                                                PCA9665APW,118 Overview
There is a copy of it in the 20-TSSOP (0.173, 4.40mm Width) package. Carrying is easy with the Cut Tape (CT)-shaped packaging. Keeping the temperature at -40°C~85°C will ensure reliable operation. You should be able to use it as long as you use 2.3V~3.6VV power. There are 20 terminations in this circuit. When 2.5V is used as the supply voltage, high efficiency can be achieved. As a member of the PCA9665A family, it is a prime number. As far as the device's clock is concerned, it runs at the frequency of 32MHz. There is a supply of 100μA at the moment.
