The Kinetis KL02 measures just 1.9 by 2 millimeters. It’s a full microcontroller unit (MCU), meaning the chip sports a processor, RAM, ROM, clock and I/O control unit — everything a chip needs to be a 'computer'.
The KL02 has 32k of flash memory, 4k of RAM, a 32 bit processor, and peripherals like a 12-bit analog to digital converter and a low-power UART built into the chip. By including these extra parts, device makers can shrink down their designs, resulting in tiny boards in tiny devices.
The KL02 is part of Freescale’s push to make chips tailored to the Internet of Things. The KL02 is intended to be at the heart of a network of connected objects, moving from shoes that wirelessly report your steps to pipes that warn you when they are leaking.
One application that Freescale says the chips could be used for is 'swallowable computers'. Both the Fitbit and OmniPod insulin pump use Freescale chips. It’s not hard to imagine a new generation of devices designed to monitor your internal health or release drugs and medicine from within your body.
