PRODUCT OVERVIEW  
SAM87 RC PRODUCT FAMILY  
Samsung's new SAM87RC 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 SAM87RC 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.  
S3C8454 MICROCONTROLLER  
The S3C8454 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is  
based on the powerful SAM87RC 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 1040 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of  
program and data memory. The S3C8454 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 SAM87RC modular design approach, the following peripherals were integrated with the SAM87RC  
CPU core:  
— Five configurable 8-bit general I/O ports  
— One 2-bit general I/O ports  
— Full-duplex serial data port with one synchronous operating modes  
— Two 8-bit timers with interval timer  
— Two 16-bit timers/counters with PWM operating modes or capture modes  
— One voltage level detector pin  
— Four embedded chip selection pins (CS0–CS4) or normal I/O ports  
— Two programmable 8-bit PWM modules with corresponding output pins  
— A/D converter with 4 selectable input pins  
OTP  
The S3C8454 microcontroller is also available in OTP(One Time Programmable) version, S3P8454  
The S3P8454 microcontroller has an on-chip 4K-byte one-time-programmable EPROM instead of masked ROM.  
The S3P8454 is comparable to S3C8454, both in function and in pin configuration.
