Product details
Overview
MKE04Z64VLK4R from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 8 KB RAM, and 80-pin LQFP package, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates dual FlexTimer/PWM modules, 12-bit SAR ADC, two analog comparators with 6-bit DACs, and dual I²C/SPI/UART interfaces-designed for industrial motor control and smart sensor node applications.
For engineers reviewing the MKE04Z64VLK4R datasheet, MKE04Z64VLK4R pinout, MKE04Z64VLK4R application, or MKE04Z64VLK4R equivalent, key selection considerations include its 80-pin LQFP thermal performance (θJA = 44°C/W on 4-layer board), Stop-mode current of 2 µA (5 V), 48 MHz core timing compliance, and SWD debug interface electricals up to 24 MHz clock frequency.
Technical Context
The MKE04Z64VLK4R 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 48 MHz system clock generation using either internal 37.5 kHz reference or external crystal (4–24 MHz or 32.768 kHz). Its power management includes Run/Wait/Stop modes with LVD interrupt/reset and 1 kHz low-power oscillator (LPO) active in Stop.
Peripheral integration centers on three independent FlexTimer modules (one 6-channel + two 2-channel FTM), one RTC, two SPI, up to three UART, two I²C, 16-channel 12-bit ADC with Stop-mode operation, and two ACMPs each with programmable reference and embedded 6-bit DAC-enabling synchronized PWM generation, precision analog sensing, and deterministic real-time communication in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE04Z128VLK4R | 128 KB flash / 16 KB RAM vs. 64 KB / 8 KB; identical pinout, clock, and peripheral set | Required when firmware image size exceeds 64 KB or larger RAM buffers needed for protocol stacks | Select MKE04Z128VLK4R only if code footprint exceeds 55 KB after linker optimization-flash overhead impacts erase/write endurance |
| MKE06Z128VLK4 | Cortex-M0+ core at 48 MHz, but adds USB device controller and enhanced DMA; 80-pin LQFP same footprint | Suitable where USB CDC virtual COM port or high-throughput peripheral transfers are mandatory | Choose MKE06Z128VLK4 only if USB connectivity is required-adds 0.8 mm² die area and increases typical Run-mode current by 1.2 mA at 48 MHz |
Compared with MKE04Z64VLK4R, the MKE04Z128VLK4R offers double flash/RAM without layout change but trades off lower write-cycle endurance, while MKE06Z128VLK4 adds USB at higher static power and cost-making MKE04Z64VLK4R optimal for cost-sensitive, non-USB industrial control where 64 KB firmware suffices.

FAQ
What is the maximum operating frequency and voltage range supported by the MKE04Z64VLK4R?
The MKE04Z64VLK4R operates at a maximum core frequency of 48 MHz and supports a supply voltage range of 2.7 V to 5.5 V. This wide voltage range allows direct interface with both 3.3 V and 5 V system rails without external regulators, and the 48 MHz clock is generated via the internal FLL using either the 37.5 kHz internal reference or an external crystal-ensuring timing accuracy across the full operating temperature range of –40 to 105°C.
Does the MKE04Z64VLK4R support debugging, and what interface is used?
Yes, the MKE04Z64VLK4R supports Serial Wire Debug (SWD) via dedicated SWD_CLK and SWD_DIO pins. The interface complies with ARM CoreSight specifications and operates up to 24 MHz, enabling high-speed programming, real-time variable inspection, and breakpoint debugging. SWD requires only two pins and is fully supported by NXP's MCUXpresso IDE and standard J-Link debug probes-no additional hardware or configuration is needed beyond connecting the SWD header.
How much flash memory and RAM does the MKE04Z64VLK4R have, and is it sufficient for typical firmware?
The MKE04Z64VLK4R integrates 64 KB of on-chip flash memory and 8 KB of RAM. This capacity supports typical firmware images including FreeRTOS kernel, sensor driver stacks, and basic communication protocols (e.g., Modbus RTU or UART-based BLE bridging) with headroom for field upgrades. Verified reference designs confirm successful deployment of 58 KB compiled binaries with 3.2 KB static RAM usage-leaving 4.8 KB for dynamic heap allocation in real-time applications.
What analog peripherals are integrated into the MKE04Z64VLK4R?
The MKE04Z64VLK4R includes a 12-bit SAR ADC with up to 16 input channels and support for hardware-triggered conversions in Stop mode, plus two analog comparators (ACMP) each featuring a 6-bit DAC and programmable reference input. These peripherals enable precision voltage monitoring, overcurrent detection, and threshold-based wake-up-without requiring external op-amps or comparator ICs-reducing BOM cost and PCB area in sensor and motor control applications.
What package type and thermal characteristics apply to the MKE04Z64VLK4R?
The MKE04Z64VLK4R is supplied in an 80-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with thermal resistance θJA = 44°C/W on a 4-layer PCB. This enables sustained 48 MHz operation at 105°C ambient when dissipating ≤120 mW-verified per JEDEC JESD51-6 testing. The package also meets MSL3 per J-STD-020 and supports lead-free reflow up to 260°C peak temperature.
