Technical Context
The MKL25Z32VFT4 implements an ARM Cortex-M0+ core with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB), operating at up to 48 MHz in FEI/PEE clock modes and down to 4 MHz in VLPR mode. Its power architecture supports nine low-power states including VLLS0 (0.31 µA), VLLS1 (0.58 µA), and VLPS (3.75 µA), enabled by 90 nm TFS process, clock gating, and zero-wait-state flash.
Peripherals include one USB full-/low-speed OTG controller with integrated 5 V-to-3.3 V regulator, two UARTs, one low-power UART, two I²C modules, two SPI modules, six-channel TPM, two 2-channel TPMs, RTC, LPTMR, and analog subsystem comprising 16-bit ADC, 12-bit DAC, and comparator with 6-bit DAC reference - all accessible via 36 GPIOs in the 48-pin QFN package.
