MultiMediaCard
TM

Sep.22.2005
Revision 0.3
MID
An 8 bit binary number that identifies the card manufacturer. The MID number is controlled, defined and allocated to a Mul-
tiMediaCard manufacturer by the MMCA. This procedure is established to ensure uniqueness of the CID register.
OID
A 16 bit binary number that identifies the card OEM and/or the card contents (when used as a distribution media either on
ROM or FLASH cards). The OID number is controlled, defined and allocated to a MultiMediaCard manufacturer by the
MMCA. This procedure is established to ensure uniqueness of the CID register.
PNM
The product name is a string, 6 ASCII characters long.
PRV
The product revision is composed of two Binary Coded Decimal (BCD) digits, four bits each, representing an “n.m” revi-
sion number. The “n” is the most significant nibble and “m” is the least significant nibble.
As an example, the PRV binary value field for product revision “6.2” will be: 0110 0010
PSN
A 32 bits unsigned binary integer.
MDT
The manufacturing date is composed of two hexadecimal digits, four bits each, representing a two digits date code m/y;
The “m” field, most significant nibble, is the month code. 1 = January.
The “y” field, least significant nibble, is the year code. 0 = 1997.
As an example, the binary value of the MDT field for production date “April 2000” will be: 0100 0011
CRC
CRC7 checksum (7 bits). This is the checksum of the CID contents computed according to Chapter 6.4.
5.5.3 CSD Register
The Card-Specific Data register provides information on how to access the card contents. The CSD defines the data for-
mat, error correction type, maximum data access time, data transfer speed, whether the DSR register can be used etc.
The programmable part of the register (entries marked by W or E, see below) can be changed by CMD27. The type of the
entries in the table below is coded as follows:
