ARM-powered MCU touted as world’s smallest
The KL02 targets ultra-small form factor products in applications such as portable consumer devices, remote sensing nodes, wearable devices and ingestible healthcare sensing, added the company.
Measuring 1.9 x 2mm, the Kinetis KL02 MCU is said to be 25 per cent smaller than the industry’s next-smallest ARM MCU.
Within this miniscule device, Freescale has included the latest 32bit ARM Cortex-M0+ processor, cutting-edge low-power functionality and a range of analogue and communication peripherals.
This enables system designers to dramatically cut the size of their boards and products while retaining the all-important performance, feature integration and power consumption characteristics of their end devices. In addition, space-constrained applications that previously couldn’t incorporate an MCU now can be upgraded to become smart applications, adding a new tier of devices to the IoT ecosystem.
Building upon the energy efficiency of the Cortex-M0+ core, the Kinetis KL02 MCU reduces the power consumption threshold of the Kinetis L series to an even lower entry point and is ideal for the demanding power profiles of miniaturized IoT-linked systems.
The KL02 delivers 15.9CM/mA and, like other Kinetis MCUs, it includes autonomous, power-smart peripherals (in this case, an ADC, UART and timer), 10 flexible power modes and wide clock and power gating to minimise power loss. A low-power boot mode reduces power spikes during the boot sequence or deep sleep wake-up.
This is useful for systems in which battery chemistry limits the allowable peak current such as those using lithium-ion batteries frequently used in portable devices.
The Kinetis KL02 MCU features a 48MHz ARM Cortex-M0+ core touting operation from 1.71-3.6V, bit manipulation engine for faster, more code-efficient handling of peripheral registers, 32KB flash memory, 4KB RAM and high-speed 12bit ADC.
In addition, the device boasts a high-speed analogue comparator, low-power UART, SPI, 2x IICI2C, powerful timers for a range of applications including motor control and -40°C to 85°C operation.
The Kinetis KL02 CSP MCU is expected to begin sampling to lead
customers in March 2013.
Broad market availability of production-qualified samples is planned for July 2013 from Freescale and its distribution partners. Suggested resale pricing is $ 0.75 cents in 100,000-unit quantities.
