Freescale Semiconductor has rolled out what it says is the world's smallest 32bit ARM-based microcontroller. The Kinetis KL03 MCU is available in a 1.6 x 2mm package, representing a 15 percent smaller package than the earlier Kinetis KL02 MCU, stated the company.

The MCU augments with earlier processor with features including low power UART, additional low-power wake-up pins and an on-chip voltage reference designed to provide improved accuracy for the on-chip ADC. The KL03 ADC can also operate in ratiometric mode without the use of the voltage reference for power sensitive applications.

The MCU features a 48MHz ARM Cortex-M0+ core operating from 1.71-3.6V, and a bit manipulation engine for faster, more code-efficient handling of peripheral registers. It also boasts a 32KB flash memory, 2KB RAM, 8K ROM with on-chip boot loader and a high-speed 12bit ADC.

Additionally, the Kinetis KL03 MCU offers internal voltage reference for high ADC accuracy, high-speed analog comparator, low power wake up, low-power UART, SPI, I2C (high speed), secure real time clock and timers for a broad range of applications including motor control. The device operates from -40°C to 85°C.

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 in 100K-unit quantities.
