NXP Semiconductors MKE02Z64VLD4

Overview

MKE02Z64VLD4 from NXP Semiconductors is a 40 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 4 KB RAM, and 256 B EEPROM, operating across –40 to 105°C. It integrates a 12-bit SAR ADC (16-channel), dual analog comparators with 6-bit DACs, three UARTs, two SPIs, one I²C, six FTM/PWM channels, RTC, and SWD debug - deployed in industrial motor control, smart sensor nodes, and battery-powered HMI systems.

For engineers reviewing the MKE02Z64VLD4 datasheet, MKE02Z64VLD4 pinout, MKE02Z64VLD4 application, or MKE02Z64VLD4 equivalent, key selection criteria include its 44-pin LQFP package, 2.7–5.5 V supply range, Stop-mode current as low as 2 µA, 40 MHz core clock capability, and integrated low-voltage detection with programmable trip points.

Technical Context

The MKE02Z64VLD4 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiply and single-cycle I/O port access. Its clock system combines an internal FLL (tuned from 31.25 kHz reference to up to 40 MHz) and external crystal support (32.768 kHz or 4–20 MHz), enabling precise timing for real-time control loops and low-power wake-up events.

System-level integration includes Power Management Module (PMC) supporting Run/Wait/Stop modes, programmable cyclic redundancy check (CRC), bit manipulation engine (BME), and serial wire debug (SWD) with 20 MHz clock tolerance. Analog subsystem features ADC operation in Stop mode with hardware trigger, and ACMP modules with internal reference selection - critical for deterministic sensor acquisition in energy-constrained applications.

FAQ

What is the maximum operating frequency of the MKE02Z64VLD4 core and bus clock?

The MKE02Z64VLD4 features an Arm Cortex-M0+ core rated for up to 40 MHz operation, with a corresponding maximum bus clock of 20 MHz. This frequency is achieved using the internal FLL tuned from the 31.25 kHz internal reference or an external crystal. The MKE02Z64VLD4 datasheet specifies these values under DC to 40 MHz for fSys and DC to 20 MHz for fBus in Table 7, Control Timing.

Does the MKE02Z64VLD4 support analog-to-digital conversion in low-power Stop mode?

Yes, the MKE02Z64VLD4 supports 12-bit SAR ADC operation in Stop mode when configured with ADLPC = 1, ADLSMP = 1, ADCO = 1, MODE = 10B, and ADICLK = 11B. In this configuration, typical Stop-mode current increases by only 42–86 µA depending on package size, enabling precise sensor sampling without exiting low-power state - a key feature confirmed in Table 5 of the KE02 Sub-Family Data Sheet Rev. 6.

What package type and pin count does the MKE02Z64VLD4 use?

The MKE02Z64VLD4 uses a 44-pin LQFP package (10 mm × 10 mm, 0.8 mm pitch), identified by the "LD" suffix in its part number per NXP's KE02 naming convention. This is explicitly listed in Section 2.3 (Fields) of the KE02 Sub-Family Data Sheet Rev. 6, where "PP = LD" maps to "44 LQFP (10 mm x 10 mm)".

Can the MKE02Z64VLD4 operate across the full industrial temperature range?

Yes, the MKE02Z64VLD4 is specified for ambient temperatures from –40°C to +105°C, as indicated by the "V" in its part number (MKE02Z64VLD4) and confirmed in Section 4.4 (Voltage and current operating ratings) and Table 9 (Thermal operating requirements) of the KE02 Sub-Family Data Sheet Rev. 6.

What debug interface does the MKE02Z64VLD4 provide, and what are its electrical limits?

The MKE02Z64VLD4 provides Serial Wire Debug (SWD) via dedicated SWD_CLK and SWD_DIO pins. Per Table 11 in the KE02 Sub-Family Data Sheet Rev. 6, SWD_CLK operates up to 20 MHz, with input setup time ≥10 ns, hold time ≥3 ns, and rise/fall times ≤3 ns - enabling high-speed programming and real-time debugging across the full 2.7–5.5 V supply range.
