Maxim Introduces the MAX7360, a Key-Switch Controller Featuring Multiple Key Press/Release Detection On Up to 64 Keys, Plus 8 Extra GPIOs/LED Drivers and Advanced ESD Protection
The MAX7360 is a key-switch controller featuring multiple key press/release detection on up to 64 keys, plus 8 extra GPIOs/LED drivers and advanced ESD protection. Individual key codes for each press and release are stored in a FIFO register to enable monitoring of multiple key-switch events. The extra GPIOs/LED drivers can be used for keypad backlighting, LED indicators, or port expansion in remote areas of the application. Additionally, the integrated ±8kV IEC Contact Discharge and ±15kV IEC Air-Gap Discharge ESD protection saves space and avoids the cost of external protection components. Providing a complete solution for keyboard control and backlighting, the MAX7360 is ideal for smartphones, cell phones, pocket PCs, and other portable consumer-electronics applications. The 8 GPIOs/LED drivers feature constant current and individual port-intensity adjustment through a 256-step PWM control. Two of these I/Os can be configured to decode inputs from a rotary switch, for which separate debounce and interrupt conditions are used…
