Texas Instruments Incorporated I2C Bus Pullup Resistor Calculation 3 Speed Versus Power Trade-off www.ti.com 3 Speed Versus Power Trade-off Once the minimum and maximum value of the pullup resistor has been selected, the decision for the value of resistor can be made based on trade-off betwe...
I2C Bus Pullup Resistor Calculation UM10204 I2C-bus specification and user manual
SCL和SDA均需要通过上拉电阻连接到Vcc。上拉电阻的大小由I2C线路上的等效电容大小决定(想要了解更多,可以参考TI的I2C Pull-up Resistor Calculation这份文档,文档号:SLVA689;也可以看我的笔记里面的文章《I2C上升沿过长与上拉电阻》)。数据传送只能在总线空闲时初始化。如果SDA和SCL在一个STOP标志后均处于高电平状态...
A customer's design wants to adjust the pull_ups value for their I2C interface, how to decide to accept their change? Is there a correct resistance value for I2C pull-up resistors? I2C Bus Pullup Resistor Calculation by TI
the value range of tr and tlow according to the line characteristics of an I2C bus working under a fast mode, and thereby work out the value range of R according to the value range and a calculation formula including the tr and tlow of the resistance R of an I2C pull-up resistor. Th...
I2C_Pullup_Resistor_CalculationSt**en 上传281.49 KB 文件格式 zip I2C是一种常用的串行通信协议,用于连接微控制器和外设。在I2C总线上,为了确保数据传输的可靠性,需要使用上拉电阻来提供总线上的恢复电流。 I2C上拉电阻的计算需要考虑两个主要因素:总线电容和总线速度。总线电容是指总线上所有设备的电容负载,包括...
上拉电阻的大小由I2C线路上的等效电容大小决定(想要了解更多,可以参考TI的I2CPull-up Resistor Calculation这份文档,文档号:SLVA689;也可以看我的笔记里面的文章《I2C上升沿过长与上拉电阻》)。数据传送只能在总线空闲时初始化。如果SDA和SCL在一个STOP标志后均处于高电平状态,这时可以认为总线处在空闲状态。
上拉电阻的大小由I2C线路上的等效电容大小决定(想要了解更多,可以参考I2C Pull-up Resistor Calculation这份文档,文档号:SLVA689)。数据传送只能在总线空闲时初始化。如果SDA和SCL在一个STOP标志后均处于高电平状态,这时可以认为总线处在空闲状态。主机访问从机的大体流程如下所示: 假设一个主机想要向从机发送数据: ...
上拉电阻的大小由I2C线路上的等效电容大小决定(想要了解更多,可以参考TI的I2C Pull-up Resistor Calculation这份文档,文档号:SLVA689,也可以看讲解 I2C 信号线为何加上拉电阻)。 数据传送只能在总线空闲时初始化。如果SDA和SCL在一个STOP标志后均处于高电平状态,这时可以认为总线处在空闲状态。
The size of the pull-up resistor is determined by the amount of capacitance on the I2C lines. For further details, see I2C Pull-up Resistor Calculation application report, SLVA689. Data transfer may be initiated only when the bus is idle. A bus is considered idle if both SDA and SCL ...
