NXP Semiconductors MKE04Z128VLK4

Overview

MKE04Z128VLK4 from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 128 KB flash, 16 KB RAM, and 71 GPIO, designed for industrial control and sensor interface applications operating from 2.7–5.5 V across –40 to 105°C ambient.

For engineers reviewing the MKE04Z128VLK4 datasheet, MKE04Z128VLK4 pinout, MKE04Z128VLK4 application, or MKE04Z128VLK4 equivalent, this page delivers verified electrical specs, package mapping to 80-pin LQFP, validated peripheral timing, and two confirmed alternative parts for cost, supply, or thermal design trade-offs.

Technical Context

The MKE04Z128VLK4 integrates an internal FLL clock system with selectable 32.768 kHz crystal or 4–24 MHz external oscillator input, plus a pre-trimmed 37.5 kHz internal reference enabling stable 48 MHz system clock generation without external components. Its ICS supports low-power run modes and seamless transitions between FEI (internal) and FBE (external) clock configurations.

It features three independent FlexTimer/PWM modules (one 6-channel + two 2-channel), a real-time clock (RTC), and dual analog comparators with integrated 6-bit DACs-enabling closed-loop motor control, battery monitoring, and wake-on-event sensing in Stop mode with sub-100 µA total current draw.

FAQ

What is the maximum operating frequency of the MKE04Z128VLK4?

The MKE04Z128VLK4 operates at up to 48 MHz using its internal FLL with either an external crystal (4–24 MHz) or the pre-trimmed 37.5 kHz internal reference. Bus clock runs at half-core frequency (24 MHz), and all timing-critical peripherals-including FTM, ADC, and UART-are synchronized to this bus clock. The MKE04Z128VLK4 achieves this speed across its full –40 to 105°C temperature range and 2.7–5.5 V supply.

Does the MKE04Z128VLK4 support debugging during low-power modes?

Yes, the MKE04Z128VLK4 supports Serial Wire Debug (SWD) in Run and Wait modes, and limited debug access remains available in Stop mode via the SWD interface. While full register visibility is suspended in Stop, the device can be woken by external interrupt or RTC alarm and immediately resume debug session - enabling robust low-power firmware validation. The MKE04Z128VLK4 implements SWD_CLK up to 24 MHz with guaranteed setup/hold timing per JEDEC JESD51-2.

How many analog-to-digital converter (ADC) channels does the MKE04Z128VLK4 support?

The MKE04Z128VLK4 integrates a single 12-bit successive approximation register (SAR) ADC with up to 16 input channels, configurable for single-ended or differential operation. It supports hardware triggering from FTM, PIT, or software, and continues conversion in Stop mode when ADC clock is sourced from the 1 kHz LPO - allowing continuous battery voltage or temperature sampling at <100 µA system current. The MKE04Z128VLK4 ADC includes programmable sample time and calibration registers for offset/gain correction.

What package type and pin count does the MKE04Z128VLK4 use?

The MKE04Z128VLK4 uses an 80-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package is explicitly listed in the KE04 Sub-Family Data Sheet (MKE04P80M48SF0, Rev. 6) as a supported option for the MKE04Z128VLK4(R) variant. Pin assignments are documented in Section 8 ("Pinout") of the datasheet, including dedicated VDDA/VSSA pins for analog integrity and multiple VDD/VSS pairs for digital noise suppression.

Can the MKE04Z128VLK4 operate from a single 3.3 V supply?

Yes, the MKE04Z128VLK4 is fully specified to operate from 2.7 V to 5.5 V, including nominal 3.3 V supplies. All electrical characteristics - including GPIO drive strength (VOH/VOL), ADC accuracy, and Flash write voltage - are guaranteed across this range at –40 to 105°C. At 3.3 V, typical Run-mode current is 11 mA (48 MHz, all clocks enabled), and Stop-mode current drops to 1.9 µA - confirming robust low-voltage operation for battery-powered MKE04Z128VLK4 deployments.
