4 1. Overview The (ISD) of the SQFlash is fully compliant to the specification released by SD Card Association. The Command List supports [Part 1 Physical Layer Specification Ver2.0 Final] definitions. Card Capacity of Non-secure Area, Secure Area Supports [Part 3 Security Specification Ver2.0 Final] Specifications. The SQF-ISD is based on 9-pin interface, designed to operate at a maximum operating frequency of 50MHz. It can alternate communication protocol between the SD mode and SPI mode. It performs data error detection and correction with very low power consumption. More importantly, the ISD of the SQFlash offers a wide range of storage capacities. The SQF-ISD is specifically made for any rigorous environments where devices need to be operated at extended temperature, and strong data integrity and reliability are demanded. Such environments include both industrial and automotive applications. The SQF-ISD is the best choice for exceptional reliability, excellent performance and wide compatibility.

They start to operate as DAT lines after SET_BUS_WIDTH command. The Host shall keep its own DAT1-DAT3 lines in input mode, as well, while they are not used. It is defined so, in order to keep compatibility to MultiMedia Cards. (3) At power up this line has a 50KOhm pull up enabled in the card. This resistor serves two functions Card detection and Mode Selection. For Mode Selection, the host can drive the line high or let it be pulled high to select SD mode. If the host wants to select SPI mode it should drive the line low. For Card detection, the host detects that the line is pulled high. This pull-up should be disconnected by the user, during regular data transfer, with SET_CLR_CARD_DETECT (ACMD42) command.
