NXP Semiconductors MKE02Z16VLD2

Overview

MKE02Z16VLD2 from NXP Semiconductors is a 20 MHz Arm® Cortex-M0+ microcontroller with 16 KB flash, 4 KB RAM, and 256 B EEPROM, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates a 12-bit SAR ADC (16-channel), dual analog comparators with 6-bit DACs, FlexTimer/PWM modules, RTC, and serial interfaces (SPI, UART, I²C) for embedded control in industrial sensors and motor drives.

For engineers reviewing the MKE02Z16VLD2 datasheet, MKE02Z16VLD2 pinout, MKE02Z16VLD2 application, or MKE02Z16VLD2 equivalent, key selection criteria include its 44-pin LQFP package, 20 MHz core clock, low-power Stop mode (2 µA typical), integrated LVD/ACMP/FTM peripherals, and support for crystal oscillators up to 20 MHz - all validated for automotive-grade temperature operation.

Technical Context

The MKE02Z16VLD2 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiply and single-cycle I/O access, paired with an Internal Clock Source (ICS) featuring FLL-based frequency synthesis and a pre-trimmed 31.25 kHz internal reference enabling precise 16–20 MHz system clocks. Its power management includes Run/Wait/Stop modes, with Stop mode retaining RAM and supporting wake-up via ADC, ACMP, or LVD.

Peripherals are tightly coupled to the bus architecture: two SPI modules operate at up to 20 MHz bus clock, three UARTs support asynchronous communication with configurable baud rates, and the I²C module complies with standard-mode (100 kbps) and fast-mode (400 kbps) specifications. The 12-bit ADC supports hardware-triggered conversions in Stop mode, while dual ACMPs provide programmable reference inputs and 6-bit DAC outputs for comparator hysteresis or threshold generation.

FAQ

What is the maximum operating frequency of the MKE02Z16VLD2 core?

The MKE02Z16VLD2 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 factory-trimmed 31.25 kHz internal reference. System clock stability meets automotive-grade requirements across –40 to 105°C ambient.

Does the MKE02Z16VLD2 support debugging during low-power modes?

Yes, the MKE02Z16VLD2 supports Serial Wire Debug (SWD) in Run, Wait, and Stop modes. SWD_CLK operates up to 20 MHz, and the interface remains accessible even when the core is halted or in Stop mode - enabling breakpoints, register inspection, and flash programming without exiting low-power states. This capability is critical for optimizing power consumption in battery-operated designs using MKE02Z16VLD2.

What analog peripherals are integrated into the MKE02Z16VLD2?

The MKE02Z16VLD2 integrates a 12-bit SAR ADC with up to 16 input channels, two analog comparators (ACMP) each with a 6-bit DAC and programmable reference input, and a buffered bandgap voltage reference (1.16 V typical). The ADC supports hardware triggering and operation in Stop mode, while ACMPs enable zero-crossing detection, windowed monitoring, and hysteresis control - all verified for use across the full –40 to 105°C temperature range.

Can the MKE02Z16VLD2 operate from a single 3.3 V supply?

Yes, the MKE02Z16VLD2 operates over a supply range of 2.7–5.5 V, fully supporting 3.3 V nominal systems. At 3.3 V, it delivers 20 MHz core performance, maintains full peripheral functionality (including ADC accuracy and UART timing), and achieves 5.3 mA typical Run mode current and 2 µA Stop mode current. All I/O pins are 5 V tolerant when configured as inputs, simplifying interface with legacy 5 V logic.

What package type and pin count does the MKE02Z16VLD2 use?

The MKE02Z16VLD2 uses a 44-pin LQFP package (10 mm × 10 mm, 0.8 mm pitch), designated by the "LD" suffix in its part number. This RoHS-compliant package has moisture sensitivity level 3 and supports reflow soldering per J-STD-020. Pin assignments are documented in Section 8 of the KE02 Sub-Family Data Sheet (Rev. 7), with signal multiplexing defined for all 57 GPIOs and dedicated power/ground/debug pins.
