Product Details:
Overview
The CY8C9520A-24PVXIT is an I²C expander IC manufactured by Cypress Semiconductor Corp. This device provides additional I/O ports via the I²C communication protocol, operating at a maximum clock frequency of 100 kHz. It is supplied in a 28-pin SSOP (Shrink Small Outline Package) for surface mount assembly.
Key Features
- I²C interface for serial communication
- Up to 20 programmable I/O pins
- 100 kHz maximum I²C clock rate
- 28-pin SSOP package
Applications
This I²C expander is commonly used in systems requiring extended I/O capabilities beyond the limitations of the microcontroller’s native pin count. It is suitable for various control and monitoring tasks where space is constrained and remote I/O expansion is needed.
- Sensor interface expansion
- LED matrix control
- Remote switch monitoring
