EMBEDDED EPCDFBA # 219 B2 Industrial Control Card Module
Technical data of product parameters
The serial EEPROM can be viewed as two separate and distinct 256 byte
SROMs. The first 256 byte portion of such a device contains the product’s EMBEDDED EPCDFBA # 219 B2
vital product data (VPD). The second 256 byte portion contains the local
memory configuration serial presence detect (SPD) data. The MVME2400 EMBEDDED EPCDFBA # 219 B2
VPD SROM is located at I2C address 0xA0 and the MVME2400 SPD
SROM is located at I2C address 0xA8.
Vital product data contains static board build information that is typcially
used for board initialization, configuration, and verification. Each board
has its own unique VPD SROM containing local hardware configuration
information.
The VPD consists of a header section, followed by contiguous formatted
data packets. The header section consists of eye-catcher and size fields, EMBEDDED EPCDFBA # 219 B2
and the data packets consist of identifier, data length, and data content
fields.
The header section begins with an eye-catcher field that can be used to
verify the existence of an initialized VPD SROM (an optional EEPROM
CRC packet may also be used to verify the integrity of the VPD content).
The “size” field contains the total number of bytes assigned to the VPD
portion of the SROM.
Each packet begins with a unique identifier field that defines the content EMBEDDED EPCDFBA # 219 B2
and data structure of the packet’s data section. The data length field
contains the size of the data section in bytes. This is also added to the data
section base address to locate the starting address of the following VPD
packet. Different data section lengths are sometimes used to denote
different revision levels or array sizes for packets of a particular identifier.
Packets must be contiguous but may be placed in any order.
