AT89C51CC02 / T89C51CC02 概述
Low pin count 8-bit microcontroller with CAN controller and 16-Kbyte Flash
We recommend to implement an external brown out to prevent any Flash/EEPROM corruption during power-on or power-off. Please refer to related application note: External Brown-out Protection for C51 Microcontrollers with Active High Reset Input
