7. SD Card Interface
7-1 SD-IP
¢ Overview
The SD Memory Card, which is being jointly developed by Panasonic Corporation, Toshiba Corporation and SanDisk
Corporation, is a memory card with a copyright protection function. Matsushita was the first company to develop an SD
host I/F controller embedded with an authentication and cryptographic calculation module. We ensured the quality of the
controller dy dctailed verification with the RTL and an evaluation board. Finally, we designated the controller as IP (Intellectual
Property) by means of careful documentation and have maintained the design data which is easily reusable.

Note 1) For using this IP, it is necessary to enter into the SD HALA (Host/Ancillary Product License Agreement) in advance with SD-3C-LLC which is a limited liability company in
Delaware in the USA, and with the SD Card Association which is a nonprofit company in California, USA. This function is not available if you have not entered into the SD HALA.
Note 2) For using the CPRM technology of this IP, it is necessary to enter into the 4C CPPM/CPRM License Agreement or CPRM For SD-binding License Agreement in advance with
4C Entity in Delaware, USA, and Founders (International Business Machines Corporation, Intel Corporation, Panasonic Corporation, and Toshiba Corporation). This function is
not available if you have not entered into the 4C CPPM/CPRM License Agreement or CPRM For SD-binding License Agreement.
Note: Detailed information regarding this product will be disclosed upon conclusion of an NDA (Non-Disclosure Agreement).
