NXP Semiconductors KE17Z / KE13Z / KE12Z

KE1xZ MCUs are based on Arm Cortex-M0+ core, running up to 72 MHz. Optional robust TSI module provides a high level of stability and accuracy to any HMI system. The 1-Msps ADC and FlexTimer modules provide an ideal solution for BLDC motor-control systems. The MSCAN IP (offered on selected part numbers) is ideal for the CAN node control and auto after car market applications.

Newly launched KE17Z / KE13Z / KE12Z integrates up to 256 KB Flash and 48 KB RAM, in which the KE17Z family represents NXP’s latest offering to bring dual TSI with up to 50 channels into the Kinetis E product portfolio.
