EM78P5840/5841/5842
8-bit Micro-controller
I. General Description
The EM78P5840 series are 8-bit RISC type microprocessor with low power, high speed CMOS technology. There
are 4Kx13 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.
This integrated single chip has an on_chip watchdog timer (WDT), program OTP-ROM, RAM, programmable real
time clock/counter, internal interrupt, power down mode, dual PWM (Pulse Width Modulation), 8-channel 10-bit A/D
converter and tri-state I/O.
