How Does The DIGI POT 13 Click Board™ Work?
The DIGI POT 13 Click Board™ is based on the MAX5419, a 256-tap non-volatile digital potentiometer from Analog Devices. It can perform as a discrete potentiometer or variable resistor. The potentiometers consist of a resistor array with 255 fixed resistor elements in series between appropriate H and L terminals. The potentiometer wiper (W) terminal is programmable to access any one of the 256 tap points on the resistor string, with typically 325 ohms of wiper resistance and 150-250kΩ of end-to-end resistance (200kΩ typical). It also features a power-on reset circuitry that loads the wiper position from non-volatile memory at power up. The memory is guaranteed for 50 years for wiper data retention and up to 200.000 wiper store cycles.
The DIGI POT 13 Click Board™ communicates with the host MCU using the standard I2C 2-Wire interface, with a maximum clock frequency in Fast data transfer of up to 400KHz (400kbps). The I2C address can be selected via the ADDR SEL jumper with 0 selected by default. Over the I2C interface, all data can be stored in an internal 8-bit EEPROM.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
