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.

S Integrated ESD Protection

Q8kV IEC 61000-4-2 Contact Discharge

Q15kV IEC 61000-4-2 Air-Gap Discharge

S +14V Tolerant, Open-Drain I/O Ports Capable of

Constant-Current LED Drive

The key-switch drivers interface with metallic or resistive

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 Rotary Switch-Capable Input Pair (PORT6, PORT7)

S 256-Step PWM Individual LED Intensity Control

S Individual LED Blink Rates and Common LED

Fade In/Out Rates from 256ms to 4096ms

S FIFO Queues Up to 16 Debounced Key Events

S User-Configurable Key Debounce (9ms to 40ms)

S Keyscan Uses Static Matrix Monitoring for Low

EMI Operation

S +1.62V to +3.6V Operation

S Monitors Up to 64 Keys

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 Key-Switch Interrupt (INTK) on Each Debounced

Event/FIFO Level, or End of Definable Time Period

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.

S Port Interrupt (INTI) for Input Ports for Special-Key

Functions

S 400kbps, +5.5V Tolerant 2-Wire Serial Interface

with Selectable Bus Timeout

S Four I²C Address Choices
