Overview
The Kinetis MCU portfolio consists of multiple pin-, peripheral- and software-compatible MCU
families based on the ARM
®
Cortex™-M4 core. Families are built from innovative 90 nm thin-film
storage (TFS) flash technology with unique FlexMemory (EEPROM) capability, and offer industry-
leading low power and mixed signal analog integration.
The K40 MCU family adds Full-Speed USB 2.0 On-The-Go with device charger detect capability
and a flexible, low-power segment LCD controller with support for up to 320 segments. Devices
start from 64 KB of flash in 64 LQFN packages extending up to 512 KB in a 144 MAPBGA package
with a rich suite of analog, communication, timing and control peripherals.
