　　单片机低成本解密方案开发与疑难型IC芯片解密方案开发是世纪芯芯片解密研究所长期以来形成的两大重点科研项目，目前，我们在两大研究领域均有突破性进展，能够为广大客户提供最具可靠性和经济价值的解密服务。
　　EM78P156N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology.. It is equipped with 1K*13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides three PROTECTION bits to prevent user’s code in the OTP memory from being intruded. 8 OPTION bits are also available to meet user’s requirements.
　　With its OTP-ROM feature, the EM78P156N is able to offer a convenient way of developing and verifying user’s programs. Moreover, user can take advantage of EMC Writer to easily program his development code.
