EM6420 datasheet, interface equivalent, EM Microelectronic

Features and benefits

* Up to 16 analogue sensor inputs
* User selectable communication interfaces : 4-wire SPI, I2C, 4-bit parallel interface and 8-bit direct output
* User-select.

Application

where sensors are tightly spaced. It compares relative levels among sensors and selects the sensor with the largest sign.

Description

The EM6420 is an ultra low power Touch Sensor Interface IC able to scan sequentially up to 16 capacitive sensors. The device parameters (number of used sensors, sensors scan frequency, sensors sensitivity level, IRQ condition) are configurable either.
