NXP Semiconductors MKE15Z128VLH7R

Overview

MKE15Z128VLH7R from NXP Semiconductors is an ARM® Cortex®-M0+ microcontroller delivering up to 72 MHz operation, 128 KB flash, 16 KB SRAM, and integrated 12-bit ADCs with 1 Msps sampling rate. It features 58 GPIOs (8 high-drive), touch-sensing input (TSI) with 25 channels, and dual LPUART/LPSPI/LPI2C interfaces - optimized for BLDC motor control and industrial HMI systems.

For engineers reviewing the MKE15Z128VLH7R datasheet, MKE15Z128VLH7R pinout, MKE15Z128VLH7R application, or MKE15Z128VLH7R equivalent, key selection criteria include its 64-pin LQFP package, 2.7–5.5 V operating range, –40 to 105 °C temperature grade, FlexNVM-based EEPROM emulation, and low-power stop-mode wake-up via CMP/ADC/LPTMR/RTC.

Technical Context

The MKE15Z128VLH7R implements a single-core ARM Cortex-M0+ executing Thumb®-2 instructions at up to 72 MHz, with memory-mapped divide/square-root (MMDVSQ) and configurable NVIC supporting 32 interrupt vectors. Its clock system integrates FIRC (48–60 MHz ±1%), SIRC (2/8 MHz ±3%), OSC32, LPO, and LPFLL - all managed by SCG with dynamic clock gating.

Peripheral subsystems include three FlexTimers (FTM) with dead-time insertion and fault inputs for motor control, two 12-bit SAR ADCs (16+11 analog inputs total), two comparators with integrated 8-bit DACs, and a TSI module supporting robust capacitive touch sensing. All operate in VLPS/Stop modes using SIRC or OSC32 clocks.

FAQ

What is the maximum operating frequency of the MKE15Z128VLH7R?

The MKE15Z128VLH7R operates at up to 72 MHz using the Fast Internal Reference Clock (FIRC) or external crystal. This frequency is sustained across its full –40 to 105 °C temperature range and 2.7–5.5 V supply, enabling deterministic execution of motor control loops with cycle times under 140 ns per instruction.

Does the MKE15Z128VLH7R support EEPROM emulation?

Yes, the MKE15Z128VLH7R includes 32 KB of FlexNVM configured as data flash and 2 KB of FlexRAM for EEPROM emulation. This allows byte-level read/write operations with built-in wear leveling and atomic update support - essential for storing calibration data, device configuration, and fault logs without external memory.

Can the MKE15Z128VLH7R wake from VLPS mode using analog peripherals?

Yes, the MKE15Z128VLH7R supports wake-up from VLPS mode via its ADC, comparators (CMP), LPTMR, RTC, and TSI modules - all functional with SIRC or OSC32 clocks. This enables ultra-low-power sensor polling (e.g., temperature or touch) with wake latency under 3 µs and total sleep current below 5 µA.

What debug interface does the MKE15Z128VLH7R use?

The MKE15Z128VLH7R uses Serial Wire Debug (SWD) as its primary debug interface, compliant with ARM CoreSight standards. It supports full run-control, breakpoint setting, memory inspection, and Micro Trace Buffer (MTB) for instruction trace - all accessible through standard tools like MCUXpresso IDE and J-Link debug probes.

Is the MKE15Z128VLH7R qualified for automotive applications?

The MKE15Z128VLH7R is rated for –40 to 105 °C operation and meets AEC-Q100 stress test requirements for Grade 2 temperature range. While not officially AEC-Q100 certified out-of-box, its electrical specs, packaging, and qualification testing align with automotive accessory applications such as seat controls, HVAC actuators, and body electronics.
