MKE04Z8VFK4R

Microcontrollers Overview

The MKE04Z8VFK4R is an ARM Cortex-M0+ microcontroller from the Kinetis KE04 series, featuring 8 KB of Flash memory and 1 KB of RAM. It operates at a maximum frequency of 48 MHz with a supply voltage range of 2.7 V to 5.5 V. The device includes a 12-bit ADC, two analog comparators with integrated DACs, and communication interfaces such as SPI, UART, and I2C. It is housed in a 24-pin QFN package.

Microcontrollers Feature Summary

• Integrated Serial Wire Debug (SWD) interface for programming and debugging
• Supports multiple low-power modes including Run, Wait, and Stop
• Includes programmable cyclic redundancy check (CRC) module
• Features bit manipulation engine (BME) and aliased SRAM bitband region

Microcontrollers Applications

• General-purpose embedded control systems
• Battery-powered applications requiring low power consumption
• Industrial control and automation devices
• Human-machine interface (HMI) components

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'R' corresponds to tape and reel packaging when sourcing. Confirm that the 24-pin QFN package matches your board layout requirements. Ensure compatibility with the KE04 sub-family reference manual for peripheral configuration. Check for moisture sensitivity level 3 handling requirements during assembly.

Microcontrollers Selection Notes

Select this component for designs requiring a balance of processing capability and low power consumption. The 48 MHz Cortex-M0+ core provides sufficient performance for many control tasks. Consider the 2.7 V to 5.5 V operating range for flexibility in power supply design. Evaluate the available GPIO count against system interface needs.

Microcontrollers Part Context

This part belongs to the NXP Kinetis KE04 family, designed for cost-sensitive and power-efficient applications. It shares architectural similarities with other KE04 variants but differs in memory size and package options. The device is suitable for replacing older 8-bit or lower-performance 32-bit MCUs in modern embedded designs.

Microcontrollers Replacement Considerations

Compatible substitutes within the KE04 family include MKE04Z8VTG4 and MKE04Z8VWJ4, differing primarily in package type. Verify pinout compatibility when switching between QFN, TSSOP, and SOIC packages. Memory and peripheral configurations remain consistent across these variants.
