1.1 S3C8-Series Microcontrollers

Zilog'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.

1.2 S3F8S6B Microcontroller

The S3F8S6B single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process, based

on Zilog's newest CPU architecture.

The S3F8S6B is a microcontroller with a 64KB Flash ROM embedded respectively.

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

S3F8S6B by integrating the following peripheral modules with the powerful SAM8 core:

? Seven programmable I/O ports, including six 8-bit ports, and one 6-bit port, for a total of 54 pins

? Sixteen 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 64-pin QFP and 64-pin SDIP package
