I/O Expanders onsemi PCA9535ECDWR2G Overview
The I/O Expanders onsemi PCA9535ECDWR2G is a high-performance, 16-bit I/O expander that greatly enhances the functionality of microcontroller systems that are limited by the number of I/O ports available. This versatile component, housed in a compact 24-SOIC package, offers an ideal solution for expanding I/O capabilities using a two-wire I²C bus. By using the PCA9535ECDWR2G, designers can add additional ports with minimal wiring, greatly simplifying the design and development of a wide array of electronics systems. This makes the device particularly suitable for applications where space and I/O resources are limited, providing a cost-effective method for system expansion and integration.
PCA9535ECDWR2G Features
The PCA9535ECDWR2G by onsemi boasts a wide range of features that make it an indispensable tool for expanding I/O capabilities. Key features include:
- 16-bit I/O port expander which can operate on a 2.3V to 5.5V supply.
- I²C-bus interface supporting multiple bus speeds including 100 kHz, 400 kHz, and 1.7 MHz.
- Low stand-by current consumption, ideal for power-sensitive applications.
- 25 mA sink capability for outputs and 400 mA of maximum output current which allows direct driving of LEDs.
- Enhanced robustness with built-in power-on reset and 8 kV ESD protection.
- Programmable polarity inversion register to configure the polarity of the input port data.
PCA9535ECDWR2G Applications
- Automotive Infotainment Systems: Employed to expand the number of controls and buttons without needing additional microcontroller pins.
- Industrial Automation: Used in complex machinery to add more sensors and actuators through a single microcontroller.
- Home Automation Systems: Facilitates the addition of more input/output options for enhanced control over home devices.
- Server Farms: Useful in managing multiple server inputs/outputs through centralized control units.
- Mobile Devices: Expands the I/O capabilities of compact devices such as smartphones and tablets.
