EM6420
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 from a host microcontroller through a munication port or through configuration inputs.
Key Features
- Up to 16 analogue sensor inputs
- User selectable munication interfaces: 4-wire SPI, I2C, 4-bit parallel interface and 8-bit direct output
- User-selectable active edge IRQ output signal
- Active high enable input
- No software development and tuning required
- Development tools and documentations available
