General Description
The EM78P567/P566/P565 is an 8-bit RISC type microprocessor with low power, high speed CMOS technology. There are 16K x 13 / 8K x 13 / 4K x 13 bits Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides Security bits and some One time programmable Option bits to protect the OTP memory code from any external access as well as to meet user’s options.The EM78P567/P566/P565 is integrated onto a single chip are on-chip watchdog (WDT), RAM, A/D, D/A, tone generator, programmable real time clock/counter, internal interrupt, power down mode and tri-state I/O.
