Description
The MAX7370 I2C-interfaced peripheral provides microprocessors with management of up to 64 key switches, with optional GPIO and PWM-controlled LED drivers.
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 (1µA typ) after a timeout period. The autowake feature configures the device to return to normal operating mode from sleep upon a keypress. The key controller debounces and maintains a FIFO buffer of keypress and release events (including autorepeat, if enabled). An interrupt (INT) output can be configured to alert keypresses, as they occur, or at the m.
