1. OVERVIEW
1.1 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. This device 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 charac-
teristics have such as strong EMS, wide operating voltage, temperature, frequency and fast programming time for the OTP.
