FAQs
What is PCA9555PW,118?
The PCA9555PW,118 is an 16-bit I2C-bus I/O expander designed by NXP Semiconductors. It is suitable for applications requiring additional GPIO (General Purpose Input/Output) pins, such as LED dimming, relay control, and keypad scanning.
How Does PCA9555PW,118 Work?
The PCA9555PW,118 works by expanding the number of GPIO pins available to a microcontroller through the I2C-bus interface. It allows for flexible digital input and output configuration, providing increased functionality without the need for additional pins on the microcontroller.
How Many Pins does PCA9555PW,118 have and What are the Functions of the Pinout Configuration?
The PCA9555PW,118 is housed in a 24-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:
- VCC: Supply voltage pin.
- GND: Ground pin.
- SCL, SDA: I2C-bus serial clock and data pins, respectively.
- P0-P7: I/O pins for Port 0 to Port 7.
- INT: Interrupt output pin.
- RESET: Reset input pin.
What are the Pros and Cons of PCA9555PW,118?
Pros:
- Increased GPIO: Provides additional I/O pins for enhanced functionality.
