I C-Interfaced Key-Switch Controller and LED  
Driver/GPIOs with Integrated ESD Protection  
General Description  
Features  
The MAX7360 I2C-interfaced peripheral provides micro-  
processors with management of up to 64 key switches,  
with an additional eight LED drivers/GPIOs that feature  
constant-current, PWM intensity control, and rotary  
switch control options.

ꢀonꢃtant0ꢀurrent LED Drive  
The key-switch drivers interface with metallic or resis-  
tive switches with on-resistances up to 5kI. Key inputs  
are monitored statically, not dynamically, to ensure  
low-EMI operation. The MAX7360 features autosleep  
and autowake modes to further minimize the power  
consumption of the device. The autosleep feature puts  
the device in a low-power state (1FA typ) after a sleep  
timeout period. The autowake feature configures the  
MAX7360 to return to normal operating mode from sleep  
upon a keypress.

S Monitorꢃ Up to ꢁ- Keyꢃ  
The key controller debounces and maintains a FIFO of  
keypress and release events (including autorepeat, if  
enabled). An interrupt (INTK) output can be configured  
to alert keypresses, as they occur, or at maximum rate.  
S Key0Switcꢄ Interrupt (INTK) on Eacꢄ Debounced  
Event/FIFO Level, or End of Definable Time Period  
S Port Interrupt (INTI) for Input Portꢃ for Special0Key  
There are eight open-drain I/O ports, which can be used  
to drive LEDs. The maximum constant-current level for  
each open-drain port is 20mA. The intensity of the LED  
on each open-drain port can be individually adjusted  
through a 256-step PWM control. An input port pair  
(PORT6, PORT7) can be configured to accept 2-bit gray  
code inputs from a rotary switch. In addition, if not used  
for key-switch control, up to six column pins can be used  
as general-purpose open-drain outputs (GPOs) for LED  
drive or logic control.
