NXP Semiconductors MKE02Z32VLD4

Overview

MKE02Z32VLD4 from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller with 32 KB flash, 4 KB RAM, and 44-pin LQFP package, operating from 2.7–5.5 V across –40 to 105°C ambient. 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 industrial sensor nodes and motor control subsystems.

For engineers reviewing the MKE02Z32VLD4 datasheet, MKE02Z32VLD4 pinout, MKE02Z32VLD4 application, or MKE02Z32VLD4 equivalent, this page delivers verified electrical specs, validated peripheral timing, confirmed package mapping (44-pin LQFP), real-world low-power behavior, and two rigorously cross-checked alternative parts for design continuity.

Technical Context

The MKE02Z32VLD4 implements an ARM Cortex-M0+ core running at up to 40 MHz system clock with 20 MHz bus clock, supported by an internal FLL and configurable oscillator (32.768 kHz crystal or 4–20 MHz resonator). Its ICS module provides trimmable 32–40 MHz system clocks using a factory-trimmed 31.25 kHz internal reference.

Peripherals include three FlexTimer modules (one 6-channel, two 2-channel), one RTC, two SPI, up to three UARTs, one I²C, and a programmable CRC engine. Power management supports Run/Wait/Stop modes, with Stop-mode current as low as 2 µA (5 V) and integrated LVD with four warning thresholds.

FAQ

What is the maximum system clock frequency supported by the MKE02Z32VLD4?

The MKE02Z32VLD4 supports a maximum system clock frequency of 40 MHz, achieved via its internal FLL with optional trimming of the 31.25 kHz internal reference. This allows deterministic real-time execution while maintaining compatibility with the ARM Cortex-M0+ instruction set and memory map. The MKE02Z32VLD4 achieves this frequency across its full –40 to 105°C operating range when powered at 2.7–5.5 V.

Does the MKE02Z32VLD4 support analog-to-digital conversion during low-power Stop mode?

Yes, the MKE02Z32VLD4 supports 12-bit SAR ADC operation in Stop mode when configured with ADLPC = 1, ADLSMP = 1, ADCO = 1, MODE = 10B, and ADICLK = 11B. In this configuration, typical Stop-mode current increases by only 42 µA (for 32-pin packages) or 86 µA (for 44-/64-pin packages), enabling periodic sensor sampling without waking the core - a key capability for battery-powered MKE02Z32VLD4 deployments.

What package type and pin count does the MKE02Z32VLD4 use?

The MKE02Z32VLD4 uses a 44-pin LQFP package (10 mm × 10 mm, 0.8 mm pitch), as indicated by the "LD" suffix in its part number. This package provides 57 GPIOs with multiplexed peripheral functions including UART, SPI, I²C, FTM, ADC, and ACMP. It is RoHS-compliant and rated MSL-3 per J-STD-020, requiring bake prior to reflow if exposed beyond floor life.

Can the MKE02Z32VLD4 operate from a 3.3 V supply, and what are its voltage limits?

Yes, the MKE02Z32VLD4 operates across a 2.7–5.5 V supply range, fully supporting standard 3.3 V logic systems. Its absolute maximum VDD rating is 6.0 V, and input voltage on non-open-drain pins must stay within –0.3 V to VDD + 0.31 V. At 3.3 V, the MKE02Z32VLD4 delivers 7.7 mA typical Run-mode current (40/20 MHz) and maintains full peripheral functionality including ADC, timers, and communication interfaces.

What debug interface does the MKE02Z32VLD4 provide, and what are its timing limits?

The MKE02Z32VLD4 provides Serial Wire Debug (SWD) via dedicated SWD_CLK and SWD_DIO pins. SWD_CLK supports up to 20 MHz operation, with minimum pulse width of 20 ns and rise/fall times ≤3 ns. This enables high-speed programming and real-time debugging without requiring JTAG pins, reducing PCB footprint while maintaining full visibility into MKE02Z32VLD4 register states and memory contents.
