2–50 EPSON Rev. 1.4
S1D12200 Series
16. OPTION LIST
S1D12200 Series provides the optional functions as
described in the following. Being adaptable to the
customer’s optional demand, contact the Business
Department of our company when installed.
o
Our product name corresponding to a customer’s
option is defined as shown below:
1. Specification of Character Generator ROM
(CGROM)
S1D12200 Series integrates a character generator
ROM which can generate a maximum of 256 type
characters.
The size of these characters is composed of 5 × 7 (8)
dots.
Being a mask ROM, the S1D12200 Series CGROM
is adaptable to the character generator ROM exclusive
for the customer, too.
For our standard CGROMs, refer to the Character
Fonts Table.
2. Specification of Liquid Crystal Driver Voltage Bias
Value.
S1D12200 Series integrates a liquid crystal diver
voltage generator circuit. Its 5-volt potential is divided
into resistance inside of IC to generate 1-V, 2-V, 3-
V or 4-V potential as required for the liquid crystal
driver.
Further, the 1-V, 2-V, 3-V or 4-Vpotential is converted
into impedance by a voltage follower to be supplied
to the liquid crystal driver circuit.
Either 1/5 or 1/4 bias value can be selected as
demanded by the customer.
Our standard bias value is preset to 1/5.
3. Specification of Reference Voltage of Liquid Crystal
Driver Voltage Regulation Circuit.
S1D12200 Series integrates a voltage regulation
circuit using a booster voltage as its power supply to
generate 5V for the liquid crystal driver via the
voltage regulation circuit.
The voltage regulation circuit integrates a reference
voltage regulator V
REG.
The customer can select a specification of using
either the internal reference voltage or external V
SS
reference voltage.
Our standard specification is preset to the internal
reference voltage.
4. Power Supply to Booster Circuit
S1D12200 Series integrates a booster circuit.
The customer can select a specification of using
either the regulator output V
S1 or VSS as the supply
voltage to the booster circuit.
Our standard specification is preset to the regulator
output V
S1.
5. External Clock Specifications
S1D12200 Series integrates an external clock terminal
and there are two clock specifications, f and 4×f
oscillation.
Either of them can be selected on your request.
The standard external clock specification is set to
f
OSC.
6. Reset Signal Input Polarity Specifications
S1D12200 Series inputs reset signal from the reset
terminal using edge detection and I/F specification
80/68 series can be selected according to this signal
level.
RES input polarity can also be selected on your
request.
is set to the 68 series and to the 80 series as
the standard RES input polarities.
7. Pad Layout Specifications of COMS1 Symbol
Terminal
On S1D12200 Series, pad layout of COMS1 symbol
terminal can be changed. COMS1 pad layout can be
selected on your request.
