Specification

Overview

  • General Description

    The EM78P159N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology. It is quipped with 1k x 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. Eight OPTION bits are also available to meet user's requirements. With its OTP-ROM feature, the EM78P159N is able to offer a convenient way of developing and verifying user's programs. Moreover, user can take advantage of the ELAN Writer to easily program his development code.

  • Features & Benefits

      • Operating voltage range: 2.1V~5.5V at 0°C~70°C (Commercial Grade), 2.3V~5.5V at -40°C~85°C (Industrial Grade)
      • Crystal mode: DC~20MHz at 5.0V, DC~8MHz at 3.0V, DC~4MHz at 2.1V
