KS57C0301/0302 MICROCONTOLLER PRODUCT OVERVIEW
1 PRODUCT OVERVIEW
OVERVIEW
The KS57C0301/0302 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 KS57C0301/0302 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 KS57C0301/0302'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.
