2 K20 Family Introduction
The K20 MCU family is pin, peripheral and software compatible with the K10 MCU family and adds full and high-speed
USB 2.0 On-The-Go with device charger detect capability. Devices start from 32 KB of flash in 5 x 5 mm 32QFN packages
extending up to 1 MB in a 144MAPBGA package with a rich suite of analog, communication, security, timing and control
peripherals. High memory density K20 family devices include a single precision floating point unit and NAND flash
controller.
The K22 product family members are additional devices within the K20 family with lower power and higher memory
densities in smaller packages. The K21 family adds Tamper functionality to the K22 device. Within the K21 and K22
families, devices range from 128 KB of flash memory to 512 KB of flash memory. Package options include 48 LQFP up to
121 MAPBGA.
