IS23SC4456,IS23SC4456 Card

IS23SC4456,  Contactless CPU Card IC

IS23SC4456 is targeting at contactless smart card applications such as e-transfer, e-ticket, electronic purse, security access and multi-applications in one-card purposes.

IS23SC4456 offers 8K bytes of STS-ROM, 24K bytes of User-ROM (for user COS debugging purpose, an emulation IC whose user-ROM is replaced with EEPROM can be provided), 256 bytes internal RAM, 768 bytes XRAM, 256 bytes RF-buffer and 8 Kbytes EEPROM, which can be used as both data and program memory. The non-volatile memory consists of high reliability cells to guarantee data integrity. This is especially important when the EEPROM is used as program memory.

IS23SC4456 RF interface conform to ISO/IEC 14443 type A.
