2-Wire Interfaced Low-EMI Key Switch  
and Sounder Controllers  
8/MAX7349  
General Description  
Features  
The MAX7347/MAX7348/MAX7349 I2C interfaced periph-  
erals provide microprocessors with management of up to  
64 key switches. Key inputs are monitored statically, not  
dynamically scanned, to ensure low-EMI operation. 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 1kΩ.  
♦ 400kbps, 5.5V-Tolerant 2-Wire Serial Interface  
♦ 2.4V to 3.6V Operation  
♦ Monitor Up to 64 Keys (MAX7349),  
40 Keys (MAX7348), or 24 Keys (MAX7347)  
♦ FIFO Queues Up to 8 Debounced Key Events  
♦ Key Debounce Time User Configurable from 9ms  
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.  
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  
♦ Up to Six Open-Drain Logic Outputs Available  
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.  
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  
♦ Selectable 2-Wire Serial Bus Timeout  
Applications  
♦ Under 10µA Shutdown Current
