描述 Description

The ET5041 series are 8-bit RISC type microprocessor with low power, high speed CMOS technology.\r
There are 4k×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.\r
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 WidthModulation), 8-channel 10-bit A/D converter and tri-state I/O.
