1OUTLINE
The S1C6S460 is a microcomputer with a C-MOS 4-bit core CPU S1C6200 as main component, and
ROM, RAM, dot matrix LCD driver, time base counter, clock synchronous serial interface, etc. built-in.
Since the S1C6S460 can be driven with low voltage, it is suitable for portable equipment requiring dot
matrix display functions.
The S1C6S460 is a smakker version of the S1C624A0 and except for external memory access function, it
has the same functions as the S1C624A0. Thus it can be used for applications of the S1C624A0 that do dot
need external memory. Note the following structure and characteristics differences between the S1C6S460
and the S1C624A0.
Pad size and layout:
Size 100 m
Pitch 130 m (Min.)
Electrical characteristics:
External resistor value for CR oscillation (built-in capacitor is modified)
CR and ceramic oscillation start times
Low-level output current from output ports
Refer to Chapter 14, "Electrical Characteristics".
