Kinetis KW36/35/34 Wireless MCU Family Block Diagram



  • Cortex-M0+ running up to 48 MHz
  • KW35: 512kB (2x256kB, swappable) Program Flash with ECC
  • KW36/34: 256kB Program Flash + 256kB FlexNVM both with ECC
  • 64k SRAM
  • KW36/34: 8 KB of user-segment defined byte write/erase EEPROM
    • Allocation of FlexNVM (minimum 32KB) to EEPROM emulation will determine effective endurance

  • Support for Bluetooth Low Energy version 5 and Generic FSK
  • Rx Sensitivity, -95 dBm Bluetooth Low Energy, -99 dBm Generic FSK
  • -25 to +5 dBm programmable output power
  • Increased coexistence performance; Radio I/O for Wi-Fi coexistence
  • 6.3 mA Rx and 5.7 mA Tx (0dBm) current target (DC-DC enabled)
  • Integrated balun (~9% board area savings)
  • Support for up to 8 simultaneous Bluetooth LE connections


  • 2xSPI, LP-UART with LIN, 2xI2C, CMT, GPIO with IRQ capability (KBI)
  • KW36: CAN FD and 2nd UART with LIN
  • 3x FlexTimer (TPM) with PWM and quadrature decode support
  • Low Power (LPTMR), Programmable Interrupt (PIT) and RTC timers


  • 16-bit ADC with an integrated temperature sensor and battery monitor
  • 6-bit High-speed Analog Comparator


  • AES Accelerator and True Random Number Generator
  • Advanced flash security

Integrated DC/DC Converter

  • Normal: 1.71V to 3.6V
