Product details
Overview
MKL04Z32VFM4R from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M0+ microcontroller in 32-pin QFN package, delivering 48 MHz operation, 32 KB flash, 4 KB SRAM, and ultra-low-power operation down to 0.3 µA in VLLS0 mode. It integrates ADC, comparator with 6-bit DAC, SPI, I²C, UART, six-channel TPM, RTC, and SWD debug interface for compact embedded control applications.
For engineers reviewing the MKL04Z32VFM4R datasheet, MKL04Z32VFM4R pinout, MKL04Z32VFM4R application, or MKL04Z32VFM4R equivalent, key selection criteria include its 32-pin QFN footprint, -40°C to +105°C industrial temperature range, 1.71–3.6 V supply, nine low-power modes, and verified compatibility with Kinetis KL04 software enablement tools and MCUXpresso IDE.
Technical Context
The MKL04Z32VFM4R implements an ARM Cortex-M0+ core with Bit Manipulation Engine and Micro Trace Buffer, paired with a multi-mode clock system including internal 4 MHz/32 kHz IRCs and external crystal support (32 kHz–32 MHz). Its power architecture features clock gating, dynamic voltage scaling, and nine configurable low-power modes-VLLS0 through RUN-with sub-µA retention states and <4.4 µs wakeup from VLPS/STOP.
Peripheral integration includes a 12-bit SAR ADC with hardware averaging, analog comparator with programmable reference and integrated 6-bit DAC, dual TPM modules (6-channel + 2-channel), LPTMR, real-time clock with alarm, and communication interfaces supporting SPI master/slave, I²C master/slave, and low-power UART with automatic baud rate detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L031K6T6 | 32 MHz Cortex-M0+, 32 KB flash, 8 KB SRAM, 16-pin QFN - higher SRAM but fewer GPIOs (15) and no integrated DAC | Lacks comparator+DAC; requires external reference for analog thresholding; better suited for pure digital control with memory headroom | Select when SRAM demand exceeds 4 KB or when ST's CubeMX ecosystem is preferred over MCUXpresso |
| EFM32ZG108F32 | 24 MHz Cortex-M0+, 32 KB flash, 4 KB SRAM, 24-pin QFN - lower core speed, no DAC, but deeper EM4 sleep (0.18 µA) | Superior deep-sleep current but limited analog capability; lacks hardware BME and has no 6-channel TPM | Select for ultra-long-life battery applications where analog functionality is minimal and core speed <24 MHz suffices |
Compared with STM32L031K6T6 and EFM32ZG108F32, MKL04Z32VFM4R uniquely combines 48 MHz performance, integrated comparator+DAC, 28 GPIOs, and sub-µA VLLS0 mode in a 32-pin QFN - making it optimal for cost-sensitive, analog-rich, battery-operated edge nodes requiring rapid response and long service life.

FAQ
What is the maximum operating frequency of the MKL04Z32VFM4R?
The MKL04Z32VFM4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is achievable with the internal FLL locked to a 4 MHz IRC or with an external crystal source. In very-low-power run (VLPR) mode, the maximum core clock is 4 MHz to maintain sub-200 µA current draw, as specified in the Freescale KL04P48M48SF1 datasheet Rev 4.
Does the MKL04Z32VFM4R support external crystal oscillators?
Yes, the MKL04Z32VFM4R supports external crystals on XTAL0/EXTAL0 pins for both low-frequency (32–40 kHz) and high-frequency (3–32 MHz) operation. The MCG module allows configuration as FBE (external crystal enabled) or FEE (external crystal + FLL) mode. Crystal startup time and stability requirements are detailed in Section 3.3.2 of the KL04P48M48SF1 datasheet.
How many GPIO pins does the MKL04Z32VFM4R provide?
The MKL04Z32VFM4R provides 28 general-purpose I/O pins, confirmed by the "Ordering Information" table in the KL04P48M48SF1 datasheet listing "Maximum number of I/O's = 28" for part numbers ending in VFM4. These pins support multiple functions including UART, SPI, I²C, TPM, ADC, and comparator inputs, with programmable pull-up/down and slew rate control.
What low-power modes are available on the MKL04Z32VFM4R?
The MKL04Z32VFM4R offers nine distinct low-power modes: RUN, WAIT, STOP, VLPS, LLS, VLLS0, VLLS1, VLLS2, and VLLS3. VLLS0 achieves 0.3 µA current at 3 V with full RAM retention and 4 µs wakeup; VLLS3 draws 1.16 µA and retains only core registers. Mode selection is controlled via SMC registers and documented in Section 2.2.4 of the KL04P48M48SF1 datasheet.
Is the MKL04Z32VFM4R pin-compatible with other Kinetis KL04 variants?
Yes, the MKL04Z32VFM4R shares identical pinout and electrical characteristics with other MKL04ZxxVFM4 variants (e.g., MKL04Z8VFM4, MKL04Z16VFM4) in the same 32-pin QFN (VFM) package. Flash and RAM sizes differ across variants, but PCB layout, power delivery, and peripheral routing remain interchangeable - enabling scalable firmware deployment across memory configurations.
