2-Wire Communication
Writing to a Slave: The master must generate a START
condition, write the slave address (R/W = 0), write the
memory address, write the byte of data, and generate a
STOP condition. Remember the master must read the
slave’s acknowledgement during all byte-write opera-
tions. See Figure 2 for the write command example.
Reading from a Slave: To read from the slave, the
master generates a START condition, writes the slave
address with R/W = 1, receives an ACK from the slave,
reads a memory address of 00h from the slave, sends
an ACK to the slave, reads the data byte, then sends
an ACK to indicate the end of the transfer, and gener-
ates a STOP condition. See Figure 2 for the read com-
mand example.
Application Information
Power-Supply Decoupling
To achieve the best results when using the DS4302,
decouple the power supply with a 0.01F or a 0.1F
capacitor. Use high-quality, ceramic, surface-mount
capacitors, and mount the capacitors as close as pos-
sible to the VCC and GND pins of the DS4302 to mini-
mize lead inductance.
SDA and SCL Pullup Resistors
Pullup resistor values for SDA and SCL should be cho-
sen to ensure that the rise and fall times listed in the AC
electrical characteristics are within specification.
