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. Important CPU features include:
— Efficient register-oriented architecture
— Selectable CPU clock sources
— Idle and Stop power-down mode release by interrupt
— 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 six CPU clocks) can be assigned to
specific interrupt levels.
S3C80F7/C80F9/C80G7/C80G9 Microcontroller
The S3C80F7/C80F9/C80G7/C80G9 single-chip CMOS microcontroller is fabricated using a highly advanced
CMOS process and is based on Samsung's newest CPU architecture.
The S3C80F9/C80G9 is the microcontroller which has 32-Kbyte mask-programmable ROM and S3C80F7/C80G7
is the microcontroller which has 24-Kbyte mask-programmable ROM.
The S3P80F9/P80G9 is the microcontroller which has 32-Kbyte one-time-programmable EPROM and
S3P80F7/P80G7 is the microcontroller which has 24-Kbyte one-time-programmable EPROM.
Using a proven modular design approach, Samsung engineers developed S3C80F7/C80F9/C80G7/C80G9 by
integrating the following peripheral modules with the powerful SAM87 RC core:
— Internal LVD circuit and 16 bit-programmable pins for external interrupts.
— One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
— One 8-bit timer/counter and one 16-bit timer/counter with selectable operating modes.
— One 8-bit counter with auto-reload function and one-shot or repeat control.
The S3C80F7/C80F9/C80G7/C80G9 is a versatile general-purpose microcontroller which is especially suitable
for use as remote transmitter controller. It is currently available in a 32-pin SOP, 42-pin SDIP and 44-pin QFP
package.
