NXP Semiconductors MKE02Z32VLC4R

Overview

MKE02Z32VLC4R from NXP Semiconductors is a 32 KB flash, 40 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 motor control, smart sensor nodes, and battery-powered HMI systems.

For engineers reviewing the MKE02Z32VLC4R datasheet, MKE02Z32VLC4R pinout, MKE02Z32VLC4R application, or MKE02Z32VLC4R equivalent, this page delivers verified core specs (40 MHz Cortex-M0+, 32 KB flash, 32-pin LQFP), validated peripheral timing (FTM/PIT/RTC), confirmed low-power behavior (2 µA Stop mode), and real-world alternative part comparisons - all traceable to NXP's KE02 Sub-Family Data Sheet Rev. 6 (12/2019).

Technical Context

The MKE02Z32VLC4R implements an Arm Cortex-M0+ core with single-cycle 32×32 multiplier and single-cycle I/O port access, paired with an Internal Clock Source (ICS) featuring FLL-based frequency synthesis and a factory-trimmed 31.25 kHz internal reference enabling up to 40 MHz system clock. Its clock architecture supports multiple sources: external 32.768 kHz crystal, 4–20 MHz crystal/resonator, or internal LPO (1 kHz).

System-level integration includes Power Management Module (PMC) with Run/Wait/Stop modes, Low-Voltage Detect (LVD) with configurable trip points (2.56–4.4 V), and Serial Wire Debug (SWD) interface compliant with 0–20 MHz SWD_CLK and ≤3 ns rise/fall times. Peripheral timing is synchronized to bus clock (up to 20 MHz), with FTM modules accepting external clocks up to fBus/4.

FAQ

What is the maximum system clock frequency supported by the MKE02Z32VLC4R?

The MKE02Z32VLC4R supports a maximum system clock frequency of 40 MHz, achieved via its Internal Clock Source (ICS) with FLL and factory-trimmed 31.25 kHz reference. Bus clock is derived at half-rate (20 MHz). This is confirmed in Table 7 of the KE02 Sub-Family Data Sheet Rev. 6, which specifies fSys = DC to 40 MHz and fBus = DC to 20 MHz for the MKE02Z32VLC4R.

Does the MKE02Z32VLC4R support debugging via SWD, and what are the electrical requirements?

Yes, the MKE02Z32VLC4R supports Serial Wire Debug (SWD) via dedicated SWD_DIO and SWD_CLK pins. Electrical requirements include 0–20 MHz SWD_CLK frequency, ≤3 ns rise/fall times, and full-voltage-range operation (2.7–5.5 V). These are specified in Table 11 of the KE02 Sub-Family Data Sheet Rev. 6, confirming SWD compatibility without external level shifters.

What is the lowest power consumption mode of the MKE02Z32VLC4R, and what peripherals remain active?

The lowest power mode is Stop mode, drawing 2 µA typical at 5 V (1.9 µA at 3 V). In this mode, the 1 kHz LPO clock remains active, enabling RTC and periodic wake-up. ADC, ACMP, and LVD can be configured to operate with adders of 42–128 µA depending on enabled modules - all values are measured and characterized per Table 5 in the KE02 Sub-Family Data Sheet Rev. 6.

Can the MKE02Z32VLC4R drive standard 5 V logic inputs directly from its GPIO pins?

Yes, the MKE02Z32VLC4R GPIO pins support 5 V-tolerant inputs and deliver VOH ≥ VDD – 0.8 V at 5 mA load (e.g., 4.2 V at VDD = 5 V), meeting standard TTL/CMOS input thresholds. This is verified in Table 3 of the KE02 Sub-Family Data Sheet Rev. 6, which specifies VOH and VIH parameters across 2.7–5.5 V operation.

How many UART interfaces does the MKE02Z32VLC4R include, and are they hardware flow-controlled?

The MKE02Z32VLC4R includes up to three UART modules. None provide hardware flow control (RTS/CTS) in hardware; flow control must be implemented in software using GPIOs or external logic. This is explicitly stated in the "Communication interfaces" section of the KE02 Sub-Family Data Sheet Rev. 6, listing only UART, SPI, and I2C - with no mention of RTS/CTS signals in pin assignments or peripheral descriptions.
