Product details
Overview
MKL15Z128VFM4R from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM® Cortex®-M0+ based microcontroller in the Kinetis KL15 sub-family, designed for ultra-low-power embedded applications. It integrates 128 KB flash, 16 KB SRAM, a 16-bit SAR ADC, 12-bit DAC, and two UARTs - enabling compact sensor nodes, battery-powered HMI interfaces, and industrial control peripherals.
For engineers reviewing the MKL15Z128VFM4R datasheet, MKL15Z128VFM4R pinout, MKL15Z128VFM4R application, or MKL15Z128VFM4R equivalent, this page delivers verified technical context, low-power mode behavior, QFN-32 package mapping, real-world use cases, and validated alternative parts - all grounded in the KL15P80M48SF0 Rev 5 datasheet and official package drawings.
Technical Context
The MKL15Z128VFM4R implements an energy-optimized Cortex-M0+ core with nine configurable low-power modes, including VLLS0 (0.12 µA typical at 25°C with PORPO=1) and VLPR (204 µA typical at 3.0 V). Its clock system supports multiple sources: internal 4 MHz IRC, 32 kHz LPO, and external crystals up to 16 MHz, managed by the MCG module in FEI, FBE, BLPI, and BLPE modes.
Peripherals include a 6-channel TPM timer, two 2-channel TPM modules, LPTMR, RTC, COP watchdog, and a Bit Manipulation Engine (BME) for atomic bit-field operations. Analog integration comprises a 16-bit ADC with hardware averaging, 12-bit DAC, and a comparator with integrated 6-bit DAC reference - all operating across –40°C to +105°C ambient temperature.
