The lowest power mode consumes 40 nA and, together with a wide variety of low-power settings, users can achieve extension in battery life. The entry-level, 32-bit MCUs combine extensive feature integration with a small form factor, making them ideal for space- and cost-constrained applications.

The new ARM Cortex-M4 core K10 and K20 family members offer from 32 KB to 128 KB of flash memory in 32-pin QFN (5 mm x 5 mm) to 64-pin LQFP packages. Devices are built using Freescale’s innovative 90 nm thin film storage (TFS) low-leakage flash technology with up to 32 KB of optional FlexMemory (2 KB EEPROM), low power run and stop mode currents and fast wake-up times. Peripheral options include a 16-bit ADC, full-speed USB On-The-Go controller with complimentary software stack, low-power touch sensing interface and several general timing, communication and control peripherals.

The devices are targeted at 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.

The K10 and K20 families will be fully supported by a wide 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. Kinetis support from the ARM ecosystem will continue to thrive with support for the K10 and K20 families coming from IAR Systems, Keil, Green Hills Software, Atollic, open source GNU tools and several more. An evaluation and demonstration kit based on the Freescale Tower System – a modular development platform designed to reduce development costs and time-to-market – is planned for the first quarter of 2012.

Availability and Pricing

Freescale expects to begin providing alpha samples of the 50 MHz devices to select customers in Q4 2011 and devices are expected to be broadly available in early Q1 of 2012. Pricing starts from 99 cents for 10,000-unit quantities.
