S3C7031 Datasheet | Samsung Semiconductor

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 parator 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 plete 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 patibility. 1-1 PRODUCT OVERVIEW S3C7031/7032 FEATURES Memory - 1024 × 8-bit program memory (S3C7031) (ROM) - 2048 × 8-bit program memory (S3C7032) (ROM) - 128 × 4-bit data memory (S3C7031) (RAM) - 256 × 4-bit data memory (S3C7032) (RAM) I/O Pins - Up to 15 pins for 20-DIP and 20-SOP package parator Inputs - 4-channel mode Internal reference: 4-bit resolution - 3-channel mode External reference 8-Bit Basic Timer - Programmable interval timer 8-Bit Timer/Counter - Programmable interval timer - External event counter function -...
