Product Overview Address Spaces Addressing Modes Control Registers Interrupt Structure SAM88RCRI Instruction Set

Samsung's SAM88RCRI family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various mask-programmable ROM sizes. A dual address/data bus architecture and a large number of bit- or nibble-configurable I/O ports provide a flexible programming environment for applications with varied memory and I/O requirements. Timer/counters with selectable operating modes are included to support real-time operations. Many SAM88RCRI microcontrollers have an external interface that provides access to external memory and other peripheral devices.

The S3C9674/C9678/P9678 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM88RCRI CPU core. Stop and Idle power-down modes were implemented to reduce power consumption. To increase on-chip register space, the size of the internal register file was logically expanded. The S3C9674 has 4 K bytes of program memory on-chip and S3C9678 has 8 K bytes. Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core: Five configurable I/O ports (32 pins) 20 bit-programmable pins for external interrupts 8-bit timer/counter with three operating modes Low speed USB function The is a versatile microcontroller that can be used in a wide range of low speed USB support general purpose applications. It is especially suitable for use as a keyboard controller and is available a 42-pin SDIP and a 44-pin QFP package.

The S3C9674/C9678 microcontroller is also available in OTP (One Time Programmable) version, S3P9678. S3P9678 microcontroller has an on-chip 8-Kbyte one-time-programmable EPROM instead of masked ROM. The S3P9678 is comparable to S3C9674/C9678, both in function and in pin configuration.
