ICS1526 Preliminary Data Sheet
Section 1 Overview
1.4 I
2
C Bus Serial Interface
The ICS1526 uses a 5 volt tolerant, industry-standard
I
2
C-bus serial interface that runs at either low speed
(100 kHz) or high speed (400 kHz). The interface uses
12 word addresses for control and status: one
write-only, eight read/write, and three read-only
addresses.
Two ICS1526 devices can sit on the same I
2
C bus,
each selected by the Master according to the state of
the I2CADR pin. The 7-bit device address is 0100110
(binary) when I2CADR is low. The device address is
0100111 (binary) when I2CADR is high. See
