Buffer Types

Note: The digital signals are not 5V tolerant. Refer to Section 5.1, "Absolute Maximum Ratings*," on

page 66 for additional buffer information.

Note 2.3

Sink and source capabilities are dependant on the VDDIO voltage. Refer to Section 5.1,

"Absolute Maximum Ratings*," on page 66 for additional information.

BUFFER TYPE

DESCRIPTION

Schmitt-triggered input

O12

Output with 12mA sink and 12mA source

VIS

Variable voltage Schmitt-triggered input

VO8

Variable voltage output with 8mA sink and 8mA source

VOD8

Variable voltage open-drain output with 8mA sink

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

ups are always enabled.

Note:

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.

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

pull-downs are always enabled.

Note:

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.

Analog input

AIO

Analog bi-directional

ICLK

Crystal oscillator input pin

OCLK

Crystal oscillator output pin

Power pin
