Description

The S3C8249 single-chip CMOS microcontroller are fabricated
using the highly advanced CMOS process, based on Samsung's newest CPU architecture.

The S3C8248, S3C8245, S3C8247, S3C8249 are a microcontroller with a 8K-byte, 16K-byte, 24K-byte.
32K-byte mask-programmable ROM embedded respectively.

The S3P8245 is a microcontroller with a 16K-byte one-time-programmable ROM embedded.
The S3P8249 is a microcontroller with a 32K-byte one-time-programmable ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C8249 by integrating the following peripheral modules with the
powerful SAM8 core:

  - Six programmable I/O ports, including five 8-bit ports and one 5-bit port, for a total of 45 pins.
  - Eight bit-programmable pins for external interrupts.
  - One 8-bit basic timer for oscillation stabilization and watchdog functions (system reset).
  - Two 8-bit timer/counter and two 16-bit timer/counter with selectable operating modes.
  - Watch timer for real time.
  - 8-input A/D converter
  - Serial I/O interface

The S3C8249 is versatile microcontroller for camera, LCD and
ADC application, etc. They are currently available in 80-pin TQFP and 80-pin QFP package
