NXP Semiconductors MKE04Z64VLH4R

Overview

MKE04Z64VLH4R from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 8 KB RAM, and 64-pin LQFP package, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates dual 2-channel FTM timers, 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 MKE04Z64VLH4R datasheet, MKE04Z64VLH4R pinout, MKE04Z64VLH4R application, or MKE04Z64VLH4R equivalent, key selection considerations include its 64-pin LQFP footprint, 48 MHz real-time performance with low-power Stop mode (2 µA), integrated analog peripherals, and SWD debug support-critical for cost-sensitive embedded control designs requiring extended temperature operation and mixed-signal integration.

Technical Context

The MKE04Z64VLH4R implements an Arm Cortex-M0+ core with single-cycle 32×32 multiplier and single-cycle I/O port access, paired with an internal clock system (ICS) featuring FLL-based 48 MHz system clock generation from 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 Stop mode retaining RTC and LPO while drawing only 2 µA at 5 V.

Peripherals are tightly coupled to the bus architecture: the 12-bit SAR ADC supports hardware-triggered conversions in Stop mode; two ACMP modules each integrate a 6-bit DAC and programmable reference input; and timer resources include one 6-channel FTM, two 2-channel FTM modules, PIT, PWT, and RTC-all synchronized to the same bus clock domain for deterministic timing control.

FAQ

What is the maximum operating frequency of the MKE04Z64VLH4R?

The MKE04Z64VLH4R operates at a maximum system clock frequency of 48 MHz, achieved via its internal FLL using either the 37.5 kHz internal reference or an external crystal (4–24 MHz). This frequency is fully supported across the full –40 to 105°C temperature range and 2.7–5.5 V supply voltage, enabling deterministic real-time control in demanding industrial environments. The MKE04Z64VLH4R maintains timing compliance under all specified operating conditions without derating.

Does the MKE04Z64VLH4R support debugging during low-power modes?

Yes, the MKE04Z64VLH4R supports Serial Wire Debug (SWD) in Run and Wait modes, allowing full visibility into registers and memory during active execution. However, SWD is disabled in Stop mode to minimize leakage current-debugging requires wake-up to Run mode first. The MKE04Z64VLH4R retains SWD functionality across all voltage and temperature ranges, and its SWD_CLK supports up to 24 MHz for high-speed programming and trace. This behavior is consistent across all KE04Z variants including the MKE04Z64VLH4R.

How much current does the MKE04Z64VLH4R draw in Stop mode?

The MKE04Z64VLH4R draws 2 µA typical supply current in Stop mode at 5 V and 25°C, with a maximum of 105 µA across the full –40 to 105°C range. This includes the 1 kHz LPO oscillator running continuously. Additional peripherals like the ADC or ACMP can be enabled in Stop mode, adding 86 µA (ADC), 12 µA (ACMP), or 130 µA (LVD) respectively. These values are measured and guaranteed per the MKE04P80M48SF0 datasheet Rev. 6, confirming the MKE04Z64VLH4R's suitability for ultra-low-power battery applications.

What analog peripherals are integrated into the MKE04Z64VLH4R?

The MKE04Z64VLH4R integrates a 12-bit SAR ADC with up to 16 input channels, capable of operation in Stop mode with hardware triggering; two analog comparators (ACMP0 and ACMP1), each with a 6-bit DAC and programmable reference input; and a buffered bandgap reference (1.16 V typical) for precision analog measurements. These peripherals are fully specified in the MKE04P80M48SF0 datasheet and are shared across the KE04Z subfamily, including the MKE04Z64VLH4R. No external components are required for basic comparator thresholding or ADC reference stability.

Is the MKE04Z64VLH4R pin-compatible with other KE04Z variants?

No, the MKE04Z64VLH4R is not pin-compatible with other KE04Z variants due to differing package footprints: MKE04Z64VLH4R uses a 64-pin LQFP, while MKE04Z64VLD4 uses 44-pin LQFP and MKE04Z64VQH4R uses 64-pin QFP. Although all share identical peripheral register maps and software compatibility, mechanical layout changes are required when substituting between these packages. The MKE04Z64VLH4R's 64-pin LQFP (10 mm × 10 mm) is distinct from both VLD and VQH variants, and pin assignments differ accordingly per the official NXP pinout documentation.
