DESCRIPTION
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 µA at standby
mode). The S1C88848 also contains the SVD circuit for detecting drop of battery voltage, and is most suitable
for remote controllers for home electric appliances.
