THC20F08AD is an 8-bit CPU contact smart card IC with a total of 224 KB FLASH and hardware DES/TRNG/CRC, suitable for general IC card applications, such as SIM card, banking card, Pay-TV card, campus card, city card, etc.

COS developers can flexibly partition the 224 KB FLASH to store code and data. COS can access the high 56 KB FLASH area (meet the requirement of the 64 KB SIM application) from XDATA. COS can access all FLASH area from CODE, because the 64 KB limit can be surmounted by CODE banking.
