18-Port GPIO with LED Intensity Control,

Interrupt, and Hot-Insertion Protection

General Description

Features

The MAX7314 I²C™-compatible serial interfaced periph-

eral provides microprocessors with 16 I/O ports plus one

output-only port and one input-only port. Each I/O port

can be individually configured as either an open-drain

current-sinking output rated at 50mA and 5.5V, or a logic

input with transition detection. The output-only port can

be assigned as an interrupt output for transition detec-

tion. The outputs are capable of driving LEDs, or provid-

ing logic outputs with external resistive pullup up to 5.5V.

♦ 400kbps, 2-Wire Serial Interface, 5.5V Tolerant

♦ 2V to 3.6V Operation

♦ Overall 8-Bit PWM LED Intensity Control

Global 16-Step Intensity Control

Individual 16-Step Intensity Controls

♦ 2-Phase LED Blinking

♦ 50mA Maximum Port Output Current

♦ Supports Hot Insertion

Eight-bit PWM current control is built in for all 17 output

ports. A 4-bit global control applies to all LED outputs

and provides coarse adjustment of current from fully off

to fully on with 14 intensity steps in between. Each out-

put has an individual 4-bit control, which further divides

the globally set current into 16 more steps.

Alternatively, the current control can be configured as a

single 8-bit control that sets all outputs at once.

♦ Outputs are 5.5V-Rated Open Drain

♦ Inputs are Overvoltage Protected to 5.5V

♦ Transition Detection with Interrupt Output

♦ 1.2µA (typ), 3.6µA (max) Operating Current

♦ Small 4mm x 4mm, Thin QFN Package

♦ -40°C to +125°C Temperature Range

Each output has independent blink timing with two blink

phases. All LEDs can be individually set to be on or off

during either blink phase, or to ignore the blink control.

The blink period is controlled by a clock input (up to 1kHz)

on BLINK or by a register. The BLINK input can also be

used as a logic control to turn the LEDs on and off, or as a

general-purpose input.

The MAX7314 supports hot insertion. All port pins, the

INT output, SDA, SCL, RST, BLINK, and the slave

address input ADO remain high impedance in power-

down (V+ = 0V) with up to 6V asserted upon them.

Typical Application Circuit

The MAX7314 is controlled through a 2-wire serial inter-

face, and uses four-level logic to allow four I²C

addresses from only one select pin.
