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 interrupts
- 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.

S3C828BX/F828BX/C8289X/F8289X/C8285X/F8285X MICROCONTROLLER
The S3C828BX/F828BX/C8289X/F8289X/C8285X/F8285X single-chip CMOS microcontroller are fabricated using the highly advanced CMOS process, based on Samsung's newest CPU architecture.

The S3C828BX, S3C8289X, S3C8285X are a microcontroller with a 64K-byte, 32K-byte, 16K-byte mask-programmable ROM embedded respectively.

The S3F828BX is a microcontroller with a 64K-byte Flash ROM embedded.
The S3F8289X is a microcontroller with a 32K-byte Flash ROM embedded.
The S3F8285X is a microcontroller with a 16K-byte Flash ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C828BX/F828BX/C8289X/F8289X/C8285X/F8285X by integrating the following peripheral modules with the powerful SAM8 core:

- Nine programmable I/O ports, including six 8-bit ports, and one 7-bit port, one 6-bit port, one 4-bit port, for a total of 65 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.
- LCD Controller/driver
- A/D converter with 8 selectable input pins
- Synchronous SIO modules

The S3C828BX/F828BX/C8289X/F8289X/C8285X/F8285X is versatile microcontroller for camera, LCD and ADC application, etc. They are currently available in 80-pin TQFP and 80-pin QFP package

FLASH
The S3F828BX/F8289X/F8285X are FLASH version of the S3C828BX/C8289X/C8285X microcontroller. The S3F828BX microcontroller has an on-chip FLASH ROM instead of a masked ROM. The S3F828BX/F8289X/F8285X is comparable to the S3C828BX/C8289X/C8285X, both in function and in pin configuration. The S3F828BX only is a full flash. The full flash means that data can be written into the program ROM by an instruction.
