EM78247B/447B
8-BIT MICRO-CONTROLLER FOR GENERAL PURPOSE PRODUCT
9.30.1997
GENERAL DESCRIPTION
The EM78247B/447B is an 8-bit microprocessor with low-power, high speed CMOS technology.
Integrated onto a single chip are on-chip watchdog timer (WDT), RAM, ROM, programmable real time clock/
counter, power down mode and bi-directional tri-state I/O ports. It can be developed as cordless phone or other
applications.
