aIt is worth noting that VCC and VDD of optically coupled circuit should be completely isolated, or, the use of optically coupled circuit has no sense. 它值得注意到,应该完全地隔绝光学上被结合的电路VCC和VDD,或者,对光学上被结合的电路的用途没有感觉。[translate]...
1、对于数字电路来说,VCC是电路的供电电压,VDD是芯片的工作电压(通常Vcc>Vdd),VSS是接地点。 2、有些IC既有VDD引脚又有VCC引脚,说明这种器件自身带有电压转换功能。 3、在场效应管(或COMS器件)中,VDD为漏极,VSS为源极,VDD和VSS指的是元件引脚,而不表示供电电压。
The same remarks regarding polarity apply here. The strict meaning of these has been lost among a growing number of people, and hence you will often see Vcc used as the positive supply in CMOS circuits and see Vdd in BJT circuits. In many circuits, Vss/Vee is the same as the ground ...
The other two opposite corners are Vdd and Gnd. It is imperitve that these never be powered backwards (for example, by the easy mistake of the orientation being rotated 180 degrees) - the oscillators will destoy themselves essentially immediately if power is applied like that (this is almost...
file to spi flash or I2C rom is ok now.But the control center can't find out the device.I have another problem is that I use another computer can't find out the fx3 device.I made the OTG_ID pin dangling or pull up to VCC.Little effect.(Circuit is th...
VLOGIC是IO口电压,该引脚最低可以到1.8V电压, 我们一般直接连VDD即可。AD0是从IIC 接口(接 MCU)的地址控制引脚,该引脚控制的是IIC 地址的最低位。如果接 GND ,则 MPU6050的IIC地址是:0X68,如果接VDD,则是0X69。 需要注意的是:这里的地址0x68和0x69是不包含用于数据传输的最低位的,因此并不是八位数据,...

Ordering Part Number (OPN) device versions are available for core (VCC) and IO buffer (VCCQ) supplies of either 1.8V or 3.0V (nominal). Command, address, and data information is transferred over the eight HyperBus DQ[7:0] signals. The clock is used for information capture by a HyperBus...
But like I said things can be joined in multiple different ways that would be ok but not pass the ERC check. You could ignore/accept the error or set the pin to PAS (i.e. passive) which will basically ignore the check for that pin. Unless it's a very obvious...
