牌ELAN型号EM78P153S批号11 封装SOP14营销方式现货产品性质热销处理信号数字信号制作工艺半导体集成集成程度中规模 an 8-bit microprocessor with low-power and high-speed CMOS technology. It is equipped with a 1024 x 13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. 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 EM78P153S offers users a convenient way of developing and verifying their programs. Moreover, user developed code can be easily programmed with the ELAN writer.
