The supply voltage range is 1.71 V to 3.6 V, and the operating temperature range is -40°C to 105°C. ## 72 MHz Cortex-M0+ — what that means on the bench 72 MHz is the top speed for this Cortex-M0+ core. The 512 KB Flash and 128 KB RAM support a bootloader plus application code. The MKL28Z512VLL7 adds FlexIO and 82 I/O pins. The FlexIO block can emulate UART, SPI, I²C, or a custom parallel bus with programmable timing.","metaTitle":"NXP MKL28Z512VLL7 Kinetis KL2 MCU, ARM Cortex-M0+, 72 MHz, 512 KB Flash","metaDescription":"NXP MKL28Z512VLL7 32-bit ARM Cortex-M0+ MCU, 72 MHz core, 512 KB Flash, 128 KB RAM, USB & FlexIO, -40 to 105°C.
