NXP Semiconductors MKE04Z8VTG4R

Overview

MKE04Z8VTG4R from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 8 KB flash, 1 KB RAM, and integrated analog peripherals including a 12-bit SAR ADC and dual analog comparators - deployed in industrial sensor nodes and low-power motor control interfaces.

For engineers reviewing the MKE04Z8VTG4R datasheet, MKE04Z8VTG4R pinout, MKE04Z8VTG4R application, or MKE04Z8VTG4R equivalent, key selection criteria include its -40 to 105°C operating range, 16-pin TSSOP package, 2.7–5.5 V supply, SWD debug interface, and Stop-mode current as low as 2 µA - critical for battery-powered embedded systems requiring deterministic real-time response.

Technical Context

The MKE04Z8VTG4R 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 system (ICS) featuring FLL-based 48 MHz generation from a 32.768 kHz crystal or 4–24 MHz resonator. Its power management includes Run/Wait/Stop modes, LVD with selectable trip points, and independent 1 kHz LPO for RTC operation during Stop.

Peripherals include two FlexTimer/PWM modules (6-channel + 2-channel), one PIT, one PWT, one RTC, SPI/I²C/UART interfaces, and a programmable CRC engine. Analog functions comprise a 12-channel 12-bit ADC with Stop-mode operation and two ACMPs each integrating a 6-bit DAC and programmable reference input.

FAQ

What is the maximum operating frequency of the MKE04Z8VTG4R?

The MKE04Z8VTG4R operates at up to 48 MHz via its Arm Cortex-M0+ core, with bus frequency limited to 24 MHz. This frequency is achieved using the internal FLL clock system locked to either an external 32.768 kHz crystal or a 4–24 MHz resonator. The device maintains full specification compliance across its -40 to 105°C ambient temperature range at this speed.

Does the MKE04Z8VTG4R support debugging during low-power modes?

Yes, the MKE04Z8VTG4R supports Serial Wire Debug (SWD) while in Run and Wait modes. In Stop mode, SWD is disabled to preserve ultra-low current; however, the device can be woken by external interrupt or RTC alarm and then re-enter debuggable state. SWD_CLK operates up to 24 MHz, and SWD_DIO timing meets JTAG/SWD protocol requirements per NXP's characterization data.

How much current does the MKE04Z8VTG4R draw in Stop mode with RTC enabled?

The MKE04Z8VTG4R draws 2 µA typical supply current in Stop mode with only the 1 kHz LPO clock active. Enabling the RTC adds less than 1 µA, resulting in ≤3 µA total. This value is measured at 5 V and 25°C; at 3 V and 105°C, maximum Stop current remains below 40 µA per datasheet Table 5 - enabling multi-year operation on coin-cell batteries.

Can the MKE04Z8VTG4R's ADC operate while the core is in Stop mode?

Yes, the 12-bit SAR ADC in the MKE04Z8VTG4R can perform conversions in Stop mode using hardware triggers such as the periodic interrupt timer (PIT) or external pin events. Conversion results are stored in memory without CPU involvement, and an interrupt wakes the core upon completion. This capability is confirmed in Section 6.4.1 of the KE04 Sub-Family Data Sheet Rev. 5.

What package type and dimensions does the MKE04Z8VTG4R use?

The MKE04Z8VTG4R uses a 16-pin TSSOP package (TG suffix), measuring 4.5 mm × 5 mm with 0.65 mm pitch. It features an exposed thermal pad on the underside for improved heat dissipation and complies with JEDEC MO-153 standards. Pin 1 is marked by a dot; the package is RoHS-compliant and rated MSL-3 per J-STD-020.
