The LPC47N207-JV is an Integrated Circuit (IC) component manufactured by Nuvoton Technology Corporation. It is a general-purpose input/output (GPIO) expander with an I2C interface. The LPC47N207-JV is mainly used in electronic systems that require additional I/O pins.
Key Features:
1. Input/Output Pins: The LPC47N207-JV provides a total of 40 GPIO pins, which can be individually configured as input or output pins. These pins can be used to interface with various external devices, such as sensors, buttons, LEDs, etc.
2. Pin Multiplexing: The IC offers pin multiplexing functionality, allowing multiple functions to be assigned to a single pin. This feature provides flexibility and reduces the number of required pins, making it suitable for space-constrained designs.
3. I2C Interface: The LPC47N207-JV supports the widely-used Inter-Integrated Circuit (I2C) interface, allowing easy communication with other ICs and microcontrollers. It operates as an I2C slave device and can be controlled by a master device.
4. Interrupt Support: The IC supports interrupt functionality for all GPIO pins. This enables the system to be notified immediately when a change in the GPIO state occurs, reducing the need for continuous polling and conserving system resources.
5. Pull-up/Pull-down Resistors: Each GPIO pin can be individually configured with internal pull-up or pull-down resistors
