CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
OVERVIEW
Description
The GMS81504 is a high-performance CMOS 8-bit microcontroller with 4K bytes of ROM. The device is one
of GMS800 family. The HYUNDAI GMS81504 is a powerful microcontroller which provides a highly flexible
and cost effective solution to many embedded control applications. The GMS81504 provides the following
standard features: 4K bytes of ROM, 128 bytes of RAM, 23 I/O lines(21 lines for 28SOP), 16-bit or 8-bit
timer/counter, a precision analog to digital converter, on-chip oscillator and clock circuitry. In addition, the
GMS81504 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-
ages permit the user to program them once. In addition
to the program memory, the configuration fuses must
be programmed.
