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.

S3F84UA/F84U8 MICROCONTROLLER
The S3F84UA/F84U8 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process, based on Samsung's newest CPU architecture.
The S3F84UA, S3F84U8 are a microcontroller with a 48K-byte, 8K-byte Flash ROM embedded respectively.
The S3F84UA is a microcontroller with a 48K-byte Flash ROM embedded.
The S3F84U8 is a microcontroller with a 8K-byte Flash ROM embedded.
Using a proven modular design approach, Samsung engineers have successfully developed the S3F84UA/F84U8 by integrating the following peripheral modules with the powerful SAM8 core:

• Five programmable I/O ports, including four 8-bit ports, and one 4-bit port, for a total of 36 pins
• Eight bit-programmable pins for external interrupts
• One 8-bit basic timer for oscillation stabilization and watchdog functions (system reset)
• Three 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
• Two asynchronous UART modules
• Pattern generation module

They are currently available in 44-pin-QFP and 42-pin-SDIP package.
