The PCA9570GM is an 8-bit I2C-bus and SMBus I/O port with interrupt. It is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C-bus interface. The device typically comes in a small, space-saving package.
The PCA9570GM is available in a 20-pin configuration. The pin functions are as follows:
- VDD: Power supply pin.
- GND: Ground reference pin.
- SDA: I2C-bus data line (bidirectional).
- SCL: I2C-bus clock line.
- INT: Interrupt output pin.
- P0 to P7: General-purpose I/O pins.
The device operates as a slave device on the I2C-bus and can be used for expanding I/O capabilities. Each of the eight I/O pins (P0 to P7) can be configured individually as either an input or an output. The interrupt output (INT) is triggered by any input change on the I/O pins, which allows the microcontroller to respond to events without continuously polling the device.
