1 PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVER VIEW
The S3C7031/7032 single-chip CMOS microcontroller has been designed for high performance using Samsung's
newest 4-bit CPU core.
With comparator inputs, high-current LED direct-drive pins, serial I/O interface, and a versatile 8-bit
timer/counter, the S3C7031/7032 offers an excellent design solution for a wide range of applications such as
mouse controllers, subsystem controllers, and toys.
Up to 15 pins of the 20-pin DIP or 20-pin SOP package can be dedicated to I/O. Pull-up resistors are assignable
to all of the pins by software. Four vectored interrupts provide fast response to internal and external events.
In addition, the S3C7031/7032's advanced CMOS technology provides for very low power consumption and a
wide operating voltage range.
DEVELOPMENT SUPPORT
The Samsung Microcontroller Development System, SMDS, provides you with a complete PC-based
development environment for KS57-series microcontrollers that is powerful, reliable, and portable. In addition to
its easy to use window-oriented program development structure, the SMDS toolset includes versatile debugging,
trace, instruction timing, and performance measurement applications.
The Samsung Generalized Assembler (SAMA) has been designed specifically for the SMDS environment and
accepts assembly language sources in a variety of microprocessor formats.
SAMA generates industry-standard object files that also contain program control data for SMDS compatibility.

Description
4-bit I/O port. 1-bit, 4-bit or 8-bit read/write and test is
possible. Pins are individually configurable as input
or output.
Pull-up resistors are individually assignable to input
pins by software and are automatically disabled for
output pins. Ports are software configurable as
n-channel open-drain outputs or push-pull output by
software.
Ports 2 and 3 can be paired to enable 8-bit data
transfer.
Eight frequency outputs
External clock input or timer clock output
External interrupts with rising or falling edge
