8 / 61 page  Description SMSxxxAF, SMSxxxFF, SMSxxxBF 8/61 1 Description The Secure Digital Memory Card (SD Memory Card) is a Flash-Based Memory Card. It is specifically designed to meet the security, capacity, performance and environmental requirements of the latest-generation audio and video consumer electronic devices, that is mobile phones, digital cameras, digital recorders, PDAs, organizers, electronic toys, etc. The Secure Digital Memory Card is a high-mobility, high-performance, low-cost and low- power consumption device that features high data throughput at the memory card interface. It includes a copyright protection mechanism that complies with the security of the SDMI (Secure Digital Music Initiative) standard. The Secure Digital Memory Card security system uses mutual authentication and a “cipher algorithm” that protects the card from illegal use. Unsecured access to the user's personal content is also available. The Secure Digital Memory Cards have an advanced communication interface designed to operate in a low voltage range. The full-size Secure Digital Memory Card has a 9-pin interface whereas the Mini Secure Digital Memory Card has a 11-pin interface but can be fitted with a 9-pin adapter. Only the 9-pin interface is described in this document. The MicroSD Memory Card has an 8-pin interface, and can also be fitted with a 9-pin adapter. Table 2, Table 3, Table 4, Table 5, and Table 6 give an overview of the Secure Digital Memory Card features. In order to meet environmental requirements, the devices are offered in ECOPACK® packages. ECOPACK packages are Lead-free. The category of second Level Interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. The SD, MiniSD and MicroSD packages are also Halogen free and Antimony free.
