I5216 SERIES
Advanced Information
PRELIMINARY
I2C SLAVE ADDRESS
The I5216 has a 7 bit slave address of <100 00xy> where x and y are equal to the state, respectively,
of the external address pins A1 and A0. Because all data bytes are required to be 8 bits, the LSB of the
address byte is the Read/Write selection bit that tells the slave whether to transmit or receive data.
Therefore, there are eight possible slave addresses for the I5216
