... Datasheet General Description The AS1507 is a linear, dual 256-tap digital potentiome- ter specifically designed to replace discrete/mechanical potentiometers and is ideal for applications requiring a low-temperature-coefficient variable resistor. The device is controlled via a 3-wire SPI-compatible interface and features an internal EEPROM for storing wiper positions. Several device variants are available differentiated by ...

... Note: Integrated power-on reset circuitry loads the wiper position from the EEPROM at power-up. Digital Interface The AS1507 uses an SPI-compatible 3-wire interface for command settings of the device consisting of two input sig- nals (chip-select - CSN, and data clock - SCLK) and one bi-directional data pin (SDIO). Driving CSN low enables serial interface and the command/data are passed into the device synchronously by each SCLK rising edge ...

... Power-Up The AS1507 contains an integrated power-up circuit. At power up, the data are transferred from the non-volatile mem- ory to the wiper register. The wiper register moves to the stored position. This data transfer takes 5µs after the supply has reached the POR trigger level. ...

... With the next falling edge of CSN the SDIO pin is set to an input pin again. Read Wiper Register The AS1507 features the capability to read the data from the wiper register via the SPI interface page 13). This command can be implemented 16-bit command. The SDIO pin is a bi-directional pin. During the CSN low phase of the sequence, the SDIO pin is used as input pin to set the command byte ...
