NXP's KE1xZ64/32 product family is based on the Arm® Cortex®-M0+ core running at 48 MHz, offering smaller memory options of 64 KB/8 KB or 32 KB/4 KB Flash/SRAM. It expands the KE1xZ series down to 64 KB and 32 KB Flash options, 8 KB and 4 KB SRAM options, leading to optimized BOM cost along with TSI and CAN interfaces. The KE14Z is a broad offering with mixed-signal integration, ADC, ACMP, timers, PDB, and ranging from 32 KB Flash to 256 KB Flash. The KE15Z expands from the KE14Z family with an addition of a TSI module, and ranging from 32 KB Flash to 256 KB Flash. The KE16Z further expands the line with the addition of a CAN module to the KE15Z family.
The FRDM-KE16Z freedom board development board is designed to work in standalone mode or as the main board of FRDM-TOUCH. This freedom board is compatible with DC 5 V and 3.3 V power supplies and features a KE16Z. The onboard interfaces include an RGB LED, a 6-axis digital sensor, a 3-axis digital angular rate gyroscope, an ambient light sensor, CAN control interface, and capacitive touchpad.
The FRDM-TOUCH is a touch module for FRDM-KE15Z and FRDM-KE16Z with capacitive touch sliders. This board can connect FRDM-KE15Z and FRDM-KE16Z and control the on-board RBG LED by using keys, slider, and rotary touches.
