NXP Semiconductors MKE02Z64VLC4

Overview

MKE02Z64VLC4 from NXP Semiconductors is a 40 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 4 KB RAM, and 256 B EEPROM, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates a 12-bit SAR ADC, dual analog comparators with 6-bit DACs, three UARTs, two SPIs, one I²C, six FTM timer channels, RTC, and SWD debug-targeting industrial sensor nodes and low-power motor control.

For engineers reviewing the MKE02Z64VLC4 datasheet, MKE02Z64VLC4 pinout, MKE02Z64VLC4 application, or MKE02Z64VLC4 equivalent, key selection criteria include its 32-pin LQFP (7 mm × 7 mm) package, 57 GPIOs with keyboard interrupt support, stop-mode current as low as 1.9 µA at 3 V, and compatibility with KE02Z family toolchains and NXP MCUXpresso SDK.

Technical Context

The MKE02Z64VLC4 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiply and single-cycle I/O port access, paired with an Internal Clock Source (ICS) featuring a trimmable FLL for up to 40 MHz system clock generation. Its clock system supports external 32.768 kHz crystals or 4–20 MHz resonators alongside a 1 kHz low-power oscillator (LPO) for RTC and stop-mode wake-up.

System-level peripherals include a Power Management Controller (PMC) supporting Run/Wait/Stop modes, programmable Low-Voltage Detect (LVD) with four warning thresholds, and a Bit Manipulation Engine (BME) for atomic bit-field operations. Analog subsystems feature ADC conversion in Stop mode with hardware trigger capability and ACMP modules with internal reference selection and DAC-based hysteresis control.

FAQ

What is the maximum system clock frequency supported by the MKE02Z64VLC4?

The MKE02Z64VLC4 supports a maximum system clock frequency of 40 MHz, achieved via its Internal Clock Source (ICS) with a trimmable FLL using either internal or external reference. This 40 MHz core clock enables deterministic real-time execution for motor control and sensor processing tasks. The MKE02Z64VLC4 achieves this rating across its full –40 to 105°C operating range and 2.7–5.5 V supply voltage window.

Does the MKE02Z64VLC4 support ADC conversions while in Stop mode?

Yes, the MKE02Z64VLC4 supports ADC conversions during Stop mode, with typical added current of 41–42 µA (depending on package) when ADC is active. This capability allows battery-powered systems to perform periodic sensor measurements without exiting low-power state. The MKE02Z64VLC4 also supports hardware triggering of ADC conversions via RTC or ACMP events, enabling fully autonomous wake-up and sampling sequences.

What debug interface does the MKE02Z64VLC4 use, and what are its electrical limits?

The MKE02Z64VLC4 uses Serial Wire Debug (SWD) with dedicated SWD_CLK and SWD_DIO pins. It operates across the full 2.7–5.5 V supply range and supports up to 20 MHz clock frequency. Minimum setup/hold times are 10 ns and 3 ns respectively, with rise/fall times limited to 3 ns. This interface enables full-speed programming, real-time tracing, and non-intrusive breakpoints without requiring dedicated JTAG pins-reducing PCB routing complexity for the MKE02Z64VLC4.

How many general-purpose I/O pins does the MKE02Z64VLC4 provide, and what advanced functions do they support?

The MKE02Z64VLC4 provides up to 57 general-purpose I/O pins across its 32-pin LQFP package, all configurable as digital inputs/outputs with programmable pullup/pulldown resistors. These pins support advanced functions including UART, SPI, I²C, FTM PWM outputs, ADC inputs, keyboard interrupt (KBI), and external IRQ. Eight pins (PTB4, PTB5, PTD0, PTD1, PTE0, PTE1, PTH0, PTH1) offer high-drive strength (20 mA sink/source), making them suitable for direct LED driving or relay coil control in the MKE02Z64VLC4 design.

What is the minimum supply current consumption of the MKE02Z64VLC4 in its lowest power state?

The MKE02Z64VLC4 achieves a minimum supply current of 1.9 µA in Stop mode at 3 V supply and –40 to 105°C ambient temperature, with only the 1 kHz LPO clock active. This value excludes optional peripherals like ADC or ACMP; adding ADC increases current by ~41 µA. This ultra-low quiescent current makes the MKE02Z64VLC4 suitable for decade-long battery operation in remote monitoring applications.
