PRODUCT OVERVIEW
SAM88RCRI PRODUCT FAMILY
Samsung's SAM88RCRI family of 8-bit single-chip
CMOS microcontrollers offer fast and efficient CPU, a wide range of integrated peripherals, and supports OTP device. A dual address/data bus architecture and 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.
S3C9234/P9234 MICROCONTROLLER
The S3C9234 can be used for dedicated control functions in a variety of applications, and is especially designed for application with FRS or etc. The S3C9234/P9234 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 S3C9234/P9234 has 4K-byte of program ROM, and 208-byte of RAM (including 16-byte of working register and 16-byte LCD display RAM). Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core: — 7 configurable I/O ports including ports shared with segment/common drive outputs — 7-bit programmable pins for external interrupts — One 8-bit ...
