PM856K01/3BSE018104R1系统模块备件
设备电源模式总线供电（100mA）此字段设置USB设备是总线供电还是自供电设备。最大功率100mA此字段以mA为单位设置USB设备的最大功率。如果不是100mA或500mA，请在此处输入值。以2 mA单位表示（即50=100 mA）。USB选择性挂起启用此字段启用/禁用USB。请参阅示意图了解详细的电容值。图10-2a IO电源VDD_IO也可以由其他电源提供，以提供不同的I/O电压。此提供的VDD_IO电压不应大于VIN电压。所有PL2303GL I/O引脚使用相同的VDD_IO电压。I/O引脚不支持混合I/O电压。除非开启漏极选项，否则两个芯片之间的I/O连接应使用相同的VDD_IO电压。PL2303GL I/O引脚还支持5V容差，允许在不同VDD_IO电压下的5V输入信号电平。图10-2b VDD_IO电压源VBUS DD+GND稳压器VIN VO_33 PL2303GL USB连接器VDD_IO稳压器VIN VO_3 3 PL2303GL VDD_IO电源IO电压VDD_IO TXD RXD TX RX C1 C2产品数据表PL2303GL发布：2018年12月6日-20/23-版本0.8 11。直流和温度特性11.1绝对最大额定值表11-1绝对最大额定电压项目额定值电源电压-VIN-0.3至6.0 V输入电压VDD_IO-0.3至VIN+0.3 V输入电压输入/输出5V容差I/O-0.3至6.0V存储温度-40至150°C注：如果超过绝对最大额定，可能会导致永久性设备损坏。这些只是应力等级，功能操作应限制在条件内。长时间暴露在绝对最大额定条件下可能会影响设备的可靠性。11.2直流特性11.2.1工作电压和暂停电流表11-2a工作电压和停止电流参数符号最小典型值最大单位电源电压范围VIN 2.8 5 5.5 V输入/输出引脚VDD_IO 1.8 3.3 VIN+0.3 V稳压器输出电压VO_33 2.97 3.3 3.63 V工作电流（1）（功耗）IDD-9.5 15 mA暂停电流ISUS-250 450 mA注：（1）–未连接设备。11.2.2 I/O引脚表11-2b I/O引脚参数符号最小类型最大单位输入电压（CMOS）低-高VIL VIH--0.7*VDD_IO---0.4--VV输出电压低-高VOL VOH--0.7*VDD_IO---0.4--V 11.3温度特性表11-3温度特性参数符号最小典型最大单位工作温度（环境）--40--85°C结工作温度TJ-40 25125 o C产品数据表PL2303GL版本：2018年12月6日-21月23日-修订版0.8 12.外形图12.1 SOP8包装图12-1 PL2303GL外形图（SOP8）产品数据表PL 2303GL发布：2018年11月6日-22月23日–修订版0.8 12.2 UDFN8包装图12-2 PL2303G L外形图（UDFN8），18-23/23-修订版0.8免责声明本文档中的所有信息如有更改，恕不另行通知。Prolific Technology Inc.不对本文件的准确性和完整性做出任何陈述或保证（暗示或其他），并且在任何情况下都不对任何利润损失或任何其他商业损害负责，包括但不限于特殊、偶然、后果性或其他损害。商标Prolific徽标是Prolifice Technology Inc.的注册商标。
Device Power Mode Bus Powered (100mA) This field sets the USB device if bus-powered or self-powered device. Max Power 100mA This field sets the USB device maximum power in mA. Enter the value here if it is not 100mA or 500mA. Expressed in 2 mA units (i.e., 50 = 100 mA). USB Selective Suspend Enable This field enables/disables the USB Please refer to schematic for the detailed capacitor value.. Figure 10-2a IO Power Supply VDD_IO can also be supplied from other power source to provide different I/O voltage. This supplied VDD_IO voltage should not be larger than VIN voltage. All of the PL2303GL I/O pins use the same VDD_IO voltage. The I/O pins does not support mixed I/O voltages. Unless open-drain option is enabled, the I/O connection between two chips shall use the same VDD_IO voltage. PL2303GL I/O pin also supports 5V tolerance which allows 5V input signal level in different VDD_IO voltage.
