GMS81604 / GMS81608
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
OVERVIEW
Description
The GMS81604/08 is a high-performance CMOS 8-bit microcontroller with 4K or 8K bytes of ROM. The device
is one of GMS800 family. The LG Semicon GMS81604/08 is a powerful microcontroller which provides a highly
flexible and cost effective solution to many embedded control applications. The GMS81604/08 provides the
following standard features: 8K bytes of ROM, 256 bytes of RAM, 35 I/O lines(33 lines for 40PDIP), 16-bit or
8-bit timer/counter, a precision analog to digital converter, on-chip oscillator and clock circuitry. In addition, the
GMS81604/08 supports power saving modes to reduce power consumption. The Stop Mode saves the RAM
contents but freezes the oscillator disabling all other chip functions until the next hardware reset or external
interrupt.

Development Tools
The GMS800 family is supported by a full-featured
macro assembler, an in-circuit emulators CHOICE-
Jr.TM, socket adapters for OTP device.
The availability of OTP devices are especially useful
for customers expecting frequent code changes and
updates. The OTP devices, packaged in plastic pack-
One Buzzer Driving port
31 Programmable I/O, 4 Input pins,
Twelve Interrupt Sources
All LED Direct Drive Output Ports
8-Channel 8-Bit On-Chip Analog to Digital
Converter
Power Fail Processor
(Noise immunity circuit)
Power Down Mode (Stop Mode)
ages permit the user to program them once. In addition
to the program memory, the configuration fuses must
be programmed.
