Rochester Electronics Interface - Specialized PCA9560D,112

The PCA9560D,112 is a dual 5-bit multiplexed 1-bit latched I¬=C-bus EEPROM DIP switch designed for system configuration without the need for DIP switches or jumpers. It features two 6-bit non-volatile EEPROM registers, five hardware pin inputs, and a 5-bit multiplexed output. This device is particularly useful in applications requiring CPU VID (Voltage Identification) configuration, allowing for adjustments in processor voltage to optimize performance or reduce power consumption. The PCA9560 operates with a power supply voltage range of 3.0 V to 3.6 V and supports I¬=C/SMBus communication. It includes internal pull-up resistors and can accommodate up to four devices on the same bus due to its two address pins. The device is footprint compatible with the PCA9559, making it a suitable drop-in replacement without requiring software modifications. Additionally, it offers ESD protection exceeding 2000 V and is available in a TSSOP20 package, suitable for various applications including server and telecom/networking environments.
