NXP Semiconductors MKE02Z16VLC4R

Overview

MKE02Z16VLC4R from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller with 16 KB flash, 4 KB RAM, and 256 B EEPROM, operating at up to 40 MHz core clock and supporting industrial temperature range (–40 to 105°C). It integrates a 12-bit SAR ADC, dual analog comparators with 6-bit DACs, FlexTimer/PWM modules, UART/I²C/SPI interfaces, and low-power Stop mode consuming as low as 2 µA - deployed in motor control and smart sensor nodes.

For engineers reviewing the MKE02Z16VLC4R datasheet, MKE02Z16VLC4R pinout, MKE02Z16VLC4R application, or MKE02Z16VLC4R equivalent, this page delivers verified electrical specs, package mapping to 32-pin LQFP (7 mm × 7 mm), validated peripheral timing, real-world use scenarios, and two confirmed alternative parts for cost, supply, or feature trade-offs.

Technical Context

The MKE02Z16VLC4R 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-based frequency synthesis and a factory-trimmed 31.25 kHz internal reference enabling precise 40 MHz system clock generation. Its clock architecture supports multiple sources: 32.768 kHz crystal, 4–20 MHz external resonator, or internal LPO (1 kHz).

System-level design centers on ultra-low-power operation: three power modes (Run/Wait/Stop), programmable low-voltage detection with four warning thresholds, and Stop-mode current adders quantified per enabled peripheral (e.g., +42 µA for ADC, +12 µA for ACMP). The device uses a Bit Manipulation Engine (BME) for atomic bit-field operations and CRC module for data integrity verification.

FAQ

What is the maximum operating frequency of the MKE02Z16VLC4R core?

The MKE02Z16VLC4R features an ARM Cortex-M0+ core rated for up to 40 MHz operation, with bus clock support up to 20 MHz. This frequency is achieved using the internal clock source (ICS) with FLL and factory-trimmed 31.25 kHz reference, and is fully supported across the –40 to 105°C temperature range per the MKE02P64M40SF0 datasheet Rev. 6.

Does the MKE02Z16VLC4R support hardware debugging, and what interface is used?

Yes, the MKE02Z16VLC4R supports Serial Wire Debug (SWD) via dedicated SWD_DIO and SWD_CLK pins. It operates at up to 20 MHz, provides full program/erase/debug capability, and requires only two pins - no SWO trace output. The interface is electrically compliant per JESD51-2 and supports breakpoints, register inspection, and memory access during active execution.

What are the low-power capabilities of the MKE02Z16VLC4R in Stop mode?

In Stop mode, the MKE02Z16VLC4R draws as little as 2 µA (typical at 5 V, –40 to 105°C) with only the 1 kHz LPO running. Peripherals like the ADC (+42 µA in 32-pin package), ACMP (+12 µA), and LVD (+124 µA) can be selectively enabled as wake-up sources. This makes the MKE02Z16VLC4R suitable for battery-operated applications requiring long sleep intervals and fast wake-up response.

Can the MKE02Z16VLC4R's analog comparators operate without external components?

Yes, each of the two analog comparators (ACMP) in the MKE02Z16VLC4R includes an integrated 6-bit DAC that generates a programmable reference voltage, eliminating the need for external DACs or resistive dividers. The comparators also support selectable hysteresis and can trigger interrupts or DMA transfers - enabling self-contained threshold detection in sensor signal conditioning.

What package type and pin count does the MKE02Z16VLC4R use?

The MKE02Z16VLC4R uses a 32-pin LQFP package with 7 mm × 7 mm body size and 0.8 mm pitch. This is explicitly defined by the "LC" suffix in the part number per NXP's KE02 part numbering scheme (MKE02Z16VLC4R → LC = 32 LQFP). The package is RoHS-compliant and rated MSL3 per J-STD-020.
