Introducing the NXP PCA9501PW,118

The PCA9501PW,118 is a sophisticated 8-bit I/O expander with an integrated EEPROM memory, brought to you by NXP Semiconductors, a leader in innovative high-performance mixed-signal products. This versatile component is designed to operate with a 2-wire I²C-bus/SMBus, offering a seamless solution for expanding I/O capabilities in microcontroller-based systems where additional inputs/outputs are needed.

Key Features

• 8-bit I/O Expander: Provides additional eight I/O pins that can be configured as inputs or outputs, allowing for enhanced control over your electronic designs.
• Integrated EEPROM: Comes with 256 bytes of EEPROM memory that can be used to store user-defined data, which is accessible through the I²C-bus interface.
• I²C-bus/SMBus Interface: Offers compatibility with the I²C-bus standard, supporting both 100 kHz (Standard-mode) and 400 kHz (Fast-mode) data transfer rates.
• Programmable Polarity Inversion: Input port polarity is programmable through the I²C-bus, allowing for flexibility in handling signal inversion without additional hardware.
• Power-On Reset: The I/Os default to inputs with a high-impedance state, ensuring a safe startup phase for your system.
• Built-in Oscillator: The on-chip oscillator reduces external component count and simplifies circuit design.
• Low Standby Current: Optimized for low-power consumption, making it suitable for battery-operated devices.
