5、3.3V 电源电压,支持串口低功耗睡眠模式。
6、芯片功能相当于CH365芯片加CH438芯片,提供6串口、16串口以及更多串口等应用方案。
7、LQFP-128无铅封装,兼容RoHS。
串口
1、完全独立的8个异步串口,兼容16C550、16C552、16C554及16C750并且有所增强。
2、支持5、6、7或者8个数据位以及1或者2个停止位。
3、支持奇、偶、无校验、空白0、标志1等校验方式。
4、可编程通讯波特率,支持115200bps以及最高达4Mbps的通讯波特率。
5、内置128字节的FIFO先进先出缓冲器,支持4个FIFO触发级。
6、支持MODEM调制解调器信号CTS、DSR、RI、DCD、DTR、RTS,可由75232芯片转成RS232电平。
7、支持硬件流控制信号CTS 和RTS自动握手和自动传输速率控制,兼容TL16C550C。
8、支持串口帧错误检测、支持Break线路间隔检测。
9、支持全双工和半双工串口通讯。
10、串口0内置SIR红外线编解码器,支持2400bps到115200bps 波特率的IrDA 红外通讯。
并口
