Overview

The Improved Inter Integrated Circuit (I3C) is part of a group of communication protocols defined by the MIPI Alliance. This specification is developed to ease sensor system design architectures in mobile wireless products by providing a fast, low cost, low power, two-wire digital interface for sensors.

The MIPI I3C Master Controller is a digital core that implements all protocol functions related to Main Master, Which as defined in the MIPI I3C Specification. The MIPI_I3C Core provides an interface between the system (application) and the I3C Interface, allowing the communication with the I3C devices and Legacy I2C devices (slaves) with limitations as specified in MIPI I3C Specification.

The Dual Role MIPI_I3C Controller can be configured as I3C Main Master or I2C Master/Slave with the processor interface (ICB). The controller meets the requirement of I3C protocol and I2C protocol as specified by the MIPI I3C Specification.

Key features

  • Two Wire I3C serial interface - consists of a serial data line (SDA) and a serial clock (SCL)
    • Only support the role of Main Master, which sends the majority of the I3C Commands(CCC),
    • addressing either all Slaves(Broadcast CCCs) or specific individual Slaves(Directed CCCs)
  • Only Single Data Rate messaging (SDR)
    • Broadcast message, which are sent to all I3C Slaves on the Bus
    • Direct message, which are addressed to specific Slaves
  • Clock Stalling support in Master Mode
  • Hardware assisted Dynamic Address Assignment (DAA)
  • Detects arbitration loss due to incoming IBI and subsequently re-transmits the command
  • In-Band Interrupt(without Payload) Processing
  • Support DMA access for multi-buffer data communication
  • FIFO size for RX and TX configurable at RTL level
  • The Whole I3C Controller Design is Sync with one clock domain: ICB_CLK

From I2C to I3C: Evolution of Two-Wire Communication in Embedded Systems

The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a simple two-wire interface for synchronous, multi-master/multi-slave, single ended serial communication. Fast forward 45 years to today and it is still widely used for attaching low speed peripheral Integrated Circuits (ICs), processors and microcontrollers. But silicon today has changed...

Maximizing the Usability of Your Chip Development: Design with Flexibility for the Future

Early in my career selling chips for Motorola Semiconductor, the ability to spin derivative microcontroller chips for a customer’s specific requirement was relatively straightforward. If the volume looked reasonable, we would tape-out a new chip with a few added features because mask costs and wafers were relatively inexpensive at the larger process nodes. The customer won by getting an MCU tailored to their specific need, and Motorola won by gaining a more committed customer plus another SKU that could be sold to other customers – boosting ROI. With the migration to higher cost FinFET nodes, those times are long gone as the economics no longer work.

MIPI CCI over I3C: Faster Camera Control for SoC Architects

Imagine a camera subsystem that responds in microseconds, consumes less power, and offers a more straightforward route to time-to-market. For SoC architects and IP integration teams, that vision is increasingly possible with MIPI Camera Control Interface (CCI) over I3C.
