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

28-Port LED Display Driver and I/O Expander

General Description

Features

The MAX6957 compact, serial-interfaced LED display

driver 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, logic

output, or common-anode (CA) LED constant-current

segment driver. Each port configured as an LED seg-

ment driver behaves as a digitally controlled constant-

current sink, with 16 equal current steps from 1.5mA to

24mA. The LED drivers are suitable for both discrete

LEDs and CA numeric and alphanumeric LED digits.

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

Compatible Serial Interface

o 2.5V to 5.5V Operation

o -40°C to +125°C Temperature Range

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

Constant-Current LED Driver

Push-Pull Logic Output

Schmitt Logic Input

Schmitt Logic Input with Internal Pullup

Each port configured as a GPIO can be either 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 MAX6957 is controlled

through an SPI™-compatible 4-wire serial interface.

o 11µA (max) Shutdown Current

o 16-Step Individually Programmable Current

Control for Each LED

o Logic Transition Detection for Seven I/O Ports

The MAX6957AAX and MAX6957ATL have 28 ports and

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

respectively. The MAX6957AAI and MAX6957ANI have

20 ports and are available in 28-pin SSOP and 28-pin DIP

packages, respectively.
