PL2303SA在运行或暂停模式下的功耗非常小，非常适合总线供电运行，并为连接的设备提供充足的电力。类似RS232的串行端口侧的灵活信号电平要求也允许PL2303SA直接连接到任何3.3V~1.8V范围的设备。发布日期：2013年3月27日，2018 DS_PL2303SA_d20180327_v1.2.0.doc PL2303SA产品数据表-9-文档版本1.2.0 4.0引脚分配图PL-2303SA 1 2 TXD 3 4 VDD_325 RXD 5 6 7 8 VDD_5 GND VO_33 DM DP图4-1 PL2303SB SOP8封装5.0引脚分配描述引脚类型缩写：I：输入O：输出B：双向I/O P：电源/接地表5-1引脚分配描述（SOP8封装）引脚#名称类型描述1 GND P接地2 TXD O（1）串行端口（传输数据）3 VDD_325 P RS232 VDD。串行端口信号的电源引脚。当串行端口为3.3V时，应为3.3V。当串行端口为2.5V时，应为2.5V。电压范围为1.8V～3.3V。4 RXD I（2）串行端口（接收数据）5 DP B USB端口D+信号6 DM B USB端口D-信号7 VDD_5 P USB端口VBUS，5V电源8 VO_33 P稳压器电源输出，3.3V注释：（1）–三态，输出板。电平和驱动能力由VDD_325决定。（2）–带电平移位器的三态CMOS输入/输出焊盘。级别和驱动能力由VDD_325决定。发布日期：2018年3月27日DS_PL2303SA_d20180327_1.2.0.doc PL2303SA产品数据表-10-文档版本1.2.0 6.0数据格式和可编程波特率生成器PL2303SB控制器支持多种数据格式，并具有可编程波特率发生器。支持的数据格式如表6-1所示。可编程波特率生成器支持75 bps至115 kbps的波特率，如表6-2所示。表6-1支持的数据模式描述停止位1 1.5 2奇偶类型无奇偶标记空间数据位5、6、7、8表6-2驱动程序
With very small power consumption in either operating or suspend mode, PL2303SA is perfect for bus powered operation with plenty of power left for the attached devices. Flexible signal level requirement on the RS232-like serial port side also allows PL2303SA to connect directly to any 3.3V~1.8V range devices.
