Product Overview: PCA9535CPW by NXP Semiconductors

The PCA9535CPW is a robust, high-performance 16-bit I/O expander from the industry-leading semiconductor manufacturer, NXP Semiconductors. This device is designed to provide additional I/O ports for a microcontroller or processor with a limited number of GPIOs. The PCA9535CPW is particularly useful in applications where board space is at a premium and additional I/Os are needed for switches, sensors, or other input/output devices.

Key Features:

• I/O Expansion: 16-bit I/O port expander which can be interfaced through a two-wire I²C-bus/SMBus.
• Operating Voltage: Flexible voltage range from 2.3V to 5.5V, making it suitable for interfacing with both 3.3V and 5V logic levels.
• Interrupt Output: Configurable interrupt output which can be connected to the interrupt logic of the host microcontroller to indicate an input change on the port pins.
• High-Speed I²C Interface: Supports fast I²C bus clock frequencies of up to 400 kHz.
• Polarity Inversion: Individual polarity inversion registers provide an easy way to invert the polarity of the I/O pins.
• Low Standby Current: Ideal for battery-powered applications due to its low standby current.
• Package: Available in a TSSOP-24 package, which is suitable for space-constrained applications.
