Freescale Expands 32-bit Kinetic MCUs

Published:2011/9/19 3:13:00 Author:Amy From:SeekIC

Freescale, a leading manufacturer of enclosures for OEM electronics equipment, recently has developed its 32-bit Kinetis MCUs based on the ARM Cortex-M4 processor.

These ARM Cortex-M4 core K10 and K20 will be priced less than $1 each, making them well suited for cost-sensitive industrial and consumer appliances, including I/O modules for factory automation, portable healthcare instruments, USB microphones, gaming headsets, and smart grid applications.

The new devices are the lowest power Kinetis MCUs, consuming 630 uA at a CPU speed of 4 MHz in low power run mode, which is equal to 160uA/MHz. The lowest power mode consumes only 40 nA.

The devices provide from 32 KB to 128 KB of flash memory in 32-pin QFN (5-mm x 5-mm) to 64-pin LQFP packages. They are built using Freescale’s 90-nm thin film storage (TFS) low-leakage flash technology with up to 32 KB of optional FlexMemory (2 KB EEPROM), very 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 K10 and K20 will be supported by a wide selection of easy-to-use 32-bit tools, such as 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.

Alpha samples of the 50 MHz devices are expected to be available in Q4 and broadly available in early Q1 2012. Pricing starts from 99 cents (USD MSRP) for 10,000-unit quantities.
