■ DESCRIPTION
The E0C6S48 is a single-chip microcomputer made up of the 4-bit core CPU E0C6200, ROM, RAM, dot matrix
LCD driver, input ports, output ports, I/O ports, clock timer, stopwatch timer, programmable timer, clock-syn-
chronized serial interface, sound generator and watchdog timer. The E0C6S48 is most suitable for applications
with equipment dot matrix display functions such as a highly functional electronic notebook.
