Product details
Overview
MKE02Z64VLH4 from NXP Semiconductors is a 40 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, six FTM/PWM channels, RTC, and SWD debug-targeted for industrial motor control, smart sensors, and battery-powered embedded systems.
For engineers reviewing the MKE02Z64VLH4 datasheet, MKE02Z64VLH4 pinout, MKE02Z64VLH4 application, or MKE02Z64VLH4 equivalent, key selection criteria include its 64-pin LQFP package, 40 MHz core clock, low-power Stop mode (2 µA), integrated ACMP with programmable reference, and UART/SPI/I²C interface count for resource-constrained edge nodes.
Technical Context
The MKE02Z64VLH4 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access. Its clock system combines an external 4–20 MHz crystal oscillator with an internal FLL and pre-trimmed 31.25 kHz reference, enabling up to 40 MHz system clock with optional trimming.
Peripherals include three UART modules (one with LIN support), two SPI interfaces, one I²C controller, and a programmable cyclic redundancy check (CRC) engine. Power management supports Run, Wait, and Stop modes-with Stop mode retaining RAM and enabling wake-up via ADC, ACMP, or IRQ while drawing only 2 µA at 5 V.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE02Z64VQH4 | Identical core, memory, and peripherals; differs only in 64-pin QFP (14 mm × 14 mm) vs. LQFP (10 mm × 10 mm) package | Same functionality but larger PCB footprint and higher thermal resistance (RθJA = 61°C/W vs. 53°C/W on 4-layer board) | Select MKE02Z64VQH4 only if legacy QFP tooling or mechanical clearance requires larger package |

FAQ
What is the maximum operating frequency of the MKE02Z64VLH4 core and bus clocks?
The MKE02Z64VLH4 features an Arm Cortex-M0+ core rated for up to 40 MHz and a bus clock up to 20 MHz. This is achieved using the internal FLL with either an external 4–20 MHz crystal or the factory-trimmed 31.25 kHz internal reference, which can be adjusted to support the full 40 MHz system clock. The MKE02Z64VLH4 datasheet specifies these frequencies under all operating voltage (2.7–5.5 V) and temperature (–40 to 105°C) conditions.
Does the MKE02Z64VLH4 support debugging via Serial Wire Debug (SWD)?
Yes, the MKE02Z64VLH4 includes a dedicated Serial Wire Debug (SWD) interface with SWD_CLK and SWD_DIO pins, supporting programming and real-time debugging at up to 20 MHz. The interface operates across the full 2.7–5.5 V supply range and requires no additional pins beyond the two SWD signals and power/ground. This capability is documented in Section 6.1.1 of the MKE02Z64VLH4 datasheet and verified on NXP's official KE02 evaluation boards.
What is the lowest power consumption mode available on the MKE02Z64VLH4, and what peripherals remain active?
The MKE02Z64VLH4 achieves 2 µA typical current in Stop mode with only the 1 kHz LPO clock active. In this state, RAM contents are retained, and wake-up is supported via RTC alarm, ADC conversion completion, analog comparator output, or external IRQ. The MKE02Z64VLH4 datasheet Table 5 confirms this value at 5 V and –40 to 105°C, with adders specified for enabling ADC (86 µA), ACMP (12 µA), or LVD (128 µA) during Stop.
How many analog-to-digital converter (ADC) channels does the MKE02Z64VLH4 support, and what is its resolution?
The MKE02Z64VLH4 integrates a single 12-bit successive approximation register (SAR) ADC with up to 16 input channels. It supports hardware-triggered conversions in Stop mode and offers programmable sample time, conversion speed, and reference selection (VREFH/VREFL or internal bandgap). These specifications are confirmed in Section 5.2.1 of the MKE02Z64VLH4 datasheet and apply identically across all KE02Z64 variants including the MKE02Z64VLH4.
What package type and pin count does the MKE02Z64VLH4 use, and is it RoHS-compliant?
The MKE02Z64VLH4 uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) and is fully RoHS-compliant per EU Directive 2011/65/EU. Its package identifier "LH" in the part number explicitly denotes this variant, and the device meets moisture sensitivity level 3 (MSL3) per J-STD-020. This information is defined in Section 2.3 of the MKE02Z64VLH4 datasheet and validated through NXP's official packaging documentation.
