The KW20 chipsets bring together performance and security in a scalable ZigBee platform, allowing designers to optimize solutions to fit their specific applications.
As the Internet of Things becomes a reality and more devices require wireless connectivity, processing and memory requirements continue to climb, and scalability becomes more important. With the Kinetis KW20 wireless MCU solution, designers can quickly make feature changes without going back to the drawing board. The KW20 wireless MCU provides greater processing power and larger flash and RAM options compared to other devices on the market, helping end applications avoid obsolescence as specifications evolve.
The Kinetis KW20 wireless MCU family is designed to address the increased processing and memory requirements associated with future ZigBee Smart Energy 2.0 and Internet Protocol specifications. The MCU integrates an ARM Cortex-M4 processor, MC13242 RF transceiver and a robust feature set to provide a reliable, secure, low-power ZigBee platform. Designers can select the KW20 MCU single-chip solution or choose to combine the RF transceiver with a corresponding Kinetis MCU, giving them more flexibility to tailor the device to their specific application needs.
“The Kinetis KW20 wireless MCU provides the performance to handle smart energy applications’ memory and security needs, while giving designers the ultimate in flexibility,” said Bruno Baylac, director of Freescale’s Metering, Medical & Connectivity Solutions business. “By integrating ZigBee connectivity with our award-winning Kinetis MCU family, we are helping customers future-proof their systems while gaining a higher-performance radio and extra security.”
Freescale’s KW20 wireless MCU and MC13242 RF transceiver provide leading RF performance by reducing power consumption and increasing link budget. The transceiver features antenna diversity, which improves RF reliability, especially for conditions where multipath interference occurs. The KW20 wireless MCU and MC13242 transceiver are designed to reduce transmit and receive power, and a low-power run mode optimizes energy use.
The KW20 wireless MCU and MC13242 also offer dual personal area network (PAN) support, enabling a single device to
