Description

The S3C820B single-chip CMOS microcontroller is fabricated using a highly advanced CMOS process and is based on Samsung's newest CPU architecture.

The S3C820B is the microcontroller which has 64K-byte mask-programmable ROM and 192K-byte mask ROM for font data.

Using a proven modular design approach, Samsung engineers developed the S3C820B by integrating the following peripheral modules with the powerful SAM87 core:

  - Four programmable I/O ports, excluding one BUZ pin, for a total of 32 pins.
  - Eight bit-programmable pins for external interrupts.
  - One 8-bit basic timer for oscillation stabilization and watchdog functions (system reset).
  - One 8-bit timer/counter and one 16-bit timer/counter with selectable operating modes.
  - Watch timer for real time.

The S3C820B is a versatile microcontroller for data bank or dictionary. It is currently available in a 128- pin QFP package.
