Description
S3C84A4/P84A4 PRODUCT OVERVIEW 1 PRODUCT OVERVIEW SAM88 RC PRODUCT FAMILY Samsung's new SAM88RC 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. Timer/counters with selectable operating modes are included to support real-time operations. Many SAM88RC microcontrollers have an external interface that provides access to external memory and other peripheral devices. The sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more interrupt sources and vectors. Fast interrupt processing (within a minimum six CPU clocks) can be assigned to specific interrupt levels. S3C84A4X MICROCONTROLLER The S3C84A4 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is based on the powerful SAM88RC CPU core. Stop and Idle power-down modes were implemented to reduce power consumption. The size of the internal register file is logically expanded, increasing the addressable on-chip register space to 784 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of program and data memory. The S3C84A4 is a versatile microcontroller that is ideal for use in a wide range of general-purpose applications such as CD-ROM/DVD-ROM drives. Using the SAM88RC modular design approach, the following peripherals were integrated with the SAM88RC CPU core: — Three configurable 8-bit ...
