S3C94A5/F94A5MICROCONTROLLER

The S3C94A5 can be used for dedicated control functions in a variety of applications, and is especially designed for application with printer or etc. The S3C94A5/F94A5single-chip 8 -bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM88RCRI CPU core. Stop and Idle power-down modes were implemented to reduce power consumption. To increase on-chip register space, the size of the internal register file was logically expanded. The S3C94A5/F94A5has 16K -byte of program ROM, and 368-byte of RAM (including 16-byte of working register).
Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core:

— 5 configurable I/O ports including ports
— 15-bit programmable pins for external interrupts
— One 8-bit basic timer for oscillation stabilization and watch -dog functions
— Two 16-bit timer/counters and one 8 -bit timer/counter with selectable operating modes
— Watch timer for real time
— 16 channel A/D converter
— 8-bit serial I/O interface
