I2C Slave to AHB Bridge IP

Design IP

Overview

SmartDV’s I2C Slave to AHB Bridge IP is a silicon-proven solution designed to seamlessly interface low-speed I2C-based peripherals with high-performance AHB-based systems. Ideal for embedded applications requiring reliable and efficient communication between control interfaces and system buses, this bridge ensures smooth protocol translation with minimal latency and overhead.

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.

Benefits

Seamless Protocol Bridging – Provides a direct interface between an I²C Slave and AMBA AHB bus, enabling smooth communication between low-speed peripherals and high-performance system buses
Flexible Addressing and Data Handling – Supports both 7-bit and 10-bit addressing modes, general call handling, and programmable addressing for easy integration into multi-slave systems
High-Speed Operation – Compliant with 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) I²C modes
Efficient Bus Access – Translates I²C commands into AHB transactions, supporting single and burst transfers for improved throughput and reduced latency
Robust Error Management – Handles ACK/NACK signaling, clock stretching, and arbitration loss recovery to ensure reliable data exchange between interfaces
Optimized for SoC Integration – Fully compatible with AMBA AHB master/slave protocols, designed for quick integration in SoCs requiring an I²C-based control interface to system memory or registers

Compliance and Compatibility

Fully compliant with NXP I²C-bus Specification and User Manual (UM10204)
Conforms to AMBA AHB Specification
Compatible with all major EDA synthesis, simulation, and linting flows
