K22F Family Product Brief
Supports 120/100MHz devices with 128KB to 512KB
Embedded Flash
Contents
1 K22F Family Introduction
The K22F microcontrollers are based on the ARM
®
Cortex™-
M4 core and are the second generation of devices within the
Kinetis K2x family, offering lower power and higher memory
densities in smaller packages than before. The K22F devices
have 100 MHz and 120 MHz performance options with an
integrated single-precision floating-point unit. Embedded flash
memory sizes range from 128 KB to 1 MB. Packages include
64-pin up to 144-pin LQFP and BGA options.
This product brief describes the K22F devices from 128 KB to
512 KB package options, from 64-pin up to 121-pin. For
further information on other K2x family products, see
