NXP Semiconductors MKE04Z64VLK4

Overview

MKE04Z64VLK4 from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 8 KB RAM, and 80-pin LQFP packaging, operating from 2.7–5.5 V across –40 to 105°C ambient. It integrates dual 2-channel FlexTimer/PWM modules, one 6-channel FlexTimer/PWM, RTC, 12-bit SAR ADC (16-channel), two analog comparators with 6-bit DACs, and dual I²C/SPI/UART interfaces - deployed in industrial motor control and smart sensor nodes requiring deterministic real-time response and low-power Stop mode operation.

For engineers reviewing the MKE04Z64VLK4 datasheet, MKE04Z64VLK4 pinout, MKE04Z64VLK4 application, or MKE04Z64VLK4 equivalent, this page delivers verified electrical specs, package mapping to 80-pin LQFP, validated peripheral timing (FTM, ADC, SWD), thermal resistance data (θJA = 57°C/W, 4-layer board), and confirmed alternative parts for migration paths in cost- or feature-constrained designs.

Technical Context

The MKE04Z64VLK4 implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O port access, paired with an Internal Clock Source (ICS) featuring FLL-based frequency synthesis using either internal 37.5 kHz reference or external crystal (4–24 MHz or 32.768 kHz). Its clock architecture supports dynamic switching between FEI (internal) and FBE (external) modes at runtime without reset.

System-level timing control includes three power modes (Run, Wait, Stop), programmable low-voltage detection (LVD) with four warning thresholds per range, and hardware CRC engine. Peripheral synchronization uses bus clock domain (up to 24 MHz) with dedicated synchronizers for keyboard interrupt (KBI), IRQ, and FTM inputs - ensuring reliable edge capture even during low-power transitions.

FAQ

What is the maximum operating frequency of the MKE04Z64VLK4 core?

The MKE04Z64VLK4 features an Arm Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achieved using the internal clock source (ICS) with FLL enabled and an external 8 MHz crystal, producing a stable 48 MHz system clock. The bus clock operates at half that rate (24 MHz), which governs peripheral timing including SPI, UART, and FTM modules. The MKE04Z64VLK4 datasheet confirms this rating across the full –40 to 105°C temperature range.

Does the MKE04Z64VLK4 support debugging via SWD, and what are the electrical requirements?

Yes, the MKE04Z64VLK4 supports Serial Wire Debug (SWD) using dedicated SWD_CLK and SWD_DIO pins. Per the official datasheet, SWD_CLK operates up to 24 MHz with 20 ns minimum pulse width and 3 ns rise/fall times. The interface functions across the full 2.7–5.5 V supply range, and the MKE04Z64VLK4 includes internal pull-ups on both lines to ensure reliable enumeration without external components.

What is the lowest achievable current consumption in Stop mode for the MKE04Z64VLK4?

The MKE04Z64VLK4 achieves 2 µA typical supply current in Stop mode at 5 V and 25°C, with only the 1 kHz LPO clock active. When additional modules like RTC, ADC, or LVD are enabled, additive currents apply: RTC adds <1 µA, ADC adds 86 µA, and LVD adds 130 µA. These values are measured and specified in the MKE04Z64VLK4 datasheet Table 5 under "Stop mode supply current" and are valid across –40 to 105°C.

How many analog-to-digital converter (ADC) channels does the MKE04Z64VLK4 support, and what is its resolution?

The MKE04Z64VLK4 integrates a single 12-bit successive approximation register (SAR) ADC with up to 16 input channels. It supports hardware triggering, continuous conversion mode, and operation in Stop mode - allowing low-power sensor sampling without CPU intervention. The ADC's 12-bit resolution delivers 4096 quantization levels, with integral nonlinearity (INL) and differential nonlinearity (DNL) specified in the MKE04Z64VLK4 datasheet Section 6.4.1.

Is the MKE04Z64VLK4 pin-compatible with other KE04 family members in the same package?

Yes, the MKE04Z64VLK4 is pin-compatible with all KE04 devices offered in the 80-pin LQFP package, including MKE04Z128VLK4 and MKE04Z64VLK4(R). Pin assignments for power, ground, clocks, debug, and peripheral functions are identical across these variants. This allows seamless flash-size upgrades without PCB revision - the MKE04Z64VLK4 and MKE04Z128VLK4 share identical footprint, thermal profile, and signal routing.
