16. OPTIONS LIST
The S1D 12400 series has the following options. Options
are available exclusively for users. Please contact our
Sales Department.
●● The following shows how to define the name of the
product compatible with options:
(4) Power off sequence
Similar to the case of power on sequence, if this IC
power is turned off when the built-in power is on,
power supply to the built-in liquid crystal drive
circuit may continue for a very little time, adversely
affecting the liquid crystal panel display quality. To
prevent this, strictly follow the power off sequence.

Character Generator ROM (CGROM)
Specifications
The S1D12400 series is provided with a character
generator ROM for up to 544 types of characters. Each
character size is of a structure of 5 × 7 (8) dots.
This CGROM is designed as a masked ROM, and is
compatible with the CGROM for exclusive use of the
user. For the standard CGROM, see the Character
Font Table.
TCP Specifications
The S1D12400 series is compatible with the TCP
specifications exclusive to the user, in addition to our
standard TCP. Please contact our Sales Department for
information.
Note: This IC is configured as a logic circuit with a
power supply of V
DD–VSS which controls the
LCD power supply V
DD–V5 driver. Therefore,
if the power supply V
DD–VSS is shut down while
voltage remains in the LCD power supply V
DD–
V
5, the driver (COM and SEG) may output an
uncontrolled voltage. When shutting the power
off, be sure to observe the following operation
procedure.
• Turn the internal power supply off, confirm
that the voltage levels of the internal voltage
follower outputs V
1, V2, V3 and V4 have
dropped below the LCD panel threshold
voltage values, then turn the power of this IC
(V
DD–VSS) off.
