General Description
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.
