1 Page 1 of 24 microSDHC memory card Flash Storage Media 1. Introduction Industrial-temperature microSD cards are designed, manufactured and tested to withstand extreme environmental conditions. They are suited to outdoor applications such as kiosks, fuel pumps, ATMs, media gateways and automotive/marine. They are also ideal for Internet of Things (IoT) applications for use in the latest industrial applications. The High Capacity microSD memory card is functionally compatible with the SD memory specification but is smaller in dimension. This microSDHC memory card can also be inserted into a microSDHC memory card adapter and used as a standard Secure Digital memory card. 2.

Do not use NC pins. Page 4 of 24 microSD Card Bus Topology The microSD Memory Card supports two alternative communication protocols: SD and SPI Bus mode. The host system can choose either one of the modes.

5 The same data on the microSD Card can be read and written by both modes. SD mode allows 4-bit high-performance data transfer. SPI mode supports the easy and common interface for SPI channel. The disadvantage of this mode is the loss of performance relative to the SD mode. SD Bus Mode Protocol The SD bus allows the dynamic configuration of the number of data lines from 1 to 4 bi- directional data signals. After power up, the microSD card will use only DAT0 by default. After initialisation, the host can change the bus width. Multiplied microSD card connections are available to the host. Common Vdd, Vss and CLK signal connections are available in the multiple connection. However, Command, Response and Data lines (DAT0-DAT3) are divided for each card from the host. This feature allows an easy trade-off between hardware cost and system performance.

6 Communication over the microSD bus is based on a command and data bit stream initiated by a start bit and terminated by stop bit. Command: Commands are transferred serially on the CMD line. A command is a token to start an operation from the host to the card. Commands are sent to a addressed single card (addressed command) or to all connected cards (broadcast command). Response: Responses are transferred serially on the CMD line. A response is a token to answer a previously received command. Responses are sent from an addressed single card or from all connected cards. Data: Data can be transferred from the card to the host or vice versa. Data is transferred via the data lines.

8 CMD4 is not implemented because of DSR register (optional register) CMD56 is for vendor-specific commands which are not defined in the standard card. Page 7 of 24 SPI Bus Mode Protocol The SPI bus allows 1 bit data line by 2-channel (Data In and Out). SPI compatible mode allows the MMC host systems to use the SD card with little change. The SPI bus mode protocol is byte transfer. All the data tokens are multiples of bytes (8-bit) and are always byte-aligned to the CS signal. The advantage of SPI mode is the reduction in host design effort. Specifically, the MMC host can be modified with little change. The disadvantage of SPI mode is the loss of performance versus SD mode. Caution: Please use SD Card specification. DO NOT use MMC specification. For example, initialisation is achieved by ACMD41, and be careful with registers.
