TABLE 1-2:

BUFFER TYPES

Buffer Type

Description

Input.

Input with Schmitt trigger.

O12

Output buffer with 12 mA sink and 12 mA source.

OD12

Open-drain output with 12 mA sink

50 μA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-

ups are always enabled.

Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on internal

resistors to drive signals external to the device. When connected to a load that must be

pulled high, an external resistor must be added.

50 μA (typical) internal pull-down. Unless otherwise noted in the pin description, internal

pull-downs are always enabled.

Internal pull-down resistors prevent unconnected inputs from floating. Do not rely on

internal resistors to drive signals external to the device. When connected to a load that

must be pulled low, an external resistor must be added.

ICLK

Crystal oscillator input pin

OCLK

Crystal oscillator output pin

I/O-U

Analog input/output defined in USB specification.

I-R

RBIAS.

Analog.

PPower pin.
