NXP MKL43Z256VLH4

ARM® Cortex®-M0+48MHz256KB（256K x 8）

Overview

The MKL43Z256VLH4 is a 32-bit Kinetis KL4x Ultra-low-power Microcontroller with USB and segment LCD control, based on ARM Cortex-M0+ RISC architecture core operates at a maximum frequency of 48MHz. The device incorporates 256kB internal flash, 16kB boot ROM, 32kB internal RAM, one 16-bit SAR A/D converter, one 12-bit D/A converter, general purpose PWM and 50 general-purpose I/O pins. This device also features communication interfaces like three UART modules, one I2S module, two SPI modules and two I2C modules.
