下面是关于EM78P153E芯片的主要性能特征介绍,我们提供给广大客户及其他各类技术工程师参考借鉴。
EM78P153E is an 8-bit microprocessor with low-power and high-speed CMOS technology. It is equipped with a 512*13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a PROTECTION bit to prevent intrusion of user’s code in the OTP memory as well as 15 OPTION bits to match user’s requirements.
  With its OTP-ROM feature, the EM78P153E offers users a convenient way of developing and verifying their programs. Moreover, user developed code can be easily programmed with the EMC writer.
