What is I2C logic?
What is I2C logic?
I2C (Inter-Integrated Circuit, eye-squared-C), alternatively known as I2C or IIC, is a synchronous, multi-controller/multi-target, packet switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductors.
What are the four I2C modes of operation?
The I2C module may be configured to operate in the following modes: I2C slave, 7-bit addressing, I2C slave, 10-bit addressing, and. I2C master, 7- or 10-bit addressing.
Is I2C wired?
I2C requires a mere two wires, like asynchronous serial, but those two wires can support up to 1008 peripheral devices. Data rates fall between asynchronous serial and SPI; most I2C devices can communicate at 100kHz or 400kHz.
What is an I2C device?
I2C is a serial protocol for two-wire interface to connect low-speed devices like microcontrollers, EEPROMs, A/D and D/A converters, I/O interfaces and other similar peripherals in embedded systems. It was invented by Philips and now it is used by almost all major IC manufacturers.
Is I2C serial?
What is I2C? It is a serial communications protocol similarly to UART. However, it is not used for PC-device communication but instead with modules and sensors. It is a simple, bidirectional two-wire synchronous serial bus and requires only two wires to transmit information between devices connected to the bus.
Which company developed I2C?
Explanation: The I2C is developed by Philips for use within the television sets.
Which devices support I2C?
I2C Device List

Why is I2C needed?
In short, when you need to establish short distance communication within the same board or device, you can use I2C. It requires only two bidirectional wires for transmitting and receiving information. I2C allows designers to establish two-way communication between multiple master ICs and slave ICs.
Who developed I2C?
Philips Semiconductors
The I2C bus was developed in the early 1980’s by Philips Semiconductors. Its original purpose was to provide an easy way to connect a CPU to peripheral chips in a TV-set.
Why is it called I2C?
The research done by Philips Labs in Eindhoven (The Netherlands) to overcome these problems resulted in a 2-wire communication bus called the I2C bus. I2C is an acronym for Inter-IC bus. Its name literally explains its purpose: to provide a communication link between Integrated Circuits.
What is Inter-Integrated Circuit (I2C)?
I2C stands for Inter-Integrated Circuit. It is a bus interface connection protocol incorporated into devices for serial communication. It was originally designed by Philips Semiconductor in 1982. Recently, it is a widely used protocol for short-distance communication. It is also known as Two Wired Interface (TWI).
Why do we call i2c a two-wire communication protocol?
Because in I2C we used two wires for the communication so generally, people call it a two-wire communication protocol. In which one wire is used for the data (SDA) and the other wire is used for the clock (SCL). You should know that I2C is a half-duplex protocol.
How does clock synchronization work in I2C?
In the I2C, this clock synchronization is done by wired and logic. Let’s see an example for a better understanding, where two masters try to communicate with a slave. In that situation, both masters generate their own clock signal, master M1 generates clk1 and master M2 generates clk2, and the clock observed on the bus is SCL.
How does I/O work in I2C?
I2C can use even slower microcontrollers with general-purpose I/O pins since they only need to generate correct Start and Stop conditions in addition to functions for reading and writing a byte. Each slave device has a unique address. Transfer from and to master device is serial and it is split into 8-bit packets.
