2 Product Specification
The SD Memory Card is a small form factor non-volatile memory card which provides high capacity data
storage. Its aim is to capture, retain and transport data, audio and images, facilitating the transfer of all
types of digital information between a large variety of digital systems.
The card operates in two basic modes:
SDHC/SDXC and UHS-I card modes
SPI mode
The SD Memory Card also supports SD Default and High Speed mode with up to 50MHz clock frequency
as well as UHS-I modes DDR50, SDR12/25/50/104 with up to 208MHz clock frequency.
SD Memory card Specification Part 1, Physical layer Specification V3.01
SD Memory card Specification Part 2, File System Specification V3.00
SD Memory card Specification Part 3, Security Specification V3.00
SD Memory Card Addendum V4.00
Simplified specifications are available at https://www.sdcard.org/downloads/pls/simplified_specs/
The Card has an internal intelligent controller which manages interface protocols, data storage and retrieval
as well as hardware BCH Error Correction Code (ECC), defect handling, diagnostics and clock control.
The advanced wear leveling mechanism assures an equal usage of the Flash memory cells to extend the life
time.
The hardware BCH-code ECC allows to detect and correct up to 40 defect bits per 1kByte.
The controller performs control read operations and checks the consistence of the data. If an error of some
bits is detected, the card refreshes all data in the flash cells to prevent data retention problems.
The card has a power-loss management feature to prevent data corruption after power-down.
The cards are RoHS compliant and lead-free.

Notes:

2) The extended DAT lines (DAT1-DAT3) are input on power up. 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.
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
4) DAT1 line may be used as Interrupt Output (from the Card) in SDIO mode during all the times that it
is not in use for data transfer operations (refer to "SDIO Card Specification" for further details).
5) DAT2 line may be used as Read Wait signal in SDIO mode (refer to "SDIO Card Specification" for
further details).

5.2 Power up / Power down beaviour and reset
5.2.1 Power up
When the voltage is ramped up the controller is ready (internal reset pin released) if the voltage reaches
1.65V. The host can start with communication 1ms after 2.7V is reached according the SDA soecification. That
should perform 74 clock cycles and start with the sequence CMD0, CMD8, ACMD41 until card is ready as
described in the SD specification 3.01.
5.2.2 Power down
When the power falls below 2.6V the controller stopps the communication to the flash, but enables the
flash to finish a started flash program operation (if voltage drop is not fast).
After next initialization the controller checks the last written data for consistency and refreshs the data.
Either the new or the old data (if the write operation could not be finished) are available.
5.2.3 Power drop
If the voltage drops below 2.6V and rises again, the card performes a reset. The card must be initialized like
after a power on.
5.2.4 Operation below minimum voltage
If the card initialization is perfomed below the specified voltage of 2.7V, the card may be detected as 1MB
card with no usefull data. In this case the host should power off and on the card and start initialization
above 2.7V.

6 Host access Specification
The following chapters summarize how the host accesses the card:
Chapter 6.1 summarizes the SD and SPI buses.
Chapter 4summarizes the registers.
6.1 SD and SPI Bus Modes
The card supports SD and the SPI Bus modes. Application can chose either one of the modes. Mode selection
is transparent to the host. The card automatically detects the mode of the reset command and will expect
all further communication to be in the same communication mode. The SD mode uses a 4-bit high
performance data transfer, and the SPI mode provides compatible interface to MMC host systems with little
redesign, but with a lower performance.
6.1.1 SD Bus Mode Protocol
The SD Bus mode has a single master (host) and multiple slaves (cards) synchronous topology. Clock, power,
and ground signals are common to all cards. After power up, the SD Bus mode uses DAT0 only; after
initialization, the host can change the cards’ bus width from 1 bit (DAT0) to 4 bits (DAT0-DAT3). In high
speed mode, only one card can be connected to the bus.
Communication over the SD bus is based on command and data bit streams which are initiated by a start
bit and terminated by a stop bit.
Command: a command is a token which starts an operation. A command is sent from the host
either to a single card (addressed command) or to all connected cards (broadcast command). A
command is transferred serially on the CMD line.
Response: a response is a token which is sent from an addressed card, or (synchronously) from all
connected cards, to the host as an answer to a previously received command. A response is
transferred serially on the CMD line.
Data: data can be transferred from the card to the host or vice versa. Data is transferred via the
data lines.
6.1.2 SPI Bus Mode Protocol
The Serial Parallel Interface (SPI) Bus is a general purpose synchronous serial interface. The SPI mode
consists of a secondary communication protocol. The interface is selected during the first reset command
after power up (CMD0) and it cannot be changed once the card is powered on.
While the SD channel is based on command and data bit streams which are initiated by a start bit and
terminated by a stop bit, the SPI channel is byte oriented. Every command or data block is built of 8-bit
bytes and is byte aligned to the CS signal.
The card identification and addressing methods are replaced by a hardware Chip Select (CS) signal. There
are no broadcast commands. For every command, a card (slave) is selected by asserting (active low) the CS
signal.
The CS signal must be continuously active for the duration of the SPI transaction (command, response and
data). The only exception occurs during card programming, when the host can de-assert the CS signal
without affecting the programming process.
The bidirectional CMD and DAT lines are replaced by unidirectional
dataIn
and
dataOut
signals.

Data Out

Power and ground
6.1.3 Mode Selection
The SD Memory Card wakes up in the SD mode. It will enter SPI mode if the CS signal is asserted (negative)
during the reception of the reset command (CMD0) and the card is in
idle_state
. If the card recognizes that
the SD mode is required it will not respond to the command and remain in the SD mode.
If SPI mode is required the card will switch to SPI and respond with the SPI mode R1 response.

CH-9552 Bronschhofen www.swissbit.com S-46_data_sheet_SD-LxBM_Rev091.docx
Switzerland industrial@swissbit.com Page 12 of 19
The only way to return to the SD mode is by entering the power cycle. In SPI mode the SD Memory Card
protocol state machine is not observed. All the SD Memory Card commands supported in SPI mode are
always available.
During the initialization sequence, if the host gets Illegal Command indication for ACMD41 sent to the card,
it may assume that the card is Multimedia Card. In that case it should re-start the card as Multimedia Card
using CMD0 and CMD1.
6.2 Card Registers
