Functions
Description
Equivalent Circuit
26
STBY
Controls the running/stopped state of this IC.
When low, only VDD5V operates. All other circuits are
stopped.
When high, only COM10V and VDD5V operate
unconditionally. All other outputs are controlled by the serial
data.
28
VDD 5V
When +B is applied to the VCC2 pin, 5V is output.
Used as the power supply system for systems, such as the
microcontroller, that require memory backup.
IQ = 150 to 180μA
The current flowing into pin 28 when VCC is off, is minimal.
