MCU scaled down to the size of a golf ball dimple
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
* -40°C to 85°C 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.
