Philips Semiconductors (now NXP Semiconductors) developed a simple bidirectional 2-wire bus for efficient inter-IC control, called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL).

NXP offers a vast portfolio of I2C-bus devices that can address all your design needs from cellular handsets and LED blinkers to LCD displays

2023年8月25日 · The Inter-Integrated Circuit (I2C) protocol is a serial bus protocol that allows multiple peripheral devices to communicate to one or more master devices with a pair of control and data signals. In MCIMX8ULP-EVK9, the I2C interface is implemented through I2C buses from two I2C masters, described in I2C buses and masters .

I2C is a common way to interface a processor with a peripheral such as EEPROM, accelerometer, or communication device, and can even be used to
