PCA9561
Overview
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 sets of internal non-volatile registers and one set of external hardware pins) set processor voltage for operation in various performance or battery conservation sleep modes.
- Selection of non-volatile register_n as source to MUX_OUT pins via I2C-bus
- I2C-bus can override MUX_SELECT pin in selecting output source
- 6-bit 5-to-1 m
