PIN DESCRIPTIONS

Descriptions of the pins are listed in Table 3-1. The pin types are described in Table 3-2.

The pin types are described in detail in Table 3-2.

3.1

Pin Configurations

The EMC2301/2/3/5 family has four (4) variants that

include features unique to each device. Refer to

Table 3-1 to determine applicability of the pin

descriptions.

3.1.1

SMDATA - SMBUS DATA

This is the open drain, bidirectional data pin for SMBus

communication. Requires external pull-up resistor.

3.1.2

SMCLK - SMBUS CLOCK

This is the input clock pin for SMBus communication.

Requires external pull-up resistor.

3.1.3

VDD - POWER SUPPLY

This pin is the input power supply for the device.

3.1.4

ADDR_SEL - ADDRESS SELECT

Available only on the EMC2303 and EMC2305, this pin

allows user programmability of the SMBus address.

Requires external pull-up resistor.

PIN TYPES

Type

Description

Power This pin is used to supply power or ground

to the device.

Digital Input: this pin is used as a digital

input. This pin is 5V tolerant.

Push/Pull Digital Output: this pin is used as

a digital output. It can both source and sink

current.

DIOD Digital Input/Open Drain Output: this pin is

used as a digital I/O. When it is used as an

output, it is open drain and requires a

pull-up resistor. This pin is 5V tolerant.

Open Drain Digital Output - this pin is used

as a digital output. It is open drain and

requires a pull-up resistor. This pin is 5V

tolerant.

AIO

Analog input/output. This pin is used for

analog signals.
