NXP MC33CD1020AESR2

汽车，多开关检测SPI3 伏 ~ 5.25 伏，6 伏 ~ 36 伏表面贴装，可润湿侧翼

Overview

The MC33CD1020AESR2 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 low-cost MSDI is available in high power, space-saving wettable flank 5x5mm QFN package.
