NXP Semiconductors MKE02Z32VLH2

Overview

MKE02Z32VLH2 from NXP Semiconductors is a 32 KB flash, 20 MHz Arm® Cortex-M0+ microcontroller in 64-pin LQFP package, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates 4 KB RAM, 256 B EEPROM, 12-bit SAR ADC with Stop-mode operation, dual analog comparators with 6-bit DACs, and three UARTs - deployed in industrial motor control subsystems requiring deterministic real-time response and low-power sleep modes.

For engineers reviewing the MKE02Z32VLH2 datasheet, MKE02Z32VLH2 pinout, MKE02Z32VLH2 application, or MKE02Z32VLH2 equivalent, key selection criteria include its 64-pin LQFP thermal performance (RθJA = 53°C/W on 4-layer board), 2 µA Stop-mode current at 3 V, FTM-based PWM timing precision, SWD debug interface compliance, and compatibility with KE02Z family toolchains and peripheral drivers.

Technical Context

The MKE02Z32VLH2 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access, enabling deterministic interrupt latency for time-critical control loops. Its internal clock system combines an FLL with trimmable 31.25 kHz reference for up to 20 MHz system clock, plus independent 1 kHz LPO for RTC and low-power wake-up.

Peripherals include one 6-channel and two 2-channel FlexTimer/PWM modules supporting edge-aligned and center-aligned PWM generation, a periodic interrupt timer (PIT) for OS tick, and a real-time clock (RTC) with calendar support. Analog subsystem comprises a 16-channel 12-bit SAR ADC with hardware trigger capability and two ACMPs each integrating a 6-bit DAC and programmable reference input.

FAQ

What is the maximum operating frequency of the MKE02Z32VLH2?

The MKE02Z32VLH2 operates at a maximum core and bus frequency of 20 MHz, achieved via its internal FLL with factory-trimmed 31.25 kHz reference. This frequency is fully supported across the –40 to 105°C temperature range and 2.7–5.5 V supply, and is confirmed in the KE02 Sub-Family Data Sheet Rev. 7 section 5.2.1. The MKE02Z32VLH2 does not support overclocking beyond 20 MHz.

Does the MKE02Z32VLH2 support debugging via SWD?

Yes, the MKE02Z32VLH2 includes a Serial Wire Debug (SWD) interface with dedicated SWD_CLK and SWD_DIO pins, compliant with ARM CoreSight specifications. It supports full-speed debug at up to 20 MHz, real-time trace, flash programming, and non-intrusive breakpoints - all documented in section 6.1.1 of the KE02 Sub-Family Data Sheet Rev. 7.

What is the Stop mode current consumption of the MKE02Z32VLH2?

The MKE02Z32VLH2 achieves 2 µA typical Stop mode current at 3 V and –40 to 105°C, as specified in Table 5 of the KE02 Sub-Family Data Sheet Rev. 7. This value assumes only the 1 kHz LPO clock active; adding ADC, ACMP, or LVD increases current by 42–128 µA depending on configuration and package.

Which package type does the MKE02Z32VLH2 use?

The MKE02Z32VLH2 uses a 64-pin LQFP package (10 mm × 10 mm), identified by the "LH" suffix in its part number per NXP's KE02Z naming convention. This matches the "PP" field definition in section 2.3 of the KE02 Sub-Family Data Sheet Rev. 7 and is distinct from QH (64-pin QFP) and LD/LC variants.

Can the MKE02Z32VLH2 operate from a 3.3 V supply?

Yes, the MKE02Z32VLH2 is fully specified to operate from 2.7 V to 5.5 V, including standard 3.3 V nominal supplies. All electrical characteristics - including IOH/VOL, ADC accuracy, and Flash write - are guaranteed across this range per Table 3 and Table 4 in the KE02 Sub-Family Data Sheet Rev. 7.
