1 PRODUCT OVERVIEW
S3C8-SERIES MICROCONTROLLERS
Samsung's S3C8-series 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. The major CPU features are:
— Efficient register-oriented architecture
— Selectable CPU clock sources
— Idle and Stop power-down mode released by interrupt or reset
— Built-in basic timer with watchdog function
A 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 of four CPU clocks) can be assigned to
specific interrupt levels.
S3C84E5/C84E9/P84E9 MICROCONTROLLER
The S3C84E5/C84E9/P84E9 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS
process technology based on Samsung’s latest CPU architecture.
The S3C84E5 is a microcontroller with a 16K-byte mask-programmable ROM embedded.
The S3C84E9 is a microcontroller with a 32K-byte mask-programmable ROM embedded.
The S3P84E9 is a microcontroller with a 32K-byte OTP ROM embedded.
Using a proven modular design approach, Samsung engineers have successfully developed the
S3C84E5/C84E9/P84E9 by integrating the following peripheral modules with the powerful SAM8 core:
— Five programmable I/O ports (42SDIP: 34pins, 44QFP: 36pins)
— Eleven bit-programmable pins for external interrupts.
— One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
— Two 8-bit timer/counter and Two 16-bit timer/counter with selectable operating modes.
— One asynchronous UART
— 10-bit 8-channel A/D converter
The S3C84E5/C84E9/P84E9 is versatile microcontroller for home appliances and ADC applications, etc. They are
currently available in 44-pin QFP and 42-pin SDIP package.
