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. Among the major CPU features are:
• Efficient register-oriented architecture
• Selectable CPU clock sources
• Idle and Stop power-down mode release 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.
S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X MICROCONTROLLER
The S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X single-chip CMOS microcontrollers are fabricated
using the highly advanced CMOS process, based on Samsung's latest CPU architecture.
The S3C8275X/C8278X/C8274X is a microcontroller with a 16/8/4K-byte mask-programmable ROM embedded.
The S3F8275X/F8278X/F8274X is a microcontroller with a 16/8/4K-byte flash ROM embedded.
Using a proven modular design approach, Samsung engineers have successfully developed the
S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X by integrating the following peripheral modules with the
powerful SAM8 core:
• Seven programmable I/O ports, including six 8-bit ports and one 4-bit port, for a total of 52 pins.
• Eight bit-programmable pins for external interrupts.
• One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
• Two 8-bit timer/counter with selectable operating modes.
• Watch timer for real time
FLASH
The S3F8275X/F8278X/F8274X are FLASH version of the S3C8275X/C8278X/C8274X microcontroller. The
S3F8275X/F8278X/F8274X microcontroller has an on-chip FLASH ROM instead of a masked ROM. The
S3F8275X/F8278X/F8274X is comparable to the S3C8275X/C8278X/C8274X, both in function and in pin
configuration. The S3F8275X only is a full flash. The full flash means that data can be written into the program
ROM by an instruction.
