Overview: S3C9004/P9004/C9014/P9014 PRODUCT OVERVIEW 1 PRODUCT OVERVIEW SAM87RI PRODUCT FAMILY
Samsung's SAM87RI 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 SAM87RI microcontrollers have an external interface that provides access to external memory and other peripheral devices. S3C9004/P9004/C9014/P9014 MICROCONTROLLER
The S3C9004/P9004/C9014/P9014 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM87RI 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 S3C9004/P9004/C9014/P9014 has 4 K bytes of program memory on-chip. Using the SAM87RI design approach, the following peripherals were integrated with the SAM87RI core: — Five configurable I/O ports (32 pins) — 12 bit-programmable pins for external interrupts — 8-bit timer/counter with three operating modes The S3C9004/P9004/C9014/P9014 is a versatile microcontroller that can be used in a wide range of general purpose applications. It is especially suitable for use as a keyboard controller and is available in a 40-pin DIP and a 44-pin QFP package. OTP
The S3C9004/C9014 microcontroller is also available in OTP (One Time Programmable) version, S3P9004/P9014. S3P9004/P9014 microcontroller has an on-chip 8-Kbyte one-time-programmable EPROM instead of masked ROM. The S3P9004/P9014 is comparable to S3C9004/C9014, both in function and in pin configuration.
