The S3C9454B/F9454B single-chip 8-bit microcontroller is designed for useful A/D converter application field. The S3C9454B/F9454B uses powerful SAM88RCRI CPU and S3C9454B/F9454B architecture. The internal register file is logically expanded to increase the on-chip register space.

The S3C9454B/F9454B has 4K bytes of on-chip program ROM and 208 bytes of RAM. The S3C9454B/F9454B is a versatile general-purpose microcontroller that is ideal for use in a wide range of electronics applications requiring simple timer/counter, PWM. In addition, the S3C9454B/F9454’s 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 SAM88RCRI core:

— Three configurable I/O ports (18 pins)
— Four interrupt sources with one vector and one interrupt level
— One 8-bit timer/counter with time interval mode
— Analog to digital converte
