S3C9428

S3C9424/C9428/P9428 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 address/data bus architecture and a large number of bit-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. S3C9424/C9428/P9428 MICROCONTROLLER The S3C9424/C9428/P9428 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM87Ri CPU core. The S3C9424/C9428/P9428 is a versatile microcontroller, with its A/D converter, SIO, IIC and a zero-crossing detection capability it can be used in a wide range of general purpose applications. 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 S3C9424/C9428/P9428 have 4K-byte or 8K-byte of program memory on-chip (ROM) and 208-bytes of general purpose register area RAM. Using the SAM87Ri design approach, the following peripherals were integrated with the SAM87Ri core: Four configurable I/O ports (24 pins) Nine interrupt sources with one vector and one interrupt level Two 8-bit timer/counter with various operating modes...
