Switch Detect interface, 33 channel, Mono, 48 LQFP

The CD1030 is a multiple switch detection interface (MSDI) 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 through a SPI in

automotive environments.

*

This SMARTMOS® device features a 35-to-1 analog multiplexer

for reading analog inputs.

*

The analog input signal is buffered and provided on the analog multiplexer

(AMUX) output pin for the MCU to read

*

Individually selectable input currents are available in Normal and Low-Power

Mode

*

Battery and temperature monitor are included in the IC and available via the

AMUX pin

* Interfaces with any MCU that supports SPI communications
