What are the key features of PCA9535EDWR2G?
- 16-bit bidirectional I2C I/O expander with 2 independent 8-bit ports and interrupt-on-change output for low-overhead GPIO expansion
- Up to 1 MHz I2C clock speed with 3-bit address configuration supporting up to 8 devices on a single 2-wire bus
- 2.3 V to 5.5 V supply range in RoHS-compliant SOIC-24 package for flexible integration into 3.3 V and 5 V embedded systems
What is PCA9535EDWR2G used for?
The PCA9535EDWR2G is ideal for expanding GPIO counts in IoT nodes, industrial PLCs, and embedded systems where I2C connectivity is already present and additional pins are needed without adding bus complexity. Its 16 configurable inputs or outputs and interrupt output reduce polling overhead, enabling efficient management of LED arrays, relay banks, and sensor enable signals. The device suits home automation gateways, industrial HMI panels, and robotics controllers where multiple GPIO-hungry peripherals share a 2-wire I2C bus.
