7.4I2C Bus Device Addressing

The following table contains the I2C devices used for the MVME2500 and its assigned device address.

Table 7-3 I2C Bus Device Addressing

I2C Bus Address	Device Function	Size	Notes

0x50	SPD	256 x 8

0x4C	ADT 7461 Temperature Sensor	N/A

0x68	DS 1375 real-time clock	N/A

0x54	VPD	8192 x 8	1

0x52	User configuration	65536 x 8	1

0x53	User configuration	65536 x 8	1

0x55	RTM EEPROM	8192 X 8	1, 2

0x56	XMC EEPROM	N/A	3

1.This is a dual address serial EEPROM.

2.The RTM Bus address can be manually changed through the S1 Switch on RTM. The default switch configuration will set the address to 0x55. Make sure that the address is unique to the RTM Bus address when setting the switch.

3.The address of the XMC EEPROM is configured through Geographic Address resistor on board.

7.5Ethernet PHY Address

The assigned Ethernet PHY on the MII management bus is shown in the following table.

Table 7-4 PHY Types and MII Management Bus Address

			PHY MIIM
Ethernet Port	Function / Location	PHY Types	Address

TSEC1	Gigabit Ethernet port routed to front panel	BCM54616	1
