GMS81508B/16B/24B
GMS82512/16/24
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH A/D CONVERTER
1. OVERVIEW
1.1 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 micro-
controllers 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.
The GMS815xxB is functionally 100% compatible with earier GMS81508/16 or GMS81508A/16A, and has better charac-
teristics such as strong EMS, wide operating voltage, temperature, frequency and fast programming time for the OTP.
