Freescale Unveils Kinetis KL02, an Ultra Small (1.9×2.0mm) ARM Cortex M0+ Microcontroller

Freescale Semiconductor introduced the Kinetis KL02, the world’s smallest ARM MCU, at Embedded World 2013. KL02 is an ARM Cortex M0+ micro-controller designed to address the miniaturization needs of the Internet of things, and its size (1.9×2.0mm) makes it suitable for applications such as ingestible healthcare sensing, portable consumer devices, remote sensing nodes, and wearable devices.


Kinetis KL02 MCU features include:

  • 48 MHz ARM Cortex-M0+ core, 1.71-3.6V operation
  • Bit manipulation engine for faster, more code-efficient handling of peripheral registers
  • 32 KB flash memory, 4 KB RAM
  • High-speed 12-bit analog-to-digital converter
  • High-speed analog comparator
  • Low-power UART, SPI, 2x IICI2C
  • Powerful timers for a broad range of applications including motor control
  • Power Efficiency – 15.9 CM/mA (Coremark 1.0)
  • -40 °C to +85 °C operation

The MCU is manufactured using chip-scale package (CSP) technology that allows to connect the die directly to the solder ball interconnects and, in turn, to the printed circuit board (PCB). Freescale explains “this removes the need for bond wires or interposer connections, which minimizes die-to-PCB inductance and improves thermal conduction and package durability for physically harsh environments.”

Freescale Freedom development platform (FRDM-KL02) and related tools should be available in July 2013, but in the meantime, Freescale suggests customers to start development with FRDM-KL05Z Freescale Freedom development platform which will be available in March/April.

Kinetis KL02 CSP MCU should start sampling to key customers in March 2013, which broad market availability planned for July 2013. Unit price should be around $0.75 cents in 100,000-unit quantities.
