PRODUCT BRIEF (S3C89K8)
High Performance and Low Power Consumption contact/contactless Smart Card
Microcontroller
The S3C89K8 single-chip CMOS microcontroller is specially designed and packaged for "contact/contact less
smart card" application. The SAM87RC 8-Bit CPU architecture supports Stop and Idle power-down modes to
reduce power consumption. The S3C89K8 has SAM87RC 8-Bit CPU, 24K bytes of program memory (ROM), 8K
bytes of program/data memory (EEPROM), 272-byte general-purpose register file and 512-byte static RAM.
