8-Port I/O Expander with LED Intensity  
Control, Interrupt, and Hot-Insertion Protection  
General Description  
Features  
2
The MAX7315 I C-/SMBus-compatible serial interfaced  
peripheral provides microprocessors with 8 I/O ports.  
Each I/O port can be individually configured as either an  
open-drain current-sinking output rated at 50mA at 5.5V,  
or a logic input with transition detection. A ninth port can  
be used for transition detection interrupt or as a general-  
purpose output. The outputs are capable of directly dri-  
ving LEDs, or providing logic outputs with external  
resistive pullup up to 5.5V.  
o 400kbps, 2-Wire Serial Interface, 5.5V Tolerant  
o 2V to 3.6V Operation  
o Overall 8-Bit PWM LED Intensity Control  
Global 16-Step Intensity Control  
Plus Individual 16-Step Intensity Control  
o Automatic Two-Phase LED Blinking  
o 50mA Maximum Port Output Current  
o Supports Hot Insertion  
PWM current drive is integrated with 8 bits of control.  
Four bits are global control and apply to all LED outputs  
to provide coarse adjustment of current from fully off to  
fully on in 14 intensity steps. Each output then has indi-  
vidual 4-bit control, which further divides the globally  
set current into 16 more steps. Alternatively, the current  
control can be configured as a single 8-bit control that  
sets all outputs at once.  
o Outputs Are 5.5V-Rated Open Drain  
o Inputs Are Overvoltage Protected to 5.5V  
o Transition Detection with Interrupt Output  
o Low Standby Current (1.2µA typ; 3.3µA max)  
o Tiny 3mm x 3mm, Thin QFN Package  
o -40°C to +125°C Temperature Range  
o All Ports Can Be Configured as Inputs or Outputs  
The MAX7315 is pin and software compatible with the  
PCA9534 and PCA9554(A).  
Each output has independent blink timing with two blink  
phases. All LEDs can be individually set to be on or off  
during either blink phase, or to ignore the blink control.  
The blink period is controlled by a register.

The MAX7315 supports hot insertion. All port pins, the INT  
output, SDA, SCL, and the slave address inputs ADO-2  
remain high impedance in power-down (V+ = 0V) with up  
to 6V asserted upon them.  
The MAX7315 is controlled through the 2-wire I2C/SMBus  
serial interface, and can be configured to one of 64 I2C  
addresses.
