NXP Semiconductors MKE04Z128VLH4R

Overview

MKE04Z128VLH4R from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 128 KB flash, 16 KB RAM, and operation across –40 to 105°C ambient. It integrates dual FlexTimer/PWM modules, 12-bit SAR ADC with Stop-mode operation, two analog comparators with 6-bit DACs, and supports UART, SPI, and I²C interfaces for industrial sensor node and motor control applications.

For engineers reviewing the MKE04Z128VLH4R datasheet, MKE04Z128VLH4R pinout, MKE04Z128VLH4R application, or MKE04Z128VLH4R equivalent, key selection considerations include its 64-pin LQFP package, 2.7–5.5 V supply range, low-power Stop mode (2 µA), SWD debug interface, and compatibility with KE04 sub-family toolchains and SDKs.

Technical Context

The MKE04Z128VLH4R implements an Arm Cortex-M0+ core with single-cycle 32×32 multiplier and single-cycle I/O port access. Its clock system combines an external 4–24 MHz crystal oscillator with an internal FLL and pre-trimmed 37.5 kHz reference, enabling precise 48 MHz system clock generation without external high-frequency crystals.

Peripherals include three independent FlexTimer modules (one 6-channel + two 2-channel), RTC with 1 kHz LPO source, programmable CRC engine, and Bit Manipulation Engine (BME) for atomic bit-field operations - all operating under PMC-managed Run/Wait/Stop power modes with configurable LVD thresholds and WDOG reset capability.

FAQ

What is the maximum operating frequency of the MKE04Z128VLH4R?

The MKE04Z128VLH4R operates at up to 48 MHz using its Arm Cortex-M0+ core. This frequency is achieved via the internal FLL locked to either an external 4–24 MHz crystal or the factory-trimmed 37.5 kHz internal reference. The bus clock runs at half the core frequency (24 MHz), and all timing-critical peripherals - including FTM, ADC, and UART - are fully specified at this rate. MKE04Z128VLH4R maintains timing compliance across its full –40 to 105°C temperature and 2.7–5.5 V supply range.

Does the MKE04Z128VLH4R support debugging via SWD?

Yes, the MKE04Z128VLH4R includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. It uses two dedicated pins - SWD_CLK and SWD_DIO - and supports full-speed debugging, flash programming, and real-time trace at up to 24 MHz clock rate. No external reset pin is required for SWD initialization, and the interface remains functional across all power modes except deep Stop. MKE04Z128VLH4R debug configuration is handled entirely through the SWD protocol without requiring additional hardware signals.

What analog peripherals are integrated into the MKE04Z128VLH4R?

The MKE04Z128VLH4R integrates one 12-bit SAR ADC with up to 16 input channels and two analog comparators (ACMP). Each ACMP includes an internal 6-bit DAC for programmable reference voltage generation and supports hysteresis configuration. The ADC supports hardware triggering, continuous conversion, and operation in Stop mode - enabling ultra-low-power periodic sensing. All analog blocks share the same VDDA/VSSA supply domain and are characterized across –40 to 105°C. MKE04Z128VLH4R does not include DACs beyond those embedded in the ACMP modules.

What power modes does the MKE04Z128VLH4R support, and what is its lowest current consumption?

The MKE04Z128VLH4R supports Run, Wait, and Stop power modes managed by the Power Management Controller (PMC). In Stop mode with only the 1 kHz LPO active, typical current consumption is 2 µA at 5 V and –40 to 105°C. With ADC enabled in Stop, consumption rises to 86 µA; with ACMP active, it is 12 µA. The LVD module adds 130 µA when periodically enabled. These values are measured under specified conditions and documented in Table 5 of the KE04 Sub-Family Data Sheet. MKE04Z128VLH4R achieves these figures without external circuitry or special biasing.

Is the MKE04Z128VLH4R pin-compatible with other KE04 family members?

The MKE04Z128VLH4R is pin-compatible with other 64-pin LQFP KE04 variants sharing the VLH4 suffix - specifically MKE04Z64VLH4R and MKE04Z128VLH4 (non-R tape-and-reel version). Pin assignments for VDD, VSS, XTAL, SWD, GPIO, and peripheral functions match exactly across these parts. However, it is not pin-compatible with 44-pin (VLD4) or 80-pin (VLK4) variants due to differing pin counts and signal mappings. MKE04Z128VLH4R software is binary-compatible across the KE04Z sub-family when flash/RAM size differences are accounted for in linker configuration.
