Keywords:MCU? Freescale? chip? Kinetis?

Freeescale Semiconductor has engineered a 1.6x2.0mm2 MCU package, earning the world's smallest 32bit ARM-based MCU bill. The Kinetis KL03 is 15 per cent smaller than the previous KL02.

A smaller and enhanced version of its predecessor, the KL03 features low power UART, additional low-power wake-up pins and an on-chip voltage reference for improved accuracy of the ADC. Without the use of a voltage reference, the chip can function in ratiometric mode for power sensitive applications.

Key features in the KL03 include:

* 48MHz ARM Cortex M0+ core, 1.71V to 3.6V operation

* Bit manipulation engine for faster, more code-efficient handling of peripheral registers

* 32KB flash memory, 2KB RAM

* 8K ROM with on-chip boot loader

* High-speed 12bit analogue-to-digital converter

* Internal voltage reference for high ADC accuracy

* High-speed analogue comparator

* Low power wake up

* Low-power UART, SPI, I2C (high speed)

* Secure real time clock

* Timers for a broad range of applications including motor control

* -40C to 85C operation

Development support includes the Freescale Freedom development platform, Processor Expert development system, and Solution Advisor guide as well as Freescale and third-party support in the ARM ecosystem.

Initial sampling of the Kinetis KL03 MCU begins in March 2014 with full production planned for June 2014. Suggested resale pricing is $0.75 (USD) in 100K-unit quantities.
