The EM78P507N is an 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology. Integrated onto a single IC are on-chip Watchdog Timer (WDT), RAM, ROM, programmable real time clock counter (TCC), internal/external interrupt, power down mode, four 8-bit timers, SPI, I2C, UART, Current type DA Converter,10 bits/24 channels AD , LVD, and tri-state I/O. It is equipped with a 6K×13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). With its enhanced OTP-ROM features, the EM78P507N provides a convenient way of developing and verifying user’s programs. Moreover, this OTP-ROM device offers the advantages of easy and effective program updates, using development and programming tools. Users can avail of the ELAN Writer to easily program their development codes.
