MAX6957  
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.  
● High-Speed 26MHz SPI-/QSPI™-/MICROWIRE®-  
Compatible Serial Interface  
● 2.5V to 5.5V Operation  
● -40°C to +125°C Temperature Range  
● 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  
● 11µA (max) Shutdown Current  
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.  
● 16-Step Individually Programmable Current Control  
for Each LED  
● Logic Transition Detection for Seven I/O Ports  
Ordering Information  
PIN-  
The MAX6957AAX and MAX6957ATL have 28 ports and  
are available in 36-pin SSOP and 40-pin TQFN (6mm x  
6mm) packages, respectively. The MAX6957AAI and  
MAX6957ANI have 20 ports and are available in 28-pin  
SSOP and 28-pin DIP packages, respectively.
