描述 Description

The GMS81508B/16B/24B are advanced CMOS 8-bit microcontrollers with 8K/16K/24K bytes of ROM and 64pin package. And the GMS82512/16/24 are the same except for 12K/16K/24K bytes of ROM and 42pin package. The GMS825xx is a cut-down product of GMS815xxB microcontroller, that is, the function and package are reduced. These are powerful microcontrollers which provide a highly flexible and cost effective solution to many general application. These includes several peripheral functions such as Timer, A/D converter, Programmable buzzer driver, Serial I/O communication(GMS815xxB only), Pulse Width Modulation function( GMS815xxB only), etc. The RAM, ROM, and I/O are placed on the same memory map in addition to simple instruction set. Also, they support power saving mode to reduce power consumption.
