Description

The S3C8274 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process, based on Samsung's latest CPU architecture.

The S3C8274 is a microcontroller with a 16/8/4K-byte mask-programmable ROM embedded.
The S3C8274 is a microcontroller with a 16/8/4K-byte flash ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C8274 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
