MAX7360 - Key-Switch Controller And LED Driver/GPIOs

General Description

The MAX7360 peripheral provides microprocessors 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.

Key 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. 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 maxi.

19-4566; Rev 0; 4/09 www.DataSheet4U.com TION KIT EVALUA BLE A IL A AV I2C-Interfaced Key-Switch Controller and LED Driver/GPIOs with Integrated ESD Protection General Description The MAX7360 peripheral provides microprocessors 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. 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.
