Issue Details

What is the capacitor value for the SCL and SDA pins of USB-8451 and USB-8452?

Solution

There is no specification data for USB-8451.However, only 8051 MCU pin capacitor , traces and connector contribute. Therefore , should be less than 100 pF.

For USB-8451 maximum capacitance value is 70 pF.
