CMOS Microcontroller for

Smart Card Applications

Advanced Information

Publication Number 31-S3-CC91A

March 2006 (Rev.0)

OVERVIEW

The S3CC91A single-chip CMOS micro-controller is designed for smart card applications and is fabricated using

an advanced 0.13-micron CMOS process. Its fast and reliable 16-bit CPU is bad on the CalmRISC16 CPU

architecture and follows Harvard style.

The S3CC91A has 36K bytes EEPROM, 6K bytes RAM, 192K bytes ROM, a 16-bit random number generator, a

16-bit timer, a power-on ret, asynchronous rial I/O interface and numerous curity circuits.
