CD1030 Datasheet 33-channel Multiple Switch Detection Interface

Manufacturer: NXP Semiconductors

Overview: CD1030 33-channel multiple switch detection interface with programmable wetting current Rev. 6.

General Description

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).
