CHAPTER 1. Introduction

Chapter 1. Introduction

OUTLINE OF CHARACTERISTICS

The GMS340 series are remote control transmitter which uses CMOS technology,

and the EPROM version of GMS34XXX series.

This enables transmission code outputs of different configurations, multiple custom

code output, and double push key output for easy fabrication.

The GMS340 series are suitable for remote control of TV, VCR, FANS, Air-

conditioners, Audio Equipments, Toys, Games etc.

• Program memory : 512bytes for GMS34004T

1,024 bytes for GMS34112T/140T

• 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~500KHz at KHz version

2.4MHz~4MHz at MHz version

300KHz~4.2MHz at WIDE version

• Instruction cycle : fOSC/6 at KHz and WIDE version
