NOTES:
1. Each SPD defines the physical attributes of each bank or group of banks.
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 ADT7461 is $AA.

User Configuration EEPROM

The 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
Table 4-4 on page
the EEPROM Datasheet listed in
details.
4.7

VPD EEPRO

The MVME7100ET board provides an 8KB dual address serial EEPROM containing Vital
Product Data (VPD) configuration information specific to the MVME7100ET. 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, and so on. The VPD EEPROM is hardwired to have a device ID as shown in
Table 4-4 on page
Documentation, for additional details.
