NXP Semiconductors MKE02Z32VLD2R

Overview

MKE02Z32VLD2R from NXP Semiconductors is a 32 KB flash, 20 MHz Arm® Cortex-M0+ microcontroller in 44-pin LQFP package, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates 12-bit SAR ADC, dual analog comparators with 6-bit DACs, FlexTimer/PWM modules, and UART/I²C/SPI interfaces for embedded control in industrial sensors and motor drives.

For engineers reviewing the MKE02Z32VLD2R datasheet, MKE02Z32VLD2R pinout, MKE02Z32VLD2R application, or MKE02Z32VLD2R equivalent, key selection factors include its 32 KB flash size, 44-pin LQFP footprint, 20 MHz core clock, -40 to 105°C temperature rating, and integrated analog peripherals enabling compact, cost-sensitive MCU designs without external signal conditioning.

Technical Context

The MKE02Z32VLD2R implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O access port, paired with an Internal Clock Source (ICS) featuring FLL and pre-trimmed 31.25 kHz reference for up to 20 MHz system clock. Its clock architecture supports crystal (4–20 MHz or 32.768 kHz) or internal oscillator operation with selectable low-power/high-gain modes.

System-level integration includes Power Management Module (PMC) supporting Run/Wait/Stop modes, Low-Voltage Detection (LVD) with configurable trip points, and Serial Wire Debug (SWD) interface compliant with 0–20 MHz SWD_CLK and ≤3 ns rise/fall times. The device delivers 2 µA typical Stop mode current (5 V) and supports ADC operation in Stop mode with hardware trigger capability.

FAQ

What is the maximum operating frequency of the MKE02Z32VLD2R core?

The MKE02Z32VLD2R features an Arm Cortex-M0+ core rated for up to 20 MHz operation. This maximum frequency is achievable using the internal clock source (ICS) with FLL enabled and properly trimmed, or with an external 20 MHz crystal or resonator. System clock stability and jitter performance meet requirements for real-time control loops and communication timing in industrial and automotive applications.

Does the MKE02Z32VLD2R support debugging during development?

Yes, the MKE02Z32VLD2R includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. It supports full programming, breakpoint setting, and real-time variable inspection using standard tools like MCUXpresso IDE and J-Link debug probes. SWD_CLK operates up to 20 MHz, and the interface uses only two pins (SWD_DIO and SWD_CLK), minimizing PCB routing complexity while maintaining high-speed debug throughput.

How much flash memory does the MKE02Z32VLD2R have, and is it field-programmable?

The MKE02Z32VLD2R contains 32 KB of on-chip flash memory, which is fully field-programmable via the SWD interface or through in-application programming (IAP) routines. Flash endurance is rated for 100,000 erase/write cycles, and data retention exceeds 20 years at 85°C. The memory map includes dedicated sectors for bootloader, application, and configuration data, supporting secure firmware updates and parameter storage.

Can the MKE02Z32VLD2R operate in low-power modes with analog peripherals active?

Yes, the MKE02Z32VLD2R supports Stop mode operation with the 12-bit ADC enabled and configured for hardware-triggered conversion, drawing only 2 µA typical (5 V) supply current. The ADC can wake the core upon completion, and the independent 1 kHz Low-Power Oscillator (LPO) ensures timing accuracy during deep sleep. Analog comparators also remain functional in Stop mode, adding 12 µA typical current draw.

What package type and pin count does the MKE02Z32VLD2R use?

The MKE02Z32VLD2R uses a 44-pin LQFP package measuring 10 mm × 10 mm with 0.8 mm pitch. This package is RoHS-compliant and rated for moisture sensitivity level 3 per J-STD-020. Pin assignments include dedicated VDDA/VSSA for analog isolation, multiplexed GPIO supporting UART/I²C/SPI/FTM, and SWD debug pins-all documented in the KE02 Sub-Family Data Sheet Rev. 7.
