Product Introduction

This LSI is an 8-bit RISC type microprocessor with high speed CMOS technology and low power consumption. Integrated onto a single chip are on chip watchdog timer (WDT), Data  RAM,  ROM,  programmable  real  time  clock  counter,  internal/external  interrupt,  power  down  mode,  LCD  driver,  infrared  transmitter  function,  and  tri-state  I/O.  The  EM78P468N provides multi-protection bits to protect against intrusion of user’s code in the OTP memory and a seven option bits to accommodate user’s requirements. It also provides an especial 13 bits customer ID option.

With its OTP-ROM feature, this LSI offers a convenient way of developing and verifying user’s  programs.  Moreover,  user  developed  code can  be  easily  programmed  with  the  ELAN writer.
