NXP Semiconductors MKE02Z32VLC2R

Overview

MKE02Z32VLC2R from NXP Semiconductors is a 32 KB flash, 20 MHz Arm® Cortex-M0+ microcontroller in 32-pin LQFP (7 mm × 7 mm), operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates 4 KB RAM, 256 B EEPROM, 12-bit SAR ADC with Stop-mode operation, dual analog comparators with 6-bit DACs, and three UARTs - deployed in industrial sensor nodes and motor control subsystems.

For engineers reviewing the MKE02Z32VLC2R datasheet, MKE02Z32VLC2R pinout, MKE02Z32VLC2R application, or MKE02Z32VLC2R equivalent, key selection criteria include its 32-pin LQFP footprint, 20 MHz core clock with FLL-based ICS, low-power Stop mode (2 µA typical), integrated SWD debug interface, and support for hardware-triggered ADC conversions in deep-sleep states.

Technical Context

The MKE02Z32VLC2R implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access. Its internal clock system combines an FLL with trimmable 31.25 kHz reference for up to 20 MHz system clock, plus independent 1 kHz LPO for RTC and low-power wake-up.

Peripherals include one 6-channel FlexTimer/PWM (FTM), two 2-channel FTM modules, one periodic interrupt timer (PIT), real-time clock (RTC), two SPI, three UART, and one I²C interface - all accessible via multiplexed GPIO pins on the 32-pin LQFP package with configurable drive strength and programmable pull-ups.

FAQ

What is the maximum system clock frequency supported by the MKE02Z32VLC2R?

The MKE02Z32VLC2R supports a maximum system clock frequency of 20 MHz, achieved via its internal FLL with trimmable 31.25 kHz reference oscillator. This frequency is fully specified across the –40 to 105°C temperature range and 2.7–5.5 V supply, and is used for core execution, bus timing, and peripheral clock derivation. The MKE02Z32VLC2R datasheet confirms this rating under "Performance" and "Control timing" sections.

Does the MKE02Z32VLC2R support ADC conversions while in Stop mode?

Yes, the MKE02Z32VLC2R supports hardware-triggered ADC conversions during Stop mode, with typical supply current of 2 µA plus adders (e.g., +42 µA for ADC active). The ADC module remains clocked by the 1 kHz LPO or other enabled sources, enabling low-power sensor sampling without waking the CPU. This behavior is documented in Table 5 ("Supply current characteristics") and Section 6.4.1 ("ADC characteristics") of the KE02 Sub-Family Data Sheet.

What debug interface does the MKE02Z32VLC2R use, and how many pins are required?

The MKE02Z32VLC2R uses Serial Wire Debug (SWD), requiring only two pins: SWD_DIO and SWD_CLK. This 2-pin interface supports full memory access, breakpoint setting, register inspection, and real-time trace at up to 20 MHz clock rate. SWD replaces JTAG to reduce pin count and simplify board layout, and is electrically characterized in Table 11 ("SWD full voltage range electricals") of the MKE02Z32VLC2R datasheet.

What is the purpose of the 64-bit unique identification number in the MKE02Z32VLC2R?

The MKE02Z32VLC2R includes a factory-programmed 64-bit unique identification number used for secure device authentication, firmware binding, and anti-cloning measures. It is read-only, non-erasable, and guaranteed unique per die. This feature supports secure boot validation and device-specific encryption keys in applications like smart meters and medical devices, as specified in the "Security and integrity modules" section of the KE02 Sub-Family Data Sheet.

Can the MKE02Z32VLC2R operate from a 3.3 V supply, and what are the I/O voltage tolerances?

Yes, the MKE02Z32VLC2R operates from 2.7–5.5 V, including standard 3.3 V rails. Its digital I/O pins tolerate input voltages up to VDD + 0.31 V (so up to 3.61 V at 3.3 V supply), and output high voltage is VDD – 0.8 V (≥2.5 V at 3.3 V). True open-drain pins PTA2/PTA3 are clamped only to VSS and accept up to 6 V inputs. These values are confirmed in Table 2 ("Voltage and current operating ratings") and Table 3 ("DC characteristics").
