NXP Semiconductors MKE04Z8VWJ4

Overview

MKE04Z8VWJ4 from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 8 KB flash, 1 KB RAM, and integrated analog peripherals including a 12-bit SAR ADC and dual analog comparators-designed for cost-sensitive industrial control and sensor interface applications in SOIC-20 packaging.

For engineers reviewing the MKE04Z8VWJ4 datasheet, MKE04Z8VWJ4 pinout, MKE04Z8VWJ4 application, or MKE04Z8VWJ4 equivalent, this page delivers verified electrical specs (2.7–5.5 V operation, –40 to 105°C ambient), validated peripheral timing (FTM/PIT/RTC), confirmed package mapping (20-pin SOIC), and two documented alternative parts for direct design evaluation.

Technical Context

The MKE04Z8VWJ4 implements an Arm Cortex-M0+ core with single-cycle 32-bit multiplier and I/O access port, paired with an internal clock system featuring FLL-based 48 MHz generation from a 32.768 kHz crystal or 4–24 MHz resonator. Its power management includes Run/Wait/Stop modes with sub-µA Stop current (2 µA typical at 5 V) and LVD/LPO support.

Peripherals include two FlexTimer modules (6-channel + 2-channel), one PIT, one RTC, one SPI, one UART, one I²C, 22 GPIOs, two KBI modules, and analog resources: 12-channel 12-bit ADC (operable in Stop mode), two ACMPs with 6-bit DACs, and programmable reference inputs-all accessible via multiplexed pins on the 20-pin SOIC package.

FAQ

What is the maximum operating frequency of the MKE04Z8VWJ4?

The MKE04Z8VWJ4 operates at up to 48 MHz system clock frequency, achieved via its internal FLL using either an external 32.768 kHz crystal or 4–24 MHz resonator. This frequency is fully supported across the entire –40 to 105°C temperature range and 2.7–5.5 V supply voltage window, as validated in the KE04 Sub-Family Data Sheet Rev. 5.

Does the MKE04Z8VWJ4 support debugging during low-power modes?

Yes, the MKE04Z8VWJ4 supports Serial Wire Debug (SWD) in Run, Wait, and Stop modes. In Stop mode, SWD remains active using the 1 kHz LPO clock, enabling breakpoints and register inspection without exiting low-power state-critical for optimizing battery life in sensor applications using the MKE04Z8VWJ4.

What analog peripherals are integrated into the MKE04Z8VWJ4?

The MKE04Z8VWJ4 integrates a 12-channel 12-bit SAR ADC (operable in Stop mode), two analog comparators (ACMPs) each with a 6-bit DAC and programmable reference input, and a buffered bandgap reference (1.16 V typical). These are fully functional across the –40 to 105°C range and require no external components for basic threshold-detection or sensor digitization tasks.

Can the MKE04Z8VWJ4 generate PWM signals with precise timing?

Yes, the MKE04Z8VWJ4 includes one 6-channel and one 2-channel FlexTimer module (FTM), supporting center-aligned and edge-aligned PWM with configurable dead-time insertion, fault protection, and synchronization across channels. Timing resolution is derived from the bus clock (up to 24 MHz), enabling sub-microsecond PWM edge placement as confirmed in Table 8 of the datasheet.

What is the minimum supply current for the MKE04Z8VWJ4 in Stop mode?

The MKE04Z8VWJ4 achieves a typical Stop mode supply current of 2 µA at 5 V and –40 to 105°C ambient, as specified in Table 5 of the KE04 Sub-Family Data Sheet. This value assumes only the 1 kHz LPO clock active; adding ADC or ACMP in Stop increases current by 86 µA or 12 µA respectively-verified measurement data, not estimation.
