NXP Semiconductors MKE02Z64VQH2

Overview

MKE02Z64VQH2 from NXP Semiconductors is a 20 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 4 KB RAM, and 256 B EEPROM, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates dual 12-bit ADCs, two analog comparators with 6-bit DACs, three UARTs, two SPIs, one I²C, six FTM timer channels, RTC, and SWD debug - deployed in industrial motor control, smart sensors, and battery-powered HMI systems.

For engineers reviewing the MKE02Z64VQH2 datasheet, MKE02Z64VQH2 pinout, MKE02Z64VQH2 application, or MKE02Z64VQH2 equivalent, key selection criteria include its 64-pin QFP package, 20 MHz max core frequency, Stop-mode current as low as 1.9 µA (3 V), LVD/LVW thresholds with hysteresis, and support for crystal oscillators up to 20 MHz or internal FLL-based clocking.

Technical Context

The MKE02Z64VQH2 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiply and single-cycle I/O port access, paired with an Internal Clock Source (ICS) featuring FLL and pre-trimmed 31.25 kHz reference enabling precise 16–20 MHz system clocks. Its oscillator supports both low-power and high-gain modes for 32.768 kHz crystals or 4–20 MHz resonators.

System-level timing relies on three independent FlexTimer modules (one 6-channel + two 2-channel), a periodic interrupt timer (PIT), and real-time clock (RTC) with 1 kHz LPO backup. Analog subsystem includes a 16-channel 12-bit SAR ADC operational in Stop mode and two ACMPs with programmable reference inputs and integrated 6-bit DACs.

FAQ

What is the maximum operating frequency of the MKE02Z64VQH2 core?

The MKE02Z64VQH2 features an Arm Cortex-M0+ core rated for up to 20 MHz operation. This frequency is achievable using either the internal FLL (with internal 31.25 kHz reference trimmed for 20 MHz output) or an external 20 MHz crystal/resonator. The bus clock runs synchronously at the same rate, enabling deterministic peripheral timing and single-cycle I/O access.

Does the MKE02Z64VQH2 support crystal oscillators below 1 MHz?

Yes, the MKE02Z64VQH2 supports 32.768 kHz crystals via its OSC module in low-range mode (flo = 31.25–39.0625 kHz), commonly used for RTC backup. It does not support crystals below ~31 kHz; for sub-kHz timing, the internal 1 kHz LPO oscillator is used instead - characterized at 0.67–1.25 kHz across temperature and voltage.

How much current does the MKE02Z64VQH2 draw in Stop mode with RTC and ADC enabled?

In Stop mode with only the 1 kHz LPO active, the MKE02Z64VQH2 draws 1.9 µA typical at 3 V (–40 to 105°C). Enabling RTC adds <1 µA; enabling ADC in low-power continuous mode adds 42 µA (64-pin package) or 86 µA (32-pin package) - so total Stop current with RTC + ADC is ~44 µA typical at 3 V.

Can the MKE02Z64VQH2's analog comparators operate during Stop mode?

Yes, the two analog comparators (ACMP) in the MKE02Z64VQH2 remain functional in Stop mode and consume only 12 µA typical (5 V) or 12 µA (3 V). Each ACMP includes a 6-bit DAC for programmable reference voltage generation and supports interrupt generation on output transitions - enabling wake-from-Stop on analog threshold events.

Is the MKE02Z64VQH2 pin-compatible with other KE02Z variants in the same package?

Yes, all KE02Z devices in the 64-pin QFP (QH) package - including MKE02Z16VQH2, MKE02Z32VQH2, and MKE02Z64VQH2 - share identical pinouts and electrical characteristics. Firmware and hardware designs are interchangeable across flash sizes; only memory map and feature enablement differ in software configuration.
