CD1020 Datasheet 22-channel Multiple Switch Detection Interface

Manufacturer: NXP Semiconductors

Overview: CD1020 22-channel multiple switch detection interface Rev. 5 — 20 August 2024 Product data sheet 1.

General Description

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).
