Overview
The I2C is a two-wire, bi-directional serial bus, which provides a simple and efficient method of short distance data transmission between many devices. The DI2CSB provides an interface between a passive target device e.g. memory, LCD display, pressure sensors etc. and an I2C bus. It can work as a slave receiver or as a transmitter - depending on the working mode, determined by the master device. A very simple interface, composed with read, write and data signals, allows easy connection to target devices. The core does not require any programming and is ready to work after power up/reset. The read, write, burst read, burst write and repeated start transmissions are automatically recognized by the core. The core incorporates all features required by the I2C specification. The DI2CSB supports the following transmission modes: Standard, Fast and High Speed.
The DI2CS is a technology independent design which can be implemented in a variety of process technologies.

This article focuses on the most important details of the modern SPI interfaces, which are improved by many useful features. But to start, let us discover the history of the modern SPI interface, because even the old, most basic SPI interfaces are still in use.
D32PRO is one of the newest 32-bit CPUs available on the market. It’s been designed by Digital Core Design, IP Core provider and SoC design house from Poland, responsible e.g. for the world’s fastest or world’s smallest 8051 CPU. DCD launched more than 70 different architectures since 1999, which have been implemented in more than 300 000 000 electronic devices, that’s why one can be sure that quite considerable experience stands behind the D32PRO.
