5.1 Notes for Low Current Consumption
The S1C63653 contains control registers for each of the circuits so that current consumption can be
reduced.
These control registers reduce the current consumption through programs that operate the circuits at the
minimum levels.
The following lists the circuits that can control operation and their control registers. Refer to these when
programming.
Table 5.1.1 Circuits and control registers
Circuit (and item)
CPU
CPU operating frequency
High-speed operation voltage regulator
LCD system voltage circuit
Voltage halver mode
Control register
HALT instruction
CLKCHG, OSCC
VDC0, VDC1
LPWR
VDC2, VDC3
Refer to Chapter 7, "Electrical Characteristics" for current consumption.
Below are the circuit statuses at initial reset.
CPU
: Operating status
CPU operating frequency
: Low speed side (CLKCHG = "0")
OSC3 oscillation circuit is in off status (OSCC = "0")
Internal logic operating voltage
:VD1L (VDC0 = "0")
High-speed operation voltage regulator
:Off status (VDC1 = "0")
LCD system voltage circuit
:Off status (LPWR = "0")
Voltage halver mode
:Off status (VDC2 = VDC3 = "0")
Also, be careful about panel selection because the current consumption can differ by the order of several
A on account of the LCD panel characteristics.
