THC80F09AD-B is a 32-bit CPU contact smart card IC with a total of 280 KB FLASH and hardware DES/TRNG/CRC, suitable for general IC card applications, such as SIM, Banking Card, Pay-TV Card, Campus Card, City Card, etc. The developers can divide the memory into different parts and size for different priority.To facilitate software development, the IC embeds hardware DES/ TRNG/ CRC. COS developers can enjoy smaller code size and less execution time. For better security and reliability, the IC offers many hardware security features, e.g., Write-protection for a configurable FLASH area, High/low voltage and high/low clock frequency detection, etc.
