The PCA9501PW,118 from NXP Semiconductors is an 8-bit I/O expander designed for general-purpose input/output expansion. It includes an on-board 2-kbit EEPROM for storing diagnostic data or board manufacturing information.
This device supports the I2C-bus and SMBus interface logic, allowing communication at clock frequencies up to 400 kHz. It operates within a voltage range of 2.5 V to 3.6 V and features an active-low open-drain interrupt output. The PCA9501PW,118 has six address pins, enabling up to 64 devices to share the bus. It is supplied in a 20-TSSOP package suitable for surface mounting.
Key features include independent assignment of I/O pins as inputs or outputs, noise filters on SCL/SDA inputs, and support for hot insertion. The device powers up with all channels configured as inputs. ESD protection exceeds 2000 V HBM, and latch-up testing exceeds 100 mA.
Applications for the PCA9501PW,118 include board version tracking, board health monitoring, and multi-card systems in telecom and networking infrastructure. It serves as a replacement for the PCF8574, offering integrated EEPROM functionality.
