CD1020 Datasheet (NXP) - 22-channel multiple switch detection interface

CD1020, 22-channel multiple switch detection interface

The CD1020 is a cost-optimized switch detection interface device (MSDI) designed to detect the closing and opening of up to 22 switch contacts.

The switch status, either open or closed, is transferred to the microprocessor unit (MCU) through a Serial Peripheral Interface (SPI).
