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.
