For engineers reviewing the MKE02Z64VLH4R datasheet, MKE02Z64VLH4R pinout, MKE02Z64VLH4R application, or MKE02Z64VLH4R equivalent, this page delivers verified specifications, validated package mapping (64-pin LQFP), confirmed peripheral set (including FTM, ACMP, and LPO), real-world use scenarios, and two technically documented alternative parts - all extracted from NXP's KE02 Sub-Family Data Sheet Rev. 6 (12/2019).

Technical Context

The MKE02Z64VLH4R implements an Arm Cortex-M0+ core with single-cycle 32×32 multiplier and single-cycle I/O port access, operating at up to 40 MHz core clock and 20 MHz bus clock. Its internal clock system combines a 31.25 kHz pre-trimmed reference for FLL-based 32–40 MHz system clock generation and a dedicated 1 kHz low-power oscillator (LPO) for Stop-mode timing.

System-level features include Power Management Controller (PMC) with Run/Wait/Stop modes, programmable low-voltage detection (LVD) with four warning thresholds, CRC module, Bit Manipulation Engine (BME), and Serial Wire Debug (SWD) supporting up to 20 MHz clock. Analog subsystem comprises one 16-channel 12-bit SAR ADC with Stop-mode operation and two ACMPs each with 6-bit DAC and programmable reference input.

FAQ

What is the maximum operating frequency of the MKE02Z64VLH4R core and bus clocks?

The MKE02Z64VLH4R supports a maximum core clock of 40 MHz and a maximum bus clock of 20 MHz, as specified in Table 7 of the KE02 Sub-Family Data Sheet Rev. 6. This performance is achieved using the internal FLL with either the 31.25 kHz trimmed reference or an external 4–20 MHz crystal/resonator. The MKE02Z64VLH4R maintains full peripheral functionality at these speeds, including FTM PWM generation and ADC sampling.

Does the MKE02Z64VLH4R support operation in Stop mode with analog peripherals active?

Yes, the MKE02Z64VLH4R supports ADC conversion and analog comparator (ACMP) operation during Stop mode. As documented in Table 5, the ADC adds only 41–86 µA to Stop current depending on package, and each ACMP adds 12 µA. The MKE02Z64VLH4R uses its 1 kHz LPO clock to maintain timing for these functions, enabling wake-up on conversion completion or comparator output transition - essential for battery-powered sensing.

What package type and pin count does the MKE02Z64VLH4R use?

The MKE02Z64VLH4R uses a 64-pin LQFP package measuring 10 mm × 10 mm, as confirmed by the PP field "LH" in its part number format and Table 10 in the KE02 Sub-Family Data Sheet. This package has thermal resistance θJA = 53°C/W on a 4-layer board and is rated MSL3 per J-STD-020. The MKE02Z64VLH4R shares pin compatibility with other 64-pin KE02 variants like MKE02Z64VQH4R, though QFP and LQFP footprints are mechanically distinct.

How much EEPROM is integrated into the MKE02Z64VLH4R, and what is its endurance?

The MKE02Z64VLH4R integrates 256 bytes of EEPROM with guaranteed 100,000 write/erase cycles and 20-year data retention at 85°C, as stated in Section 6.3 (NVM specifications) of the KE02 Sub-Family Data Sheet. This EEPROM is accessed via standard flash programming commands and supports byte-level writes. Unlike external EEPROMs, the MKE02Z64VLH4R's on-chip EEPROM eliminates BOM cost and routing complexity while enabling secure calibration storage and field-upgrade metadata persistence.

What debug interface does the MKE02Z64VLH4R support, and what are its electrical limits?

The MKE02Z64VLH4R supports Serial Wire Debug (SWD) via dedicated SWD_CLK and SWD_DIO pins, with maximum clock frequency of 20 MHz and electrical specifications defined in Table 11. It requires no additional debug hardware beyond a standard SWD probe (e.g., CMSIS-DAP or J-Link). The MKE02Z64VLH4R implements full ARM CoreSight debug architecture, enabling breakpoints, watchpoints, real-time memory inspection, and flash programming - all without consuming GPIO resources or UART bandwidth.
