CHAPTER 1. Introduction
Chapter 1. Introduction
OUTLINE OF CHARACTERISTICS
The GMS300 series is a family of 4-bit, single chip CMOS microcomputer.
Since it can form a system by one chip, it contributes to cost reduction and higher
efficiency in system.
Characteristics

1024 bytes for GMS30112/120/140
Ø$ Data memory : 32 4 bits
$ 43 types of instruction set
$ 3 levels of subroutine nesting
$ 1 bit output port for a large current (REMOUT signal)
$ Operating frequency : 300KHz to 1MHz
$ Instruction cycle : 12.5usec @480KHz
$ CMOS process (Single 3.0V power supply)
$ Stop mode (Through internal instruction)
$ Released stop mode by key input (Masked option)
$ Built in capacitor for ceramic oscillation circuit (Masked option)
$ Built in a watch dog timer (WDT)
$ Low operating voltage : (2.0~4.0V)
