PCA9564 Description
The PCA9564 is an integrated circuit designed in CMOS technology that serves as an interface between most standard parallel-bus microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus system to municate bi-directionally with the I2C-bus. The PCA9564 can operate as a master or a slave and can be a transmitter or receiver. munication with the I2C-bus is carried out on a byte-wise basis...
