Describe
1MHz I2C-Interfaced 8 x 7 Key-Switch Controller with GPIO Ports

Product Description

The MAX7365EWA70 I2C interface peripheral provides up to 56 key switch management for the microprocessor.

Each time a key is pressed or released, a key value is generated, simplifying the design of the multi-key input scheme. Adopt static key input monitoring instead of dynamic scanning mode to ensure low EMI operation. Metal switches or resistive (carbon) switches up to 5kΩ can be adopted.

The MAX7365EWA70 features automatic sleep and wake-up functions, thereby maintaining the lowest device power consumption. After one programmable sleep cycle, the automatic sleep function places the device in A low-power state (typically 1µA). When a key operation event occurs, the automatic wake-up function configuration device returns from the sleep state to the normal working mode.


Its main features include:

Reduce the load on the processor

Up to 56 keys can be monitored

The FIFO can store up to 16 debouncing key events

A hardware interrupt is generated at the end of a FIFO level or a definable time period

Extend battery life

The automatic sleep and wake-up functions minimize power consumption

The dormant current is less than 1µA

Save circuit board space

Small size (2mm × 2mm), 25 solder ball WLP package

Flexible design

Power supply range: 1.62V to 3.6V

Proprietary false key detection and removal technology

Users can configure the key to shake the time from 1ms to 31ms

Adopt a low EMI static matrix monitoring design

Five additional GPIO ports

All key switches can be used as GPI

1Mbps, 2-wire serial port compatible with 5.5V

A two-wire serial bus timeout can be selected

Due to its stable performance and easy-to-implement multi-key input function, the MAX7365EWA70 is widely used in various application scenarios, including:

Cellular phone

Handheld game console

Notebook computer

PDA

Portable consumer electronics
