EM78P142中文资料OTP ADC Type MCU Series (High EFT/ESD Level)数据手册Elan规格书

描述 Description

The EM78P142 is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 2Kx13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a protection bit to prevent intrusion of user's OTP memory code. Three Code option bits are also available to meet user's requirements.

With enhanced OTP-ROM features, the EM78P142 provides a convenient way of developing and verifying user's programs. Moreover, this OTP device offers the advantages of easy and effective program updates, using development and programming tools. User can avail of the ELAN Writer to easily program his development code.
