MKS22FN256VLH12    KS22/KS20 Microcontroller

120 MHz ARM® Cortex®-M4, with up to 256 KB Flash

ARM微控制器 - MCU Kinetis S 32-bit MCU, ARM Cortex-M4 core, 256KB Flash, 120MHz, CAN, USB, LQFP 64

The KS2x product family is built on the ARM® Cortex®-M4

processor with lower power and higher memory densities in

multiple packages. This device offers 120 MHz performance with

an integrated single-precision floating point unit (FPU).

Embedded flash memory sizes range from 128 KB to 256KB.

This device also includes:

• USB FS OTG 2.0 with crystal-less functionality

• FlexCAN, supporting CAN protocol according to the ISO

11898-1 standard and CAN 2.0 B protocol specifications

• FlexIO, a highly configurable module providing a wide

range of protocols including, but not limited to UART,

LPI2C, SPI, I2S, and PWM/Waveform generation.
