PCA9634
8-bit Fm+ I 2 C-bus LED driver
7. Functional description
Refer to Figure 1 “Block diagram of PCA9634” .
7.1 Device addresses
Following a START condition, the bus master must output the address of the slave it is
accessing.
There are a maximum of 128 possible programmable addresses using the 7 hardware
address pins. Two of these addresses, Software Reset and LED All Call, cannot be used
because their default power-up state is ON, leaving a maximum of 126 addresses. Using
other reserved addresses, as well as any other Sub Call address, will reduce the total
number of possible addresses even further.
7.1.1 Regular I 2 C-bus slave address
The I 2 C-bus slave address of the PCA9634 is shown in Figure 5 . To conserve power, no
internal pull-up resistors are incorporated on the hardware selectable address pins and
they must be pulled HIGH or LOW.
Remark: Using reserved I 2 C-bus addresses will interfere with other devices, but only if the
devices are on the bus and/or the bus will be open to other I 2 C-bus systems at some later
date. In a closed system where the designer controls the address assignment these
addresses can be used since the PCA9634 treats them like any other address. The
LED All Call, Software Rest and PCA9564 or PCA9665 slave address (if on the bus) can
never be used for individual device addresses.

Slave address
The last bit of the address byte de?nes the operation to be performed. When set to logic 1
a read is selected, while a logic 0 selects a write operation.
