Hardware DescriptionThe I2C Port Expander Evaluation Kit allows you to easily assess the following value propositions of Cypress' I2C port expander solutions:

       

• Integration       
  
• Flexibility       
  
• Compatibility
  

Cypress' three I2C port expander devices (CY8C9520, CY8C9540, CY8C9560) have the following features:

       

• Three compatible part families that seamlessly scale up or down       
  
• 20, 40, or 60 individually configurable IO (widest range of IOs in the industry)       
  
• 4, 8, or 16 PWMs that map to any pin or multiple pins (Widest range of PWMs in the industry)       
  
• 3 Kbytes, 11 Kbytes, or 27 Kbytes of User EEPROM (largest amount of user-accessible serial EEPROM in the industry)       
  
• I2C communication up to 400 kHz       
  
• Industrial temp range: -40 to 85 degrees Celsius       
  
• Operating voltage: 3.0V - 5.25V       
  
• 28-SSOP/48-SSOP/100-TQFP package options
  

Bottom line: One Cypress I2C Port Expander device replaces multiple port expander ICs from other vendors and flexibly integrates IO expansion, PWM functions and user EEPROM.
This kit also includes the I2C-USB Bridge, which allows hardware and software debugging of PSoC applications by seamlessly connecting your PC's USB port to your application's I2C interface.
