NXP Semiconductors MKE02Z32VLD4R

Overview

MKE02Z32VLD4R from NXP Semiconductors is a 32 KB flash, 40 MHz Arm® Cortex-M0+ microcontroller in 44-pin LQFP (10 mm × 10 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 motor control and smart sensor nodes requiring low-power deterministic timing.

For engineers reviewing the MKE02Z32VLD4R datasheet, MKE02Z32VLD4R pinout, MKE02Z32VLD4R application, or MKE02Z32VLD4R equivalent, key selection criteria include its 44-pin LQFP package compatibility, 40 MHz core/20 MHz bus clock performance, integrated LPO and FLL-based clock system, and support for SWD debug and BME bit manipulation - all validated for automotive-grade temperature operation and functional safety-aware designs.

Technical Context

The MKE02Z32VLD4R implements an Arm Cortex-M0+ core with single-cycle 32×32 multiplier and single-cycle I/O port access, paired with an ICS clock system featuring internal FLL, 31.25 kHz pre-trimmed reference, and configurable oscillator options (32.768 kHz crystal or 4–20 MHz resonator). Its power management includes Run/Wait/Stop modes with sub-100 µA Stop current (32-pin variant) and LVD/LVW thresholds programmable across high/low voltage ranges.

Peripherals include one 6-channel and two 2-channel FlexTimer/PWM modules, RTC, PIT, CRC engine, WDOG with independent clock, and serial interfaces: two SPIs, up to three UARTs, and one I²C. Analog subsystem comprises a 16-channel 12-bit SAR ADC with hardware trigger capability and two ACMPs each integrating a 6-bit DAC and programmable reference input.

FAQ

What is the maximum operating frequency of the MKE02Z32VLD4R core and bus clock?

The MKE02Z32VLD4R features an Arm Cortex-M0+ core rated for up to 40 MHz and a bus clock rated for up to 20 MHz. These frequencies are supported across the full operating voltage range (2.7–5.5 V) and temperature range (–40 to 105°C), with internal FLL trimming enabling stable 40 MHz system clock generation from the 31.25 kHz internal reference. The MKE02Z32VLD4R achieves this performance without external crystal dependency in many configurations.

Does the MKE02Z32VLD4R support debugging via Serial Wire Debug (SWD)?

Yes, the MKE02Z32VLD4R includes a dedicated Serial Wire Debug (SWD) interface with SWD_CLK and SWD_DIO pins. It supports full-speed programming, real-time register inspection, and breakpoint debugging at up to 20 MHz clock rate. The interface requires no external components and operates across the full voltage and temperature range. This capability is documented in Section 6.1.1 of the KE02 Sub-Family Data Sheet (Rev. 6, 2019) and applies specifically to the MKE02Z32VLD4R.

What are the low-power modes supported by the MKE02Z32VLD4R and their typical current consumption?

The MKE02Z32VLD4R supports Run, Wait, and Stop power modes. In Stop mode with only the 1 kHz LPO active, typical current is 2 µA at 3 V and 5 V (–40 to 105°C). With ADC enabled in Stop, consumption rises to 41–42 µA (32-pin) or 86 µA (44-/64-pin packages); with ACMP active, it adds 12 µA. These values are measured per Table 5 in the KE02 Sub-Family Data Sheet and apply directly to the MKE02Z32VLD4R in its 44-pin LQFP configuration.

Can the MKE02Z32VLD4R operate without an external crystal?

Yes, the MKE02Z32VLD4R can operate without an external crystal using its internal ICS with FLL and pre-trimmed 31.25 kHz reference. This configuration supports up to 40 MHz system clock after trimming and is fully functional across –40 to 105°C. External crystals (32.768 kHz or 4–20 MHz) are optional for higher accuracy or specific timing requirements. This capability is confirmed in the Clocks section of the KE02 Sub-Family Data Sheet and applies to the MKE02Z32VLD4R.

How many general-purpose I/O pins does the MKE02Z32VLD4R provide?

The MKE02Z32VLD4R provides up to 57 general-purpose I/O pins, distributed across ports A through E. All pins support configurable drive strength (standard or high), internal pullup/pulldown, and interrupt capability. This count is consistent across the KE02Z subfamily and explicitly confirmed for the 44-pin LQFP package (VLD) in the Human-Machine Interface section of the KE02 Sub-Family Data Sheet. The MKE02Z32VLD4R delivers this full I/O count in its specified package.
