8.4 I 2 C-bus controller
The PCA85132 acts as an I 2 C-bus slave receiver. It does not initiate I 2 C-bus transfers or
transmit data to an I 2 C-bus master receiver. The only data output from the PCA85132 is
the acknowledge signal. Device selection depends on the I 2 C-bus slave address, on the
transferred command data, and on the hardware subaddress.
In single device applications, the hardware subaddress inputs A0 and A1 are normally tied
to V SS which defines the hardware subaddress 0. In multiple device applications
A0 and A1 are tied to V SS or V DD in accordance with a binary coding scheme. No two
devices with a common I 2 C-bus slave address must have the same hardware
subaddress.
8.5 Input filters
To enhance noise immunity in electrical adverse environments, RC low-pass filters are
provided on the SDA and SCL lines.
8.6 I 2 C-bus protocol
Two I 2 C-bus slave addresses (0111 000 and 0111 001) are reserved for the PCA85132.
The entire I 2 C-bus slave address byte is shown in Table 18 .

The PCA85132 is a write-only device and does not respond to a read access, therefore
bit 0 should always be logic 0. Bit 1 of the slave address byte, that a PCA85132 responds
to, is defined by the level tied to its SA0 input (V SS for logic 0 and V DD for logic 1).
