S3C9-SERIES MICROCONTROLLERS
Samsung's SAM88RCRI family 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.

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.

S3C9484/C9488/F9488 MICROCONTROLLER
The S3C9484/C9488/F9488 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process technology based on Samsung’s latest CPU architecture.

The S3C9484 is a microcontroller with a 4K-byte mask-programmable ROM embedded.
The S3C9488 is a microcontroller with a 8K-byte mask-programmable ROM embedded.
The S3F9488 is a microcontroller with a 8K-byte multi time programmable ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C9484/C9488/F9488 by integrating the following peripheral modules with the powerful SAM88 RCRI core:

- Five configurable I/O ports (38 pins) with 8-pin LED direct drive and LCD display
- Ten interrupt sources with one vector and one interrupt level
- One watchdog timer function with two source clock (Basic Timer overflow and internal RC oscillator)
- One 8-bit basic timer for oscillation stabilization
- Watch timer for real time clock
- Two 8-bit timer/counter with time interval, PWM, and Capture mode
- Analog to digital converter with 9 input channels and 10-bit resolution
- One asynchronous UART

The S3C9484/C9488/F9488 microcontroller is ideal for use in a wide range of home applications requiring simple timer/counter, ADC, LED or LCD display with ADC application, etc. They are currently available in 32-pin SOP/SDIP, 42-pin SDIP and 44-pin QFP package.

MTP
The S3F9488 has on-chip 8-Kbyte multi time programmable (MTP) ROM instead of masked ROM. The S3F9488 is fully compatible to the S3C9488, in function, in D.C. electrical characteristics and in pin configuration.
