One Cypress I2C Port Expander device replaces multiple port expander ICs from other vendors and flexibly integrates IO expansion, PWM 
functions and user EEPROM. It provides integration, flexibility and compatibility to PSoC users. 
 
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 I/Os 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  
•
