Description
The EM78P5841NPJ is an 8-bit RISC architecture microcontroller device designed with low-power, high-speed CMOS technology. It features on-chip 4K×13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM) that provides a protection bit to prevent intrusion of user's OTP memory code and unwanted external accesses. This model also offers a number of one-time programmable option bits to meet various application requirements.
