SMBus/I C Interfaced 4-Port, Level-Translating  
GPIOs and LED Drivers  
General Description  
Features  
The MAX7306/MAX7307 I2C-/SMBus™-compatible, seri-  
al-interfaced peripherals feature four level-translating  
I/Os and operate from a 1.62V to 3.6V power supply.  
LA  
♦ 1.4V to 5.5V I/O Level Translation Port Supply (V  
♦ 1.62V to 3.6V Power Supply  
)
♦ Four Individually Configurable GPIO Ports  
P1 = Open-Drain I/O  
The MAX7307 features a port supply (V ) that allows  
LA  
level translation on I/O ports to operate from a separate  
power supply from 1.4V to 5.5V. The MAX7306 features  
an address select input (AD0) to allow up to four unique  
slave addresses.  
P2, P3, P4 = Push-Pull or Open-Drain I/O  
♦ Individual 33-Step PWM Intensity Control  
♦ Blink Controls with 15 Steps on Outputs  
♦ 1kHz PWM Period Provides Flicker-Free LED  
The MAX7306/MAX7307 ports P2, P3, and P4 can be  
configured as inputs, push-pull outputs, and open-drain  
outputs. Port P1 can be configured as a general-pur-  
pose input, open-drain output, or an open-drain INT out-  
put. Ports P2 and P3 can be configured as OSCIN and  
OSCOUT, respectively. The MAX7306/MAX7307 include  
an internal oscillator for PWM, blink, and key debounce,  
or to cascade multiple MAX7306/MAX7307s. The exter-  
nal clock can be used to set a specific PWM and blink  
timing. The RST input asynchronously clears the 2-wire  
interface and terminates a bus lockup involving the  
MAX7306/MAX7307.  
Intensity Control  
♦ 25mA (max) Port Output Sink Current (100mA  
max Ground Current)  
♦ Inputs Overvoltage Protected Up to 5.5V (V  
)
LA  
♦ Transition Detection with Optional Interrupt Output  
♦ Optional Input Debouncing  
♦ RST Input Clears Serial Interface, Can Restore  
Power-Up Default State, and Synchronizes Blink  
Timing  
♦ Oscillator Input and Output Enables Cascading  
Multiple Devices  
All ports configured as output feature 33-step PWM,  
allowing any output to be set from fully off, 1/32 to 31/32  
duty cycle, to fully on. All output ports also feature LED  
blink control, allowing blink periods of 1/8 second, 1/4  
second, 1/2 second, 1, 2, 4, or 8 seconds. Any port can  
blink during this period with a 1/16 to 15/16 duty cycle.  
♦ Low 0.75µA (typ) Standby Current
