NXP Semiconductors MKE02Z32VLC4

Overview

MKE02Z32VLC4 from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller with 32 KB flash, 4 KB RAM, and 256 B EEPROM, operating at up to 40 MHz core frequency and supporting -40°C to 105°C ambient temperature. It integrates a 12-bit SAR ADC, dual analog comparators with 6-bit DACs, FlexTimer/PWM modules, UART/I²C/SPI interfaces, and low-power Stop mode (41 µA typical), targeting cost-sensitive industrial control and sensor interface applications.

For engineers reviewing the MKE02Z32VLC4 datasheet, MKE02Z32VLC4 pinout, MKE02Z32VLC4 application, or MKE02Z32VLC4 equivalent, key selection criteria include its 32-pin LQFP (7 mm × 7 mm) package, 2.7–5.5 V supply range, integrated SWD debug interface, real-time clock, and support for hardware-triggered ADC operation in Stop mode.

Technical Context

The MKE02Z32VLC4 implements an ARM Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access. Its clock system combines an internal FLL (with 31.25 kHz pre-trimmed reference enabling up to 40 MHz system clock) and external crystal support (32.768 kHz or 4–20 MHz).

Power management includes three modes-Run, Wait, and Stop-with Stop mode consuming 41 µA (32-pin package) and retaining RAM/RTC while allowing ADC and ACMP wake-up. The device features programmable cyclic redundancy check (CRC), bit manipulation engine (BME), and 64-bit unique chip ID for secure identification.

FAQ

What is the maximum operating frequency of the MKE02Z32VLC4 core?

The MKE02Z32VLC4 features an ARM Cortex-M0+ core rated for up to 40 MHz operation. This frequency is achieved using the internal FLL with trimming, or via external crystal/resonator sources. Bus clock runs up to 20 MHz. All timing specifications-including ADC conversion, PWM resolution, and peripheral synchronization-are validated at this maximum frequency across the full -40°C to +105°C temperature range.

Does the MKE02Z32VLC4 support debugging during low-power modes?

Yes, the MKE02Z32VLC4 supports Serial Wire Debug (SWD) in Run and Wait modes. In Stop mode, SWD is disabled to preserve power, but the device can be woken by peripherals (e.g., ADC completion or ACMP event) and then re-enter debuggable state. SWD_CLK operates up to 20 MHz and requires only two pins, making it ideal for space-limited designs where JTAG is impractical.

How much current does the MKE02Z32VLC4 consume in Stop mode?

The MKE02Z32VLC4 consumes 41 µA typical in Stop mode when configured with the 32-pin LQFP package, 5 V supply, and only the 1 kHz LPO clock active. This value increases by known adders if peripherals like ADC (86 µA), ACMP (12 µA), or LVD (128 µA) are enabled. All Stop mode current values are characterized across -40°C to +105°C and published in Table 5 of the KE02 Sub-Family Data Sheet (Rev. 6).

Can the MKE02Z32VLC4's ADC operate while the MCU is in Stop mode?

Yes, the 12-bit SAR ADC in the MKE02Z32VLC4 can perform conversions in Stop mode when configured with hardware triggering (e.g., from a timer or external pin). Conversion results are stored in registers and generate an interrupt upon completion, waking the core. This capability enables ultra-low-power sensor sampling without CPU intervention-critical for battery-operated endpoints.

What package type does the MKE02Z32VLC4 use, and what are its key mechanical attributes?

The MKE02Z32VLC4 uses a 32-pin LQFP package measuring 7 mm × 7 mm with 0.8 mm pitch. It has moisture sensitivity level 3 (MSL3), requires lead-free reflow per J-STD-020, and features exposed thermal pad grounding for improved heat dissipation. Pin assignments and signal multiplexing are fully documented in Section 8 of the KE02 Sub-Family Data Sheet (Rev. 6).
