General Description

The EM78P259N is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 2Kx13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a protection bit to prevent intrusion of user's code. Three Code option words are also available to meet user's requirements.
With its enhanced OTP-ROM feature, the EM78P259N provides a convenient way of developing and verifying user's programs. Moreover, this OTP device offers the advantages of easy and effective program updates, using development and programming tools. User can avail of the ELAN Writer to easily program his development code.

Internal RC Frequency	Drift Rate
Internal RC Frequency	Temperature(-40°C ~80°C )	Voltage(2.3V~5.5V)	Process	Total
4MHz	±10%	±5%	±4%	±19%
8MHz	±10%	±6%	±4%	±20%
1MHz	±10%	±5%	±4%	±19%
