概述
Description
MKM34Z256VLL7R is an NXP (Freescale) Kinetis microcontroller in the MKM34Z256 family. It uses an ARM Cortex-M0+ core optimized for low power and cost-sensitive embedded designs. The MCU includes up to 256 KB of on-chip flash memory, on-chip RAM, and a broad peripheral set (GPIO, timers, ADC/DAC, serial interfaces such as I2C/SPI/UART, USB, etc.) plus low-power modes and various package options. The VLL7R suffix denotes a specific LQFP-style package and revision. It targets small-to-mid range control, sensing, and communications tasks in automotive, consumer, and industrial applications. For exact specifications (RAM size, clock speed, voltage range, package details, and peripheral counts), consult NXP’s official MKM34Z256 datasheet and reference manuals.
