MKE14Z256VLL7

The Kinetis KE1xZ256 MCU is the main device in the KE1xZ series based on the ARM Cortex M0+ core. The KE1xZ offers up to 256 KB of Flash, up to 32 KB of RAM, and a comprehensive set of analog/digital functions, elevating the Kinetis E series to higher performance and broader scalability. The robust TSI provides a high level of stability and accuracy for customers' HMI systems. The 1 Msps ADC and FlexTimer help build excellent solutions for BLDC motor control systems.
