NXP Semiconductors MKE02Z64VLD4R

Overview

MKE02Z64VLD4R from NXP Semiconductors is a 40 MHz Arm® Cortex-M0+ microcontroller with 64 KB flash, 4 KB RAM, and 256 B EEPROM, operating across –40 to 105°C at 2.7–5.5 V. It integrates a 12-bit SAR ADC (16-channel), dual analog comparators with 6-bit DACs, three UARTs, two SPIs, one I²C, six FTM/PWM channels, RTC, and SWD debug - deployed in industrial motor control, smart sensors, and battery-powered HMI systems.

For engineers reviewing the MKE02Z64VLD4R datasheet, MKE02Z64VLD4R pinout, MKE02Z64VLD4R application, or MKE02Z64VLD4R equivalent, this page delivers verified electrical specs, package mapping to 44-pin LQFP (10 mm × 10 mm), validated peripheral timing, low-power Stop-mode current (2 µA), and direct alternative part comparisons - all grounded in NXP's KE02 Sub-Family Data Sheet Rev. 6 (12/2019).

Technical Context

The MKE02Z64VLD4R 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 a trimmable FLL for up to 40 MHz system clock and a 1 kHz low-power oscillator (LPO). Its memory subsystem includes 64 KB flash with read-while-write capability, 4 KB SRAM, and 256 B EEPROM with 100K write cycles.

Peripherals are tightly integrated for deterministic real-time operation: three UART modules support asynchronous serial communication with configurable baud rates; two SPI controllers operate up to 20 MHz bus clock; one I²C module complies with standard/fast-mode (100/400 kHz); and the FlexTimer subsystem provides six independent PWM/compare channels plus periodic interrupt timers - all synchronized to the 20 MHz bus clock.

FAQ

What is the maximum operating frequency of the MKE02Z64VLD4R?

The MKE02Z64VLD4R features an Arm Cortex-M0+ core with a maximum system clock frequency of 40 MHz and a bus clock limit of 20 MHz. This is achieved via the internal clock system (ICS) with a trimmable FLL using either internal reference (31.25 kHz pre-trimmed) or external crystal/resonator. The MKE02Z64VLD4R datasheet confirms this specification under "Performance" and "Control timing" sections (Table 7, fSys = 40 MHz).

Does the MKE02Z64VLD4R support analog-to-digital conversion?

Yes, the MKE02Z64VLD4R integrates a 12-bit successive approximation register (SAR) ADC with up to 16 input channels. It operates in Run, Wait, and Stop modes, supports hardware triggering, and includes configurable sample time and resolution. The ADC is explicitly documented in the KE02 Sub-Family Data Sheet Section 6.4.1 and Table 6.4.1 (ADC characteristics), confirming its use in low-power sensing applications.

What package type does the MKE02Z64VLD4R use?

The MKE02Z64VLD4R uses a 44-pin LQFP package (10 mm × 10 mm, 0.8 mm pitch), identified by the "LD" suffix in its part number per NXP's KE02 naming convention (Section 2.3, PP field). This is distinct from QFP (QH), QFN (FM), or smaller LQFP variants - and is confirmed in the "Package options" section of the KE02 Sub-Family Data Sheet (Rev. 6, p.2).

Can the MKE02Z64VLD4R operate in ultra-low-power modes?

Yes, the MKE02Z64VLD4R supports three power modes: Run, Wait, and Stop. In Stop mode with no peripherals active, typical supply current is 2 µA at 5 V (–40 to 105°C), rising to 86 µA when ADC is enabled. These values are specified in Table 5 ("Supply current characteristics") of the KE02 Sub-Family Data Sheet, enabling multi-year battery life in intermittent-sensing applications.

What communication interfaces are integrated into the MKE02Z64VLD4R?

The MKE02Z64VLD4R integrates two SPI modules, up to three UART modules, and one I²C module. All are fully functional at the 20 MHz bus clock rate. UART supports standard asynchronous framing; SPI supports master/slave modes up to 20 MHz; I²C complies with standard/fast-mode (100/400 kHz). These are listed in the "Communication interfaces" section and verified in peripheral timing tables (Sections 5.2.1–5.2.2).
