DESCRIPTION

· The CY8C95xxA is a multi-port I/O expander with onboard user-available EEPROM and several PWM outputs.
· It operates as two I2C slave devices: a multi-port I/O expander and a serial EEPROM.
· The device supports up to 20, 40, or 60 I/O data pins, configurable as inputs, outputs, or PWM outputs.
· It includes internal EEPROM for user default storage and I/O port settings.
· The device supports I2C interface logic compatible with SMBus.

FEATURES

· I2C interface logic electrically compatible with SMBus.
· Up to 20, 40, or 60 I/O data pins independently configurable as inputs, outputs, or PWM outputs.
· 4/8/16 PWM sources with 8-bit resolution.
· Extendable soft addressing algorithm for flexible I2C address configuration.
· Internal 3-/11-/27-Kbyte EEPROM.
· User default storage and I/O port settings in internal EEPROM.
· Optional EEPROM write disable (WD) input.
· Interrupt output for input pin level changes and PWM state changes.
· Internal power-on reset (POR) and configurable watchdog timer.

APPLICATIONS

· Industrial control systems requiring multiple I/O expansions.
· Consumer electronics for PWM control and I/O management.
· Embedded systems needing configurable I/O and EEPROM storage.
· Automotive applications for sensor interfacing and control.
· IoT devices requiring flexible I/O and PWM configurations.
