DESCRIPTION
The E0C6251 is a single-chip microcomputer made up of the 4-bit core CPU E0C6200A, ROM, RAM, LCD
driver, input ports, output ports, I/O ports, clock timer and A/D converter (R/F conversion type). Because of its
low-voltage operation and low power consumption, this series is ideal for a wide range of applications, and is
especially suitable for battery-driven systems.
