PRODUCT OVERVIEW
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.

S3P8454 OTP
OVERVIEW
The S3P8454 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the S3C8454
microcontrollers. It has an on-chip EPROM instead of masked ROM. The EPROM is accessed by serial data
format.
S3P8454 is fully compatible with S3C8454, both in function and in pin configuration. As it has simple
programming requirements, S3P8454 is ideal for use as an evaluation chip for the S3C8454.
