Avalon compliant I2C Master IP core provides an interface between Nios® II processor and an I2C Slave device. It can work as a master transmitter or master receiver depending on working mode determined by Nios II processor. The I2C Master IP core incorporates all features required by the latest I2C specification including clock synchronization, arbitration, multi-master systems and fast-speed transmission mode.The I2C Master IP core is provided as Intel® Platform Designer (formerly Qsys) ready component and integrates easily into any Platform Designer generated system.
Features
- Clock stretching and wait state generation, Software programmable acknowledge bit
- Interrupt or bit-polling driven byte-by-byte data-transfers, Arbitration lost interrupt, with automatic transfer cancellation
- Start/Stop/Repeated Start/Acknowledge generation and detection, Bus busy detection, Supports 7 and 10bit addressing mode
- Two transmission speeds are supported; Normal: 100Kbps Fast: 400Kbps
- Compatible with Philips I2C standard, Multi Master Operation, Software programmable clock frequency
