SAM88RCRI MICROCONTROLLERS
Samsung's SAM88RCRI series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various programmable ROM sizes. Important CPU features include:

• Efficient register-oriented architecture
• Selectable CPU clock sources
• Idle and Stop power-down mode released by interrupt
• Built-in basic timer with watchdog function

A address/data bus architecture and a large number of bit-configurable I/O ports provide a flexible programming environment for applications with varied memory and I/O requirements. Timer/counters with selectable operating modes are included to support real-time operations.

S3F94C4 MICROCONTROLLER
The S3F94C4 single-chip 8-bit microcontroller is designed for useful A/D converter application field. The S3F94C4 single-chip CMOS micro-controller is fabricated using a highly advanced CMOS process and is based on Samsung's powerful SAM88RCRI CPU architecture. Stop and idle (power-down) modes were implemented to reduce power consumption.
The S3F94C4 is a micro-controller with a 4-Kbyte multi-time-programmable Full Flash ROM embedded.
The S3F94C4 is a versatile general-purpose microcontrollers that is ideal for use in a wide range of electronics applications requiring simple timer/counter, PWM. In addition, the S3F94C4 advanced CMOS technology provides for low power consumption and wide operating voltage range.
Using the SAM88RCRI design approach, the following peripherals were integrated with the powerful core:

• Three configurable I/O ports (18 pins)
• Four interrupt sources with One vectors and one interrupt level
• 0ne 8-bit timer/counter with time interval modes.
• Analog to digital converter with nine input channels (MAX) and 10-bit resolution
• One PWM output with three optional mode: 8-bit (6+2); 12-bit(6+6); 14-bit(8+6);

The S3F94C4 microcontroller is ideal for use in a wide range of electronic applications requiring simple timer/counter, PWM, ADC. They are currently available in 20 DIP Package, 20/16-pin SOP Package, 20 SSOP Package and 16 TSSOP Package.
