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...
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...

ToDestination 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...
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...
因此我们在拿到实际板子后需要对I2C信号进行SI测试,根据测试结果再对上拉电阻的阻值进行微调。 四、I2C总线信号质量常见问题及解决方法 见I2C信号质量优化 (会持续更新) 参考文献 Understanding the I2C Bus I2C Bus Pullup Resistor Calculation UM10204 I2C-bus specification and user manual...
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...
