Freescale Kinetis K10 and K20 Ultra-Low-Power Microcontrollers Now Available for Cost-Sensitive Applications

AUSTIN, Texas – Feb. 16, 2012– Freescale Semiconductor (NYSE: FSL) announces sample availability of the low-power Kinetis K10 and K20 MCU derivatives, the lowest power Kinetis microcontrollers to date, consuming only 190 nA in VLLS0 stop mode and 270uA/MHz run mode with a maximum frequency of 50 MHz.  These devices complement the currently available 100MHz, 120MHz and 150MHz derivative options within the Kinetis K series of MCUs. They combine extensive feature integration with a small form factor, making them ideal for space- and cost-constrained applications, while expanding the Kinetis 32-bit MCU portfolio built on the ARM® Cortex™-M4 processor. The Kinetis K10 and K20 devices are suited for a broad range of applications, including I/O modules for factory automation, portable healthcare instruments, USB microphones and gaming headsets, as well as smart grid applications that demand solid processing power with aggressive low-power profiles.

Kinetis K10 and K20 microcontrollers are part of the Freescale Energy Efficient Solutions program, which highlights selected products that excel in effective implementation of energy-efficient technologies and/or deliver market-leading performance in the application spaces they are designed to address. The mark stands for Freescale’s technology expertise in delivering products optimized for high performance within the constrained energy and power budgets of embedded environments.


Tools and software

The K10 and K20 families are fully supported by a broad selection of easy-to-use 32-bit tools, including a package of Freescale´s MQX RTOS and software solutions, CodeWarrior for MCUs featuring Processor Expert Software, and a complimentary USB stack, as well as a range of third-party support. The Kinetis K20 MCU module evaluation and demonstration kit (TWR-K20D50M) based on the Freescale Tower System – a modular development platform designed to reduce development costs and time-to-market – is available now.

Availability and pricing

50 MHz Kinetis K10 and K20 64 LQFP and 32 QFN samples are available now through Freescale and its distribution partners. Mass production is expected to start in April 2012, with pricing starting at 99 cents (USD) suggested resale in 10,000-unit quantities. Additional package options (48 QFN, 48 LQFP and 64 MAPBGA) are planned for late Q1 and Q2 2012.
