MC33CD1030AER2 Description

Short technical summary and product information.

The NXP Semiconductors MC33CD1030AER2 is a specialized interface IC designed for detecting the status of up to 33 switch contacts. It communicates with a microprocessor unit (MCU) via a serial peripheral interface (SPI).

This device offers a wide operating voltage range from 4.5 V to 36 V, with full parametric operation between 6.0 V and 28 V. It supports switch input voltages from -1.0 V to 36 V and includes selectable wetting currents ranging from 2.0 mA to 20 mA, with programmable pulse or continuous operation. The IC also features a 35-to-1 analog multiplexer for reading input channels as analog signals, including battery voltage and die temperature monitoring.

Available in a 48-LQFP Exposed Pad package, the MC33CD1030AER2 is suitable for surface mount applications. It includes various operating modes such as Normal, Low-power (LPM), and Polling modes, making it ideal for automotive and industrial products requiring low sleep-state currents. An active interrupt pin signals changes in switch states.
