The PCA9500PW,112 from NXP Semiconductors is an 8-bit I/O expander that includes an on-board 2-kbit EEPROM. This device is designed for monitoring board-level status or activating indicator devices like LEDs through its eight quasi-bidirectional data pins, which can be independently configured as inputs or outputs.
The expander utilizes the I2C-bus and SMBus interface logic, supporting a clock frequency of up to 400 kHz. It operates within a voltage range of 2.5 V to 3.6 V and features 5 V tolerant inputs/outputs. The integrated EEPROM can store diagnostic data such as error codes or board manufacturing information.
With three address pins, up to eight devices can share a common I2C-bus. The PCA9500PW,112 is a drop-in replacement for the PCF8574, offering the added benefit of integrated EEPROM. It supports hot insertion, making it suitable for removable card systems.
This component is supplied in a 16-TSSOP package and is designed for surface mount applications. Its operating temperature range is -40°C to 85°C.
