Notes
1. Each SPD defines the physical attributes of each bank or group of banks. If both banks of a
SODIMM are populated, they are the same speed and memory size.
2. This is a dual address serial EEPROM.
3. The device address is user selectable using switches on the RTM. The recommended address
setting for the MVME3100 is $AA.
User Configuration EEPROM
The MVME3100 board provides two 64KB dual address serial EEPROMs for a total of 128KB user
configuration storage. These EEPROMs are hardwired to have device IDs as shown in
page
29, and each device ID will not be used for any other function. Refer to the 2-Wire Serial EEPROM
Datasheet listed in
VPD EEPROM
The MVME3100 board provides an 8KB dual address serial EEPROM containing vital product data
(VPD) configuration information specific to the MVME3100. Typical information that may be present in
the EEPROM may include: manufacturer, board revision, build version, date of assembly, memory
present, options present, L2 cache information, etc. The VPD EEPROM is hardwired to have a device
ID as shown in
A, Related
Documentation, for additional details.
