Specification

Overview

  • General Description

    The EM88F758N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology and high noise immunity. It has an on-chip 8K-16-bit Electrical Flash Memory and 256 bytes In-system programmable EEPROM. The debug function is built in the EM88F758N chip. User can read the program code from JTAG port and monitor the on-chip register status, memory and program trace log on computer. Using OCDS, user can develop their program for several ELAN flash types IC.
