The core is also suitable for implementing controllers for the Power Management Bus (PMBUS). The core can be programmed to operate either as a bus master or a slave, and it is easy to program and integrate. An arbitration mechanism allows operation in a multiple master bus and the SMBus provisioned clock synchronization mechanism allows fast-master/slow-slave communication. Furthermore, the core detects timeout and errors to prevent bus deadlocks, and can filter out glitches on the serial line. The control, status, and data registers of the I2C-SMBUS core are accessible via an AMBA APB or a generic memory mapped interface. The I2C-SMBUS is a microcode-free design developed for reuse in ASIC and FPGA implementations. The design uses rising-edge-triggered flip-flops only with the reset type (i.e. asynchronous and/or synchronous) being configurable at synthesis time. Furthermore, the core does not use tri-states; therefore scan insertion is straightforward.

It can operate as a bus master or slave, with simple programming and easy integration. An arbitration mechanism enables use in multi-master systems, while SMBus clock synchronization supports fast-master/slow-slave communication. The core prevents deadlocks by detecting timeouts and errors and includes glitch filtering on the serial line. Control, status, and data registers are accessible via AMBA APB or a generic memory-mapped interface. Designed for reuse in ASIC and FPGA implementations, it is microcode-free and uses only rising-edge-triggered flip-flops with configurable reset types. The design avoids tri-states, ensuring straightforward scan insertion and efficient implementation in embedded systems. Partner Solutions
