The S1C6F016 is a 4-bit microcontroller that features low voltage operations and low current consumption. It consists
of a 4-bit core CPU S1C63000 as the core CPU, Flash EEPROM (16,384 words
× 13 bits), RAM (2,048 words × 4
bits), supply voltage detection (SVD) circuit, multiply-divide circuit, serial interface, timers, and sound generator. It
also incorporates a segment LCD controller/driver that can drive a maximum 56-segment
× 8-common LCD panel,
and an R/F converter that can measure temperature and humidity using sensors such as a thermistor.
The S1C6F016 is suitable for battery driven clocks and watches with temperature and humidity measurement func-
tions. The S1C6F016 allows choice from six different models by mask-option selections and shipment form selec-
tions as shown in Table 1.1.
