I2C Slave IP
Design IP
Overview

SmartDV’s I2C Slave IP is a silicon-proven solution for implementing Inter-Integrated Circuit (I2C) protocol slave functionality in a wide range of embedded applications. Fully compliant with the I2C specification, it enables seamless communication with I2C master devices in standard, fast, and high-speed modes.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. Ideal for sensor interfaces, peripheral controllers, and system management tasks, the I2C Slave IP offers robust performance and smooth integration into SoC and FPGA designs.

I2C Slave
Benefits
  • Reliable Two-Wire Communication – Implements the I²C protocol for efficient slave-side communication with full support for Start, Repeated Start, and Stop conditions
  • Flexible Addressing and Response Handling – Supports both 7-bit and 10-bit addressing modes, general call address handling, and clock stretching capabilities
  • High-Speed Data Transfer – Operates in Standard (100 kbit/s), Fast (400 kbit/s), Fast-Plus (1 Mbit/s), High-Speed (3.4 Mbit/s), and Ultra-Fast (5 Mbit/s, unidirectional) modes
  • Integrated Data Management – Optional in-built DMA controller for streamlined data movement between the I²C interface and system memory
  • Error Detection and Recovery – Handles ACK/NACK generation, arbitration loss, and bus error conditions with automatic recovery mechanisms
