EM78862K数据手册Elan中文资料规格书

描述 Description

The EM78862K is an 8-bit RISC type microprocessor with low power, high speed CMOS technology. Integrated into the single chip are on-chip watchdog (WDT), RAM, ROM, programmable real-time clock/counter, internal interrupt, power-down mode, LCD driver, and tri-state I/O. The EM78862K provides a single chip solution for designing DATA-BANK of message display. Please note that operating temperature range of chip is 0 to 70 degree.
