CMOS Microcontroller for
Smart Card Applications
OVERVIEW
The S3CC9ED single-chip CMOS micro-controller is designed for low voltage smart card applications and is
fabricated using an advanced 0.18-micron CMOS process. Its fast and reliable 16-bit CPU is based on the smart
card-purpose CalmRISC16 processor.
