MAX7365  
1MHz I2C-Interfaced 8 x 7  
Key-Switch Controller with GPIO Ports  
General Description  
Benefits and Features  
The MAX7365 is an I2C-interfaced peripheral that pro-  
vides microprocessors with management of up to 56 key  
switches.  
S Reduce Processor Load  
Monitor Up to 56 Keys  
FIFO Queues Up to 16 Debounced Key Events  
Hardware Interrupt at the FIFO Level or at the  
End-of-Definable Time Period  
Key codes generated for each keypress and release  
enable easier implementation of multiple key entries. Key  
inputs monitored statically, not dynamically, ensure low-  
EMI operation. The switches can be metallic or resistive  
(carbon) with up to 5kI of resistance.  
S Increased Battery Life  
Autosleep and Autowake Minimize Current  
Consumption  
Less Than 1µA Sleep Current  
The device features autosleep and autowake to further  
minimize the power consumption of the device. The  
autosleep feature puts the device in a low-power state  
(1FA typ) after a programmable sleep timeout period.  
The autowake feature configures the device to return to  
normal operating mode from sleep upon a keypress.  
S Save Board Space  
Small (2mm x 2mm) and Low-Profile 25-Bump  
WLP  
S Flexible Design Requirements  
1.62V to 3.6V Operation  
The key controller debounces and maintains a FIFO of key-  
press and release events (including autorepeat, if enabled).  
An interrupt (INT) output can be configured to alert key-  
presses either as they occur or at the maximum rate.  
Proprietary Ghost-Key Detection and Removal  
Key Debounce Time User Configurable from  
1ms to 31ms  
Low-EMI Design Uses Static Matrix Monitoring  
Five Additional GPIO Ports  
All Key Switches Can Be Used as GPIs  
1Mbps, 5.5V Tolerant, Two-Wire Serial Interface  
Selectable Two-Wire, Serial-Bus Timeout  
Unused key switches can be used as GPI. In addition,  
there are five additional general-purpose input/output  
(GPIO) ports. GPOs can be programmed as push-pull  
or open-drain to high- or low-side output drivers. When  
programmed as open drain, an optional on-chip 100kI  
pullup/pulldown resister can be enabled.  
The device is available in a small (2mm x 2mm) 25-bump  
wafer-level package (WLP) for cell phones, pocket PCs,  
and other portable consumer electronic applications.  
The device operates over the -40NC to +85NC extended  
temperature range.
