2-Wire Interfaced Low-EMI Key Switch and

Sounder Controllers

General Description

Features

♦ 400kbps, 5.5V Tolerant 2-Wire Serial Interface

♦ 2.4V to 3.6V Operation

The MAX7347/MAX7348/MAX7349 I²C* interfaced

peripherals provide microprocessors with management

of up to 64 key switches. Key inputs are monitored stati-

cally, not dynamically scanned, to ensure low-EMI opera-

tion. The MAX7347 can monitor up to 24 switches, the

MAX7348 can monitor up to 40 switches, and the

MAX7349 can monitor up to 64 switches. The switches

can be metallic or resistive (carbon) up to 5kΩ.

♦ Monitor Up to 64 Keys (MAX7349AEG,

MAX7349ATG+), 40 Keys (MAX7348AEP), or 24

Keys (MAX7347AEE)

♦ FIFO Queues Up to 8 Debounced Key Events

The key controller debounces and maintains a FIFO of

key-press events (including autorepeat, if enabled). An

interrupt (INT) output can be configured to alert key

presses either as they occur, or at maximum rate.

♦ Key Debounce Time User Configurable from 9ms

to 40ms

♦ Key Autorepeat Rate and Delay User Configurable

♦ Low-EMI Design Uses Static Matrix Monitoring

The MAX7348/MAX7349 feature a tone generator to

generate automatic key-click sounds or alarm tones

under processor control.

♦ Hardware Interrupt on Each Debounced Event or

FIFO Level, or at End of Definable Time Period

The sounder frequencies cover the 5th musical octave

(523.25Hz to 987.77Hz), plus seven other musical

notes up to 2637Hz. The output can also be pro-

grammed to be high or low for the sound duration to

operate an electronic sounder, relay, or lamp.

♦ Up to Six Open-Drain Logic Outputs Available

Capable of Driving LEDs

♦ Sounder Output Generates Automatic Key Clicks

♦ 14 Programmable Musical Sounder Frequencies

♦ Continuous or Programmable Sounder Duration

The MAX7347 is offered in 16-pin QSOP and TQFN

packages. The MAX7348 is offered in a 20-pin QSOP

package. The MAX7349 is available in 24-pin QSOP and

TQFN packages. The MAX7347/MAX7348/MAX7349

operate over the -40°C to +125°C temperature range.

♦ Easy Automatic Single-Tone and Dual-Tone Alarm

Sound Generation

♦ Four I²C Address Choices

Applications

♦ Selectable 2-Wire Serial Bus Timeout

♦ Under 10µA Shutdown Current
