S1C63358 TECHNICAL MANUAL EPSON 5
CHAPTER 1: OUTLINE
1.5 Mask Option
Mask options shown below are provided for the S1C63358. Several hardware specifications are prepared
in each mask option, and one of them can be selected according to the application. The function option
generator winfog and the segment option generator winsog, that have been prepared as the development
software tool of S1C63358, are used for this selection. Mask pattern of the IC is finally generated based on
the data created by the winfog and the winsog. Refer to the "S5U1C63000AManual" for the winfog and
the winsog.
<Functions selectable with S1C63358 mask options>
(1) External reset by simultaneous LOW input to the input port (K00–K03)
This function resets the IC when several keys are pressed simultaneously. The mask option is used to
select whether this function is used or not. Further when the function is used, a combination of the
input ports (K00–K03), which are connected to the keys to be pressed simultaneously, can be selected.
Refer to Section 2.2.2, "Simultaneous low input to terminals K00–K03", for details.
(2) Time authorize circuit for the simultaneous LOW input reset function
When using the external reset function (shown in 1 above), using the time authorize circuit or not can
be selected by the mask option. The reset function works only when the input time of simultaneous
LOW is more than the rule time if the time authorize circuit is being used.
Refer to Section 2.2.2, "Simultaneous low input to terminals K00–K03", for details.
(3) Input port pull-up resistor
The mask option is used to select whether the pull-up resistor is supplemented to the input ports or
not. It is possible to select for each bit of the input ports.
Refer to Section 4.5.3, "Mask option", for details.
(4) Output specification of the output port

CHAPTER 2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
The S1C63358 operating power voltage is as follows:
0.9 V to 3.6 V
Note: • When a voltage within 0.9 V to 1.4 V is used as the operating power voltage, software control is
necessary (see Section 4.2).
•When using the A/D converter with 0.9 V to 1.6 V power supply voltage, software control is
necessary.
The S1C63358 operates by applying a single power supply within the above range between VDD/AVDD
and VSS/AVSS. The S1C63358 itself generates the voltage necessary for all the internal circuits by the
built-in power supply circuits shown in Table 2.1.1.

CHAPTER 2: POWER SUPPLY AND INITIAL RESET
2.1.1Voltage <VD1> for oscillation circuit and internal circuits
VD1 is a voltage for the oscillation circuit and the internal logic circuits, and is generated by the oscillation
system voltage regulator for stabilizing the oscillation.
The S1C63358 is designed with twin clock specification; it has two types of oscillation circuits OSC1 and
OSC3 built-in. Use OSC1 clock for normal operation, and switch it to OSC3 by the software when high-
speed operation is necessary. When switching the clock, the operating voltage VD1 must be switched by
the software to stabilize the operation of the oscillation circuit and internal circuits.
The oscillation system voltage regulator can output the following two types of VD1 voltage. It should be
set at the value according to the oscillation circuit and oscillation frequency by the software.
Single clock operation (OSC1 crystal oscillation): VD1 = 1.35 V
Single clock operation (OSC1 CR oscillation): VD1 = 2.25 V
Twin clock operation (OSC3, 4 MHz): VD1 = 2.25 V
Refer to Section 4.4, "Oscillation Circuit", for the VD1 switching procedure.
However, since the VD1 voltage value is fixed at 2.25 V when the CR oscillation circuit has been selected
as the OSC1 oscillation circuit by mask option, it is not necessary to switch VD1 by software.
2.1.2Voltage <VC1–VC3> for LCD driving
VC1 to VC3 are the voltages for LCD drive, and are generated by the LCD system voltage circuit to
stabilize the display quality.
The LCD system voltage circuit generates VC1 with the voltage regulator built-in, and generates two
other voltages by boosting the voltage of VC1 (VC2 = 2•VC1, VC3 = 3•VC1). When 1/2 bias is selected by
mask option, VC2 becomes the same level with VC1. (VC2 = VC1, VC3 = 2•VC1).
1.4 V or more voltage is needed to generate the voltage VC1.
Therefore, when operating with 0.9–1.4 V, the LCD display contrast will become worse.
Refer to Chapter 7, "Electrical Characteristics", for voltage values of VC1 to VC3.
2.1.3Voltage source for oscillation system voltage regulator
(1)Booster mode (VC2 mode)
The S1C63358 operates with 0.9–3.6 V supply voltage. However, a minimum 1.4 V supply voltage
during single clock operation (OSC1) or a minimum 2.3 V during twin clock operation (OSC3, 4 MHz)
is needed for the oscillation system voltage regulator. Therefore, when operating with the following
supply voltage (VDD), switch the power supply source to drive the oscillation system regulated
voltage circuit with the VC2.
• During single clock operation (OSC1): VDD = 0.9–1.4 V (VC2 = 1.8–2.1 V)
When the supply voltage is more than needed for operation, do not set in this mode because the VC2
power source will increases current consumption to the oscillation system voltage regulator.
Note: Set the booster mode when a supply voltage drop is detected by the SVD circuit, such as during
heavy load operation (driving buzzer or lamp) or by battery life. (
∗ )
(2)Normal mode
In this mode, the internal power circuit directly operates by the power supply voltage VDD within the
range of 1.4–3.6 V (2.3–3.6 V when the OSC3 clock is used) without changing the power source (VD1
regulator) to VC2. At initial reset, this mode is set.
When the supply voltage VDD is within the range of 1.4–3.6 V, don't change the power source (VD1
regulator) to VC2 (VDSEL = "1"), otherwise it will cause malfunction.

2.1.4Voltage source for A/D converter
(1)Booster mode (VC2 mode)
The A/D converter operates with 0.9–3.6 V supply voltage. However, a minimum 1.6 V supply
voltage is need for the A/D converter maximum error within ±5 LSB. Therefore, when operating with
a 1.6 V or less of supply voltage (VDD), switch the power supply source to drive the A/D converter
circuit with the VC2.
(2)Normal mode
In this mode, the A/D converter circuit directly operates by the power supply voltage VDD above 1.6
V without changing the power source to VC2.
