Slave I2C bus controller with FIFO

The DI2CS core provides an interface between a microprocessor / microcontroller and I2C bus.

Overview

The DI2CS core provides an interface between a microprocessor / microcontroller and I2C bus. It can work as:
- a slave transmitter or
- slave receiver
depending on a working mode determined by the master device. The DI2CS core incorporates all features required by the latest I2C specification, including:
- clock synchronization,
- arbitration,
- high-speed transmission mode.

The DI2CS supports all transmission speed modes:
- Standard (up to 100 kb/s)
- Fast (up to 400 kb/s)
- Fast Plus (up to 1 Mb/s)
- High Speed (up to 3,4 Mb/s)
DCD’s IP Core is a technology independent design and can be implemented in various process technologies.
