Test System Configuration 4 Test Head Filling and DUT Board Considerations

System Reference, January 2001

Utility, EEPROM and HPMU

According to drawings

D-E6980-96540-1S24D

(512 pins) and

D-E6980-96550-1S24D

(1024 pins)

For utility pads on the probe

card see Table 23 and Table 24

on page 112.

The Read/Write utility lines allow you to control external

devices such as relays, solenoids or indicators, depending

on the application. The utility lines are implemented as

open collector output with a maximum current of 75 mA

and a maximum voltage of 50 V.

NOTE Utility lines are not affected by standard connect/discon-

nect sequences but only controlled by dedicated test func-

tion/firmware commands. This allows the utility line to

assume a steady state setup before the actual testflow

takes control, and to remain in this state even after test

execution has been completed.

The functions of the utility pads of the 512 pin and the

1024 pin SOC series DUT boards are illustrated in

Table 17 and Table 19. For the position and numbering of

the utility blocks see Figure 42 on page 86.

NOTE The numbering of the utility blocks differs from the

numbering of the DPS blocks which is the same as for the

groups.

In Table 17 and Table 19, a and b refers to the two

columns of 17 pads each of a utility block (see also the

drawing of a utility block on the left of Table 17).

The utility pads have got the following functions:

• URW# are the Utility Read-Write lines.

• UW# are the Utility Write-Only lines.

• UGND is the Utility Ground which is isolated from the

system GND to avoid noise.

• UP5V is the 5 V power supply.
