Product details
Overview
MKE02Z64VFM4R from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller in a 32-pin QFN (5 mm × 5 mm) package, operating at up to 40 MHz core frequency with 64 KB flash, 4 KB RAM, and -40°C to +105°C industrial temperature range. It integrates a 12-bit SAR ADC, dual analog comparators with 6-bit DACs, FlexTimer/PWM modules, UART/I²C/SPI interfaces, and low-power Stop mode consuming as low as 1.9 µA (3 V), targeting cost-sensitive motor control and sensor interface applications.
For engineers reviewing the MKE02Z64VFM4R datasheet, MKE02Z64VFM4R pinout, MKE02Z64VFM4R application, or MKE02Z64VFM4R equivalent, key selection considerations include its 32-pin QFN footprint, 64 KB flash/4 KB RAM memory configuration, 40 MHz Cortex-M0+ performance, integrated analog peripherals (ADC + ACMP), and support for industrial-grade operation across -40°C to +105°C ambient conditions.
Technical Context
The MKE02Z64VFM4R implements an ARM Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access, paired with an internal clock system (ICS) featuring FLL-based frequency synthesis from internal 31.25 kHz reference or external crystal (4–20 MHz or 32.768 kHz). Its power management includes Run/Wait/Stop modes, with Stop mode retaining RAM and supporting wake-up via ADC, ACMP, or LPO-triggered events.
Peripheral integration includes one 6-channel and two 2-channel FlexTimer/PWM modules, one RTC, two SPI, up to three UART, one I²C, 57 GPIOs (with keyboard interrupt support), and programmable CRC and bit manipulation engine (BME) - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE02Z64VLC4R | 32-pin LQFP (7 mm × 7 mm) package; identical core/peripherals but larger footprint and higher thermal resistance (RθJA = 86°C/W, 1S board) | Better suited for prototyping or manual soldering due to gull-wing leads; less optimal for high-density automated assembly | Select when board layout prioritizes hand-solderability or thermal margin over size constraints |
| MKE02Z64VLD4R | 44-pin LQFP (10 mm × 10 mm); adds 10 extra GPIOs and second UART channel vs. MKE02Z64VFM4R's 32-pin QFN | Required where additional serial interfaces or I/O expansion is needed without external logic | Choose when system demands >57 GPIOs or dual UARTs, accepting larger PCB area and higher cost |
Compared with MKE02Z64VLC4R and MKE02Z64VLD4R, the MKE02Z64VFM4R offers the smallest footprint and lowest thermal resistance among 64 KB KE02 variants, making it optimal for space- and power-constrained designs where pin count suffices and QFN reflow is supported.

FAQ
What is the maximum operating frequency of the MKE02Z64VFM4R core?
The MKE02Z64VFM4R features an ARM Cortex-M0+ core rated for up to 40 MHz operation, with corresponding bus clock up to 20 MHz. This frequency is achievable using the internal FLL driven by the factory-trimmed 31.25 kHz reference or an external 4–20 MHz crystal, and is validated across the full -40°C to +105°C temperature range and 2.7–5.5 V supply.
Does the MKE02Z64VFM4R support debugging during development?
Yes, the MKE02Z64VFM4R includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, using only two pins (SWD_CLK and SWD_DIO). It supports full-speed debugging at up to 20 MHz, flash programming, real-time variable inspection, and breakpoint management via standard tools like MCUXpresso IDE and J-Link debug probes.
What analog peripherals are integrated into the MKE02Z64VFM4R?
The MKE02Z64VFM4R integrates a 12-bit SAR ADC with up to 16 input channels and operation in Stop mode, plus two analog comparators (ACMP) each with a 6-bit DAC for programmable reference generation and hysteresis control. These are fully functional across the industrial temperature range and require separate VDDA/VSSA filtering for optimal performance.
What is the minimum supply current in low-power mode for the MKE02Z64VFM4R?
In Stop mode with RAM retention and no active peripherals, the MKE02Z64VFM4R draws as little as 1.9 µA at 3 V and -40°C to +105°C ambient. With ADC enabled in Stop, current increases to 41 µA (32-pin package), and with ACMP active, it adds 12 µA - all values specified in the official KE02 Sub-Family Data Sheet Rev. 6.
Is the MKE02Z64VFM4R pin-compatible with other KE02 family members?
No - the MKE02Z64VFM4R uses a 32-pin QFN package (FM suffix), while other variants like MKE02Z64VLC4R (LC) and MKE02Z64VLD4R (LD) use different LQFP footprints with distinct pin counts and assignments. Pin mapping, power pin locations, and peripheral multiplexing differ between packages; PCB layout is not interchangeable.
