2 Pin Description
2.2 T8110L Pinout Information
The T8110L package is a 272-pin PBGA ball grid array. Refer to the table below for ball assignment, buffer type,
and pull-up/pull-down information.
Note: The pull-up/down column in the following table is defined as follows:

20 k
50 k
LPUE: 50 k
Enabled: 50 k up/20 k Vpre—when H100_ENABLE = 1, a 50 k pull-up resistor is in-circuit (see Figure 1 on
page 20). When H110_ENABLE = 1, a 20 k pull-down resistor from the VPRECHARGE input to this signal is in-
circuit.
down—20 k
up—50 k
up—when LPUE = 1, a 50 k pull-up resistor is in-circuit.
pull-up resistor is always in-circuit.
pull-down resistor is always in-circuit.
