The NXP Semiconductors PCA9501D,112 is an 8-bit I/O expander designed for board-level status monitoring and control. It integrates a 2-kbit EEPROM for storing diagnostic data such as error codes or manufacturing information.
This device supports the I2C-bus and SMBus interface logic, allowing communication at clock frequencies up to 400 kHz. It features eight quasi-bidirectional data pins that can be independently configured as inputs or outputs. An active-low interrupt output signals the system master when an input state changes.
With six address pins, up to 64 devices can share the I2C-bus. The PCA9501D,112 operates within a voltage range of 2.5V to 3.6V and has 5V tolerant inputs/outputs. It is supplied in a 20-SOIC surface-mount package and operates within a temperature range of -40°C to 85°C.
Key features include hot insertion support, making it suitable for removable card systems. The device also includes internal pull-up resistors, noise filters on SCL/SDA inputs, and a power-on reset function. It is a replacement for the PCF8574, offering integrated EEPROM functionality.
