I²C-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.

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.

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.

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.
