EM78F662N中文资料F66x series(Win™)Flash ADC Type with EEPROM (Industrial Grade)数据手册Elan规格书

描述 Description

The EM78F662N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology and
high noise immunity. It has an on-chip 2K⊙13-bit Electrical Flash Memory and 128⊙8-bit in system programmable
EEPROM. It provides three protection bits to prevent intrusion of user's Flash memory code. Twelve Code option bits are
also available to meet user's requirements.
With its enhanced Flash-ROM features, the EM78F662N provides a convenient way of developing and verifying user's
programs. Moreover, this Flash-ROM device offers the advantage of easy and effective program updates, using
development and programming tools. User can avail of the ELAN Writer to easily program his development code.
