The PCA9501D,118 from NXP Semiconductors is an 8-bit general-purpose I/O expander featuring an on-board 2-kbit EEPROM. This device is designed for I2C-bus and SMBus interfaces, supporting clock frequencies up to 400 kHz. Each of the eight quasi-bidirectional data pins can be independently configured as an input or output.
The integrated EEPROM can store error codes or board manufacturing data for diagnostic purposes. The device includes an active-low, open-drain interrupt output that signals when an input state changes. With six address pins, up to 64 devices can share the I2C-bus. The PCA9501D,118 supports hot insertion, making it suitable for removable card systems.
Key electrical specifications include an operating voltage range of 2.5V to 3.6V and 5V tolerant inputs/outputs. It operates within a temperature range of -40°C to 85°C. The device is supplied in a 20-SOIC package with surface mount mounting type.
This I/O expander is a replacement for the PCF8574, offering integrated EEPROM functionality. It is well-suited for applications such as board version tracking, status reporting, multi-card systems, and general-purpose I/O expansion with memory.
