Description

The GMS81508B/16B/24B are advanced CMOS 8-bit microcontrollers with 8K/16K/24K bytes of ROM. The device is one of GMS800 family. GMS81508B/16B/24B using the GMS800 family CPU includes several peripheral functions such as Timer, A/D converter, Programmable buzzer driver, Serial I/O communication, Pulse Width Modulation function, etc. The RAM, ROM, and I/O are placed on the same memory map in addition to simple instruction set.

The GMS815xxB is functionally 100% compatible with earier GMS81508/16 or GMS81508A/16A, however better characteristics have such as strong EMS, wide operating voltage, temperature, frequency and fast programming time for the OTP.
