PCA9561 Datasheet (NXP Semiconductors) - Quad 6-bit multiplexed I2C EEPROM DIP switch

PCA9561, Quad 6-bit multiplexed I2C EEPROM DIP switch

The PCA9561 is a 20-pin CMOS device consisting of four 6-bit non-volatile EEPROM registers, six hardware pin inputs and a 6-bit multiplexed output.

It is used for DIP switch-free or jumper-less system configuration and supports Mobile and Desktop VID Configuration, where five preset values (four set
