Automotive 80 × 4 LCD driver for low multiplex rates
The command bytes and control bytes are also acknowledged by all addressed
PCA85233 connected to the bus.
The display bytes are stored in the display RAM at the address specified by the data
pointer and the subaddress counter. Both data pointer and subaddress counter are
automatically updated.
The acknowledgement after each byte is made only by the (A0 and A1) addressed
PCA85233. After the last display byte, the I
2
C-bus master issues a STOP condition (P).
Alternatively a START may be asserted to RESTART an I
2
C-bus access.

10. Safety notes
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Observe precautions for handling
electrostatic sensitive devices.
Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A or
equivalent standards.
CAUTION
Static voltages across the liquid crystal display can build up when the LCD supply voltage
(V
LCD
) is on while the IC supply voltage (V
DD
) is off, or vice versa. This may cause unwanted
display artifacts. To avoid such artifacts, V
LCD
and V
DD
must be applied or removed together.
CAUTION
Semiconductors are light sensitive. Exposure to light sources can cause the IC to
malfunction. The IC must be protected against light. The protection must be applied to all
sides of the IC.
