NXP Semiconductors CD1030
The CD1030 is designed to detect the closing and opening of up to 33 switch contacts. The switch status, either open or closed, is transferred to the microprocessor unit (MCU) through a serial peripheral interface (SPI). This SMARTMOS device also features a 35-to-1 analog multiplexer for reading the input channels as analog inputs.| Part No. | CD1030 |
