Product details
Overview
MKE04Z64VQH4 from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 8 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 FlexTimer/PWM modules, one 6-channel FlexTimer/PWM, 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 MKE04Z64VQH4 datasheet, MKE04Z64VQH4 pinout, MKE04Z64VQH4 application, or MKE04Z64VQH4 equivalent, key selection criteria include its 64-pin QFP footprint, 48 MHz real-time performance, low-power Stop mode (2 µA @ 5 V), integrated analog peripherals, and SWD debug interface compatibility with standard ARM toolchains.
Technical Context
The MKE04Z64VQH4 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access, paired with an Internal Clock Source (ICS) featuring FLL-based frequency synthesis and a pre-trimmed 37.5 kHz internal reference for stable 48 MHz system clock generation. Its clock architecture supports external 32.768 kHz crystals or 4–24 MHz resonators via configurable low-power/high-gain oscillator modes.
System-level timing is managed by a programmable periodic interrupt timer (PIT), pulse width timer (PWT), real-time clock (RTC), and three independent FlexTimer modules supporting edge-aligned PWM, input capture, and quadrature decoding. Analog subsystem includes hardware-triggered ADC operation in Stop mode and ACMPs with selectable reference inputs and built-in 6-bit DACs for comparator offset calibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE04Z128VQH4 | 128 KB flash / 16 KB RAM, same package and peripheral set | Required when application firmware exceeds 64 KB or demands larger data buffers for communication stacks | Select MKE04Z128VQH4 only if code size analysis confirms >64 KB usage; identical pinout and software compatibility simplify migration |
| Kinetis KE02Z64VQH4 | Same core, flash/RAM, and package but lacks RTC and one FTM module; lower qualification grade | Suitable for cost-sensitive consumer products where RTC and advanced timer features are unnecessary | Choose KE02Z64VQH4 only for non-automotive/non-industrial use cases; verify absence of RTC does not impact system timekeeping requirements |
Compared with MKE04Z64VQH4, the MKE04Z128VQH4 offers double flash/RAM with zero hardware changes, while the KE02Z64VQH4 reduces feature set and qualification rigor-making both viable alternatives only when specific memory or functional constraints align with their documented capabilities.
