Product details
Overview
MKL15Z64VFM4R from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M0+ microcontroller in 32-pin QFN package, operating up to 48 MHz with 64 KB flash, 8 KB SRAM, and ultra-low-power operation down to 0.31 µA in VLLS0 mode. It integrates 16-bit SAR ADC, 12-bit DAC, two UARTs, two I²C, two SPI, TSI touch interface, and six-channel TPM - deployed in battery-powered sensor nodes and portable medical devices.
For engineers reviewing the MKL15Z64VFM4R datasheet, MKL15Z64VFM4R pinout, MKL15Z64VFM4R application, or MKL15Z64VFM4R equivalent, key selection criteria include its 32-pin QFN footprint, -40°C to +105°C industrial temperature rating, 1.71–3.6 V supply range, low-power run/wake timing (4 µs wakeup from VLPS), and compatibility with Kinetis L-family toolchains and SDKs.
Technical Context
The MKL15Z64VFM4R implements an ARM Cortex-M0+ core with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB) for debug visibility. Its clock system includes multi-mode MCG (FEI/FBI/BLPI/PEE) supporting internal 4 MHz IRC, external 32 kHz crystal, and 4–16 MHz high-frequency crystals - enabling dynamic power/performance scaling across nine low-power modes.
Peripherals are partitioned into always-on (LPTMR, RTC, CMP), low-leakage (TSI, ADC in VLPR), and gated domains (UART, SPI, I²C). Memory subsystem features zero-wait-state flash with RDC protection, 8 KB SRAM with retention in LLS/VLLS modes, and dedicated DMA supporting 63 request sources - optimized for deterministic real-time response in energy-constrained edge nodes.

FAQ
What is the maximum operating frequency of the MKL15Z64VFM4R?
The MKL15Z64VFM4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is achievable using the PEE clock mode with an external 4–16 MHz crystal oscillator and proper MCG configuration. In very-low-power run (VLPR) mode, the maximum core clock is 4 MHz - a trade-off enabling sub-500 µA active current while retaining full peripheral functionality.
Does the MKL15Z64VFM4R support hardware touch sensing?
Yes, the MKL15Z64VFM4R integrates a dedicated Touch Sensing Interface (TSI) module supporting up to 16 capacitive sensing channels. It operates independently of the CPU in low-power modes, providing automatic scanning, noise filtering, and baseline tracking - enabling robust button, slider, and proximity detection without firmware intervention or external components.
What are the key low-power modes supported by the MKL15Z64VFM4R?
The MKL15Z64VFM4R implements nine distinct low-power modes: RUN, WAIT, STOP, VLPS, LLS, and three VLLS variants (VLLS0–VLLS3). VLLS0 achieves 0.31 µA typical current with full register retention and 4 µs wake time, while VLPS maintains 123–366 µA with CPU halted but peripherals like LPTMR and ADC active - enabling flexible power/performance tuning for diverse battery-life targets.
Can the MKL15Z64VFM4R operate across the full industrial temperature range?
Yes, the MKL15Z64VFM4R is specified for operation from -40°C to +105°C ambient temperature. This rating is validated across all electrical parameters including flash programming, ADC accuracy, and clock stability - making it suitable for under-hood automotive modules, factory-floor sensors, and outdoor industrial gateways without derating or thermal management overhead.
What debug interfaces does the MKL15Z64VFM4R provide?
The MKL15Z64VFM4R supports Serial Wire Debug (SWD) with Micro Trace Buffer (MTB) for real-time instruction trace and profiling. It includes a COP (Computer Operating Properly) watchdog timer and NVIC-based exception handling. No JTAG interface is present - SWD is the sole standardized debug access method, compatible with standard ARM Cortex-M debug probes and MCUXpresso IDE.
