF performance by reducing power consumption and increasing the link budget. The transceiver features antenna diversity, which improves RF reliability, especially for conditions where multipath interference occurs. The 802.15.4 transceiver is designed to reduce transmit and receive power, and a low-power run mode optimizes energy use.

The KW2x wireless MCU is distinguished by hardware assisted, dual personal area network (PAN) support, enabling a single device to communicate wirelessly on two ZigBee networks. This helps eliminate the need for multiple radios that in the past were necessary to connect different home automation and smart energy networks.

In addition, Freescale has integrated advanced security features usually found in higher-end processors to address the need for more advanced encryption methods including key generation, secure memory and tamper detect functionality. Secure flash protects the code and data from unauthorized access or modification, while tamper detect can identify events and asynchronously erase secure RAM, generating an interrupt so the application firmware can take additional actions, including a system reset. A cryptographic acceleration unit supports a set of specialized operations to improve the throughput of encryption/decryption operations as well as message digest functions.
