5 V MCU Family Provides Water Tolerant Touch Integration

NXP Semiconductor has announced its 5 V KE1xZ family of MCUs. Based on the Arm Cortex-M0+ core, the MCUs are suited for embedded control systems in harsh electrical environments and provide an integrated CAN controller and capacitive touch from 32 KB flash. Designed for a wide range of industrial applications, the KE1xZ family offers mixed-signal integration across a range of compact memory variants. The 1-MS/s ADC and FlexTimer modules, combined with NXP’s Freemaster software tools library and Motor Control Application Tuning plugin (MCAT) enable designs of Brushless DC (BLDC) and other motor-control systems.

NXP’s KE1xZ MCU family offers advanced noise immunity, water-tolerant touch and low-power wake-on-touch operation—essential features for the strict electromagnetic compatibility (EMC) standards of the industrial and home appliance markets. NXP’s touch IP, combined with software and tools provide a high level of stability, accuracy and ease of use, with continued responsiveness and functionality through wet conditions. It can sustain 10 V in conducted noise, in alignment with International Electrotechnical Commission (IEC) 6100-4-6 test level 3.

Additional KE1xZ MCU features:

  • Internal 48MHz internal reference clock with 1% accuracy over full operating range
  • Boot ROM with built in bootloader and 128-bit unique device identifier (UID)
  • ADC self-calibration feature
  • Flash Access Control (FAC)
  • Cyclic Redundancy Check (CRC) generator module
  • Internal watchdog (WDOG) with independent clock source and external watchdog monitor (EWM)
  • On-chip clock loss monitoring
  • IEC 60730 Class B safety certification
  • LQFP package with 48- and 44-pin options

The KE1xZ MCU family will be available globally in March 2019 from NXP and its distribution partners with a suggested resale price from $0.79 at 10,000-unit quantities. NXP enables developers through its MCUXpresso software and tools ecosystem, along with its FRDM-KE15Z and FRDM-TOUCH development platforms (see image above), with respective suggested resale prices of $35 and $15. Third-party support is enabled from the broad ARM ecosystem.
