1 INTRODUCTION
1 INTRODUCTION
The S1C88848 microcomputer features the
S1C88 (Model 3) CMOS 8-bit core CPU along with
ROM, RAM, a remote-control carrier output, a dot-
matrix LCD controller/driver that allows driving of
up to 1,632 pixels, three different timers and a serial
interface with optional asynchronization or clock
synchronization.
The S1C88848 is fully operable over a wide range of
voltages, and can perform stable operations even at
low voltage (1.8 V Min.). Like all the devices in the
S1C Family, this microcomputer has low current
consumption (1.7 A at standby mode)4.
The S1C88848 also contains the SVD circuit for
detecting drop of battery voltage, and is most
suitable for remote controllers for home electric
appliances.

3 A supply voltage of less than 2.4 V affects the LCD contrast.
4 After an initial reset, both OSC1 and OSC3 go ON and the CPU starts operating with the OSC3 clock. Furthermore, the remote controller
operates with the OSC3 clock regardless of whether the REM output option is selected or not. When the remote controller is not used,
it should be turned OFF in the initial routine that will be executed after an initial reset to reduce current consumption.
