NXP Semiconductors MKE02Z32VLC2

Overview

MKE02Z32VLC2 from NXP Semiconductors is a 32 KB flash, 20 MHz Arm® Cortex-M0+ microcontroller in 32-pin LQFP (7 mm × 7 mm), 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 sensor nodes and motor control edge devices.

For engineers reviewing the MKE02Z32VLC2 datasheet, MKE02Z32VLC2 pinout, MKE02Z32VLC2 application, or MKE02Z32VLC2 equivalent, key selection criteria include its 32-pin LQFP package footprint, 20 MHz maximum core frequency, integrated low-power RTC and Stop-mode current of 1.9–2 µA, and support for SWD debug interface with up to 20 MHz clock.

Technical Context

The MKE02Z32VLC2 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-based frequency synthesis and a pre-trimmed 31.25 kHz internal reference enabling 16–20 MHz system clocks. Its clock architecture supports multiple sources: 32.768 kHz crystal, 4–20 MHz external crystal/resonator, and internal 1 kHz LPO.

System-level integration includes Power Management Controller (PMC) with Run/Wait/Stop modes, Low-Voltage Detect (LVD) with configurable trip points (2.56–4.4 V), and programmable CRC engine. Analog subsystem comprises one 16-channel 12-bit SAR ADC with hardware trigger capability and two ACMP modules each integrating a 6-bit DAC and programmable reference input.

FAQ

What is the maximum operating frequency of the MKE02Z32VLC2 core?

The MKE02Z32VLC2 features an Arm Cortex-M0+ core rated for up to 20 MHz operation. This frequency is achieved using the Internal Clock Source (ICS) with FLL, supported by either an external 4–20 MHz crystal/resonator or the internal 31.25 kHz reference trimmed for 16–20 MHz system clock output. The MKE02Z32VLC2 datasheet specifies fSys ≤ 20 MHz under all valid VDD (2.7–5.5 V) and temperature (–40 to 105°C) conditions.

Does the MKE02Z32VLC2 support debugging via SWD, and what are the electrical requirements?

Yes, the MKE02Z32VLC2 supports Serial Wire Debug (SWD) using dedicated SWD_DIO and SWD_CLK pins. Per the KE02 Sub-Family Data Sheet Rev. 7, SWD_CLK operates up to 20 MHz, with minimum high/low pulse widths of 20 ns and rise/fall times ≤3 ns. The interface operates across the full 2.7–5.5 V supply range, and requires no external level-shifting when used with standard ARM debug probes.

What is the lowest achievable current consumption in Stop mode for the MKE02Z32VLC2?

The MKE02Z32VLC2 achieves 1.9 µA typical Stop-mode current at 3 V and 2 µA at 5 V, measured with only the 1 kHz LPO active and all other clocks disabled. This value increases by known adders: +41 µA for ADC enabled in Stop, +12 µA for ACMP, and +124–128 µA for LVD - all specified in Table 5 of the MKE02P64M20SF0 datasheet.

Can the MKE02Z32VLC2 drive standard 5 V logic inputs directly from its GPIOs?

Yes, the MKE02Z32VLC2 GPIOs support 5 V-tolerant inputs and can source/sink up to 25 mA per pin (±25 mA absolute max). When VDD = 5 V and loaded at –5 mA, VOH ≥ VDD – 0.8 V (≥4.2 V), meeting TTL and CMOS 5 V input thresholds. Output drive strength is configurable per pin, and true open-drain operation is available on PTA2/PTA3 for I²C bus compatibility.

How many analog comparator modules does the MKE02Z32VLC2 integrate, and what are their key capabilities?

The MKE02Z32VLC2 integrates two independent analog comparator modules (ACMP0 and ACMP1). Each includes differential inputs, a 6-bit DAC for programmable reference generation, selectable hysteresis, and interrupt capability. Both comparators remain functional in Stop mode and support windowed monitoring - enabling precise overvoltage/undervoltage detection and zero-crossing sensing without CPU intervention.
