NXP Semiconductors MKE12Z128VLL7

Overview

MKE12Z128VLL7 from NXP Semiconductors is an ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 128 KB flash, 32 KB SRAM, and 89 GPIOs in a 100-pin LQFP package. It integrates a 12-bit 1 Msps ADC, three FlexTimers for PWM motor control, and low-power peripherals including LPUART, LPSPI, and LPI2C - deployed in BLDC motor drives and industrial HMI systems.

For engineers reviewing the MKE12Z128VLL7 datasheet, MKE12Z128VLL7 pinout, MKE12Z128VLL7 application, or MKE12Z128VLL7 equivalent, key selection criteria include its 72 MHz Cortex-M0+ core, 100-pin LQFP thermal profile (–40 to 105 °C), integrated TSI touch sensing support, and verified low-power operation across VLPR/VLPS/Stop modes with wake-up via ADC, CMP, or LPUART.

Technical Context

The MKE12Z128VLL7 implements a dual-clock domain architecture: a high-speed bus clock (up to 24 MHz) for peripherals and a 72 MHz core clock derived from FIRC, SIRC, or external OSC. Its SCG module enables dynamic clock source switching between 48 MHz FIRC (±1%), 8/2 MHz SIRC (±3%), and 32 kHz LPO, with LPFLL for fine frequency tuning.

Power management is handled by PMC with six operational modes (Run, Wait, Stop, VLPR, VLPW, VLPS); critical peripherals like ADC, CMP, LPTMR, and LPUART retain functionality in VLPS mode using SIRC or OSC clocks. The AWIC controller provides asynchronous wake-up from Stop/VLPS using pin interrupts, ADC conversion completion, or LPUART start-bit detection.

FAQ

What is the maximum operating frequency of the MKE12Z128VLL7 core?

The MKE12Z128VLL7 features an ARM Cortex-M0+ core rated for up to 72 MHz operation. This frequency is achievable using the 48 MHz Fast Internal Reference Clock (FIRC) with PLL multiplication or directly from an external crystal oscillator. Electrical specifications guarantee timing closure across the full –40 to 105 °C range at this speed when supplied with 2.7–5.5 V.

Does the MKE12Z128VLL7 support capacitive touch sensing?

No, the MKE12Z128VLL7 does not include integrated Touch Sensing Input (TSI) modules. Unlike MKE13Z/MKE17Z variants, the KE12Z series omits TSI hardware - confirmed in the device's functional block diagram and ordering table. For touch-enabled designs, engineers must select MKE13Z128VLL7 or MKE17Z128VLL7, which provide 25- or 50-channel TSI respectively.

What low-power modes are supported by the MKE12Z128VLL7?

The MKE12Z128VLL7 supports six low-power modes managed by the Power Management Controller (PMC): Run, Wait, Stop, Very Low Power Run (VLPR), Very Low Power Wait (VLPW), and Very Low Power Stop (VLPS). In VLPS mode, the device draws <1.5 μA while retaining SRAM content and enabling wake-up via LPUART, ADC, CMP, or LPTMR - verified per NXP datasheet Rev. 2.2 Section 2.1.8.

How many UART interfaces does the MKE12Z128VLL7 include?

The MKE12Z128VLL7 integrates three independent Low-Power UART (LPUART) modules. Each supports programmable baud rates with 4×–32× oversampling, DMA transfers, and operation in Stop/VLPS modes using SIRC or OSC clocks - enabling concurrent diagnostics, sensor telemetry, and firmware update channels without CPU intervention.

Is the MKE12Z128VLL7 pin-compatible with other KE1xZ family members?

Yes, the MKE12Z128VLL7 in 100-pin LQFP (VLL7) shares identical pinout and footprint with MKE13Z128VLL7 and MKE17Z128VLL7. All three devices use the same 100-LQFP mechanical outline (98ASS23308W), allowing drop-in replacement in PCB layouts - though functional differences (e.g., TSI presence, SRAM size) require firmware validation before substitution.
