Product Details
Serial I/O Expanders, Cypress Semiconductor
Multi-port I/O expanders from Cypress Semiconductor with on-board user accessible EEPROM and several PWM outputs.
I2C interface logic electrically compatible with SMBus
Up to 20 (CY8C9520A), 40 (CY8C9540A), or 60 (CY8C9560A) I/O data pins independently configurable as inputs, outputs,Bi-directional input/outputs, or PWM outputs
4/8/16 PWM sources with 8-bit resolution
Extendable soft addressing algorithm allowing flexible I2C address configuration
Internal 3-/11-/27-Kbyte EEPROM
User default storage, I/O port settings in internal EEPROM
Optional EEPROM write disable (WD) input
Interrupt output indicates input pin level changes and pulse width modulator (PWM) state changes
Internal power on reset (POR)
Internal configurable watchdog timer
