SMBus/I C Interfaced 9-Port,

Level-Translating GPIO and LED Driver with CLA

General Description

Features

The MAX7302 I²C-/SMBus™-compatible, serial-interfaced

peripheral features 9 level-translating I/Os, and operates

from a 1.62V to 3.6V power supply. The MAX7302 fea-

♦ 1.62V to 5.5V I/O Level-Translation Port Supply (V

♦ 1.62V to 3.6V Power Supply

)

♦ 9 Individually Configurable GPIO Ports

P1 Open-Drain I/O

tures a port supply V that allows level-translation on I/O

ports to operate from a separate power supply from 1.62V

to 5.5V. An address select input, AD0, allows up to four

unique slave addresses for the device.

P2–P9 Push-Pull or Open-Drain I/Os

♦ Individual 33-Step PWM Intensity Control

♦ Blink Controls with 15 Steps on Outputs

The MAX7302 ports P2–P9 can be configured as inputs,

push-pull outputs, and open-drain outputs. Port P1 can

be configured as a general-purpose input, open-drain

output, or an open-drain INT output. Ports P2–P9 can be

configured as OSCIN and OSCOUT, respectively. Ports

P2–P9 can also be used as configurable logic arrays

(CLAs) to form user-defined logic gates, replacing exter-

nal discrete gates. Outputs are capable of sinking up to

25mA, and sourcing up to 10mA when configured as

push-pull outputs.

♦ 1kHz PWM Period Provides Flicker-Free LED

Intensity Control

♦ 25mA (max) Port Output Sink Current (100mA

max Ground Current)

♦ Inputs Overvoltage Protected Up to 5.5V (V

)

♦ Transition Detection with Optional Interrupt Output

♦ Optional Input Debouncing

♦ I/O Ports Configurable as Logic Gates (CLA)

♦ External RST Input

The MAX7302 includes an internal oscillator for PWM,

blink, and key debounce, or to cascade multiple

MAX7302s. The external clock can be used to set a spe-

cific PWM and blink timing. The RST input asynchronous-

ly clears the 2-wire interface and terminates a bus lockup

involving the MAX7302.

♦ Oscillator Input and Output Enable Cascading

Multiple Devices

♦ Low 0.75µA (typ) Standby Current

PACKAGE

PKG

CODE

All ports configured as an output feature a 33-step PWM,

allowing any output to be set from fully off, 1/32 to 31/32

duty cycle, to fully on. All output ports also feature LED

blink control, allowing blink periods of 1/8s, 1/4s, 1/2s, 1s,

2s, 4s, or 8s. Any port can blink during this period with a

1/16 to 15/16 duty cycle.
