ACT-IR8200D
Design Specification
4. Device Operation
4.1
RESET circuit
IR8200D will be reset when RESET_IN is pulled
low. It needs a 10K ohms resistor, 0.1uF
capacitor and a diode to implement the reset
circuit. Please refer to right figure.
4.2
Crystal circuit
IR8200D needs a specific
clock to operate, please refer
to right figure.
4.3
Host Interface
The host interface of IR8200D is a full-duplex asynchronous serial data interface. The data bytes are
transmitted via TX and received via RX. Each data byte consists of one start bit (0), 8 data bits (LSB
first, MSB last) and a stop bit (1).
