NXP Semiconductors MC9S08SU 8位微控制器
NXP Semiconductors MC9S08SU 8位微控制器(MCU)是面向低端4.5V至18.0V电机控制应用的单芯片解决方案，具有低BOM成本和紧密集成。基于HSC08内核，MC9S08SU MCU可通过增强型S08L中央处理器单元和3相MOSFET预驱动器单元实现高性能并保持低成本，并可支持3个高侧PMOS和3个低侧NMOS以及放大器，从而进行电流测量、过流保护(OCP)和过压保护(OVP)。MC9S08SU MCU采用紧凑型4mm x 4mm QFN-24封装。MC9S08SU的尺寸小，所需元件数量也少，因此非常适合用于空间受限的应用，如电动工具、无人机和机器人技术。
