Description
TS2GSD150 is a 2GB Secure Digital Card of 150X
ultra-high performance. It is specifically designed to
meet the security, capacity, performance and small
form factor requirements in newly emerging audio
and video consumer electronic devices. Based on
dual channel technology and high quality SLC (Single
Level Cell) NAND flash chip, TS2GSD150 is the ideal
companion to bring out the most from your
high-performance electronic devices.

  • Page 3: Bus Protocol

    Note that the Multiple Block operation mode is better for faster write operation. A multiple block transmission is terminated when a stop command follows on the CMD line. Data transfer can be configured by the host to use single or multiple data lines. Transcend Information Inc.
  • Page 4 Each token is protected by CRC bits so that transmission errors can be detected and the operation may be repeated. Response tokens have four coding schemes depending on their content. The token length is either 48 or 136 bits. Transcend Information Inc.
  • Page 5 CRC bits, are transmitted for every one of the DAT lines. CRC bits are calculated and checked for every DAT line individually. The CRC status response and Busy indica-tion will be sent by the card to the host on DAT0 only (DAT1-DAT3 during that period are don’t care). Transcend Information Inc.
  • Page 6 In case of a data retrieval error, the card will not transmit any data. Instead, a special data error token will be sent to the host Figure 12 shows a data read operation which terminated with an error token rather than a data block. Transcend Information Inc.
  • Page 7 After a data block has been received, the card will respond with a data-response token. If the data block has been received without errors, it will be programmed. As long as the card is busy programming, a continuous stream of busy tokens will be sent to the host (effectively holding the DataOut line low). Transcend Information Inc.
