Description
The EM78P142SS10J is an 8-bit microprocessor designed with low-power and high-speed CMOS technology. It features an on-chip 2K×13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM) with a protection bit to prevent intrusion of user's OTP memory code. The EM78P142SS10J also offers three code option bits to meet user's requirements. With enhanced OTP-ROM features, it provides a convenient and effective way of developing and verifying user's programs. This model can be easily programmed using the ELAN Writer.
