产品说明 
General Description 

The EM78P809N is an 8-bit microprocessor with low-power, high-speed CMOS technology and high noise immunity. It has a built-in 8K x 13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides multi-protection bits to prevent intrusion of user's OTP memory codes. Seven Option bits are also available to meet user's requirements. 

With its OTPROM feature, the EM78P809N is able to offer a convenient way of developing and verifying user's programs. Moreover, user can take advantage of ELAN Writer to easily program his development code.
