Hardware Description
The CY3242-IOXLite Demo Kit quickly demonstrates 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.
