■ DESCRIPTION
The E0C6248 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. Moreover, external memory device control is
possible, and is most suitable for applications with equipment requiring large memory and dot matrix display
functions such as a highly functional electronic notebook.
