MultiMediaCard

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:
