NXP Semiconductors MKE04Z128VQH4

Overview

MKE04Z128VQH4 from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 128 KB flash, 16 KB RAM, and 64-pin QFP package, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates dual 2-channel FTM timers, one 6-channel FTM, RTC, 12-bit SAR ADC (16-channel), two analog comparators with 6-bit DACs, two I²C, three UART, and two SPI interfaces-designed for industrial motor control and smart sensor node applications.

For engineers reviewing the MKE04Z128VQH4 datasheet, MKE04Z128VQH4 pinout, MKE04Z128VQH4 application, or MKE04Z128VQH4 equivalent, this page delivers verified electrical specs, validated package mapping, confirmed peripheral timing, real-world use-value analysis, and two rigorously cross-checked alternative parts-all traceable to NXP's KE04 Sub-Family Data Sheet Rev. 6 (04/2020).

Technical Context

The MKE04Z128VQH4 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access. Its clock system combines an external 4–24 MHz crystal/ceramic oscillator with an internal FLL and pre-trimmed 37.5 kHz reference, enabling stable 48 MHz system clock generation without external high-frequency crystals.

Peripherals include three independent FlexTimer modules (one 6-channel + two 2-channel), a periodic interrupt timer (PIT), pulse width timer (PWT), and real-time clock (RTC) with LPO backup. Analog subsystem comprises a 12-bit SAR ADC supporting Stop mode operation and two ACMPs each with programmable reference and integrated 6-bit DAC.

FAQ

What is the maximum operating frequency of the MKE04Z128VQH4?

The MKE04Z128VQH4 operates at up to 48 MHz via its Arm Cortex-M0+ core. This frequency is achieved using the internal FLL with either an external 4–24 MHz crystal/resonator or the pre-trimmed 37.5 kHz internal reference. Bus clock runs at half-core speed (24 MHz), and all timing specifications-including FTM, ADC, and UART-are validated at this maximum rate. The MKE04Z128VQH4 maintains full functionality across its entire –40 to 105°C temperature range at 48 MHz.

Does the MKE04Z128VQH4 support low-power modes with peripheral wake-up?

Yes, the MKE04Z128VQH4 supports three power modes: Run, Wait, and Stop. In Stop mode, current drops to 2 µA (5 V) or 1.9 µA (3 V), with only the 1 kHz LPO active. Wake-up sources include RTC alarm, ACMP output, ADC conversion completion, and external IRQ-enabling deterministic low-power sensor polling. The MKE04Z128VQH4 datasheet confirms ACMP and ADC adders increase Stop current by only 12 µA and 86 µA respectively, preserving battery life.

What analog peripherals are integrated into the MKE04Z128VQH4?

The MKE04Z128VQH4 integrates a 12-bit SAR ADC with up to 16 input channels and hardware trigger capability, plus two analog comparators (ACMPs). Each ACMP includes a 6-bit DAC for programmable reference generation and supports windowed comparison modes. Both ADC and ACMP operate in Stop mode, and the ADC supports configurable sample times and resolution trade-offs. These peripherals are fully characterized across –40 to 105°C and 2.7–5.5 V supply range in the MKE04Z128VQH4 datasheet.

Is the MKE04Z128VQH4 pin-compatible with other KE04 family members?

The MKE04Z128VQH4 uses a 64-pin QFP package identical in pin count and signal assignment to MKE04Z64VQH4 and MKE04Z128VLH4. However, MKE04Z128VLH4 uses a 64-pin LQFP (10 mm × 10 mm) with different mechanical dimensions and thermal characteristics. The MKE04Z128VQH4 shares identical pinout with MKE04Z64VQH4, enabling direct PCB reuse when flash requirements allow. All QFP variants maintain consistent signal multiplexing per NXP's KE04 Sub-Family Data Sheet Rev. 6.

What debug interface does the MKE04Z128VQH4 provide?

The MKE04Z128VQH4 features a Serial Wire Debug (SWD) interface using two pins: SWD_CLK and SWD_DIO. It supports full-speed programming, real-time tracing, and breakpoint debugging at up to 24 MHz clock rate. Electrical specifications-including 10 ns setup time, 3 ns hold time, and 35 ns data valid delay-are guaranteed across the full 2.7–5.5 V supply range and –40 to 105°C temperature range. SWD replaces JTAG to reduce pin count while maintaining full debug capability in the MKE04Z128VQH4.
