After an acknowledgement, one or more command bytes follow that define the status of
each addressed PCA85162.
The last command byte sent is identified by resetting its most significant bit, continuation
bit C (see Figure 21
). The command bytes are also acknowledged by all addressed
PCA85162 on the bus.
After the last command byte, one or more display data bytes may follow. Display data
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
and the data directed to the intended PCA85162 device.
An acknowledgement after each byte is asserted only by the PCA85162 that are
addressed via address lines A0, A1, and A2. After the last display byte, the I
2
C-bus
master asserts a STOP condition (P). Alternately a START may be asserted to restart an
I
2
C-bus access.

10. Safety notes
11. Limiting values
[1] Pass level; Human Body Model (HBM), according to Ref. 8 “JESD22-A114.
[2] Pass level; Charged-Device Model (CDM), according to Ref. 9 “
JESD22-C101.
[3] Pass level; latch-up testing according to Ref. 10 “
JESD78 at maximum ambient temperature (T
amb(max)
).
[4] According to the store and transport requirements (see Ref. 14 “
UM10569) the devices have to be stored at a temperature of +8 C to
+45 C and a humidity of 25 % to 75 %.
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.
Table 18. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
