CD1020 - 22-channel multiple switch detection interface

Datasheet Summary

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).

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). This SMARTMOS device also features a 22-to-1 analog multiplexer for reading the input channels as analog inputs. The analog selected input signal is buffered and provided on the AMUX output pin for the MCU to read. The CD1020 device has three modes of operation, normal mode, low-power mode (LPM), and polling mode.
