Freescale’s Insanely Tiny ARM Chip Will Put the Internet of Things Inside Your Body.

Chipmaker Freescale Semiconductor has created the world’s smallest ARM-powered chip, designed to push the world of connected devices into surprising places.
Announced today, 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 body needs to be a basic tiny 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.
