4-Wire-Interfaced, 2.5V to 5.5V, 20-Port and

28-Port I/O Expander

General Description

Features

The MAX7301 compact, serial-interfaced I/O expander

(or general-purpose I/O (GPIO) peripheral) provides

microprocessors with up to 28 ports. Each port is indi-

vidually user configurable to either a logic input or logic

output.

♦ High-Speed 26MHz SPI-/QSPI-™/MICROWIRE™-

Compatible Serial Interface

♦ 2.5V to 5.5V Operation

♦ -40°C to +125°C Temperature Range

Each port can be configured either as a push-pull logic

output capable of sinking 10mA and sourcing 4.5mA,

or a Schmitt logic input with optional internal pullup.

Seven ports feature configurable transition detection

logic, which generates an interrupt upon change of port

logic level. The MAX7301 is controlled through an

SPI™-compatible 4-wire serial interface.

♦ 20 or 28 I/O Ports, Each Configurable as

Push-Pull Logic Output

Schmitt Logic Input

Schmitt Logic Input with Internal Pullup

♦ 11µA (max) Shutdown Current

♦ Logic Transition Detection for Seven I/O Ports

The MAX7301AAX and MAX7301ATL have 28 ports and

are available in 36-pin SSOP and 40-pin TQFN packages,

respectively. The MAX7301AAI has 20 ports and is avail-

able in a 28-pin SSOP package.
