General Description

The MI2CMS macro implements a synchronous single-chip I2C Master and Slave Macro capable of linking one CPU to one I2C-bus. Communication with I2C-bus is carried out on a byte-wise basis using interrupt or polled handshake. It controls all I2C-bus specific sequences, protocol, arbitration and timing. The I2C macro interface allows the parallel-bus microprocessor to communicate bidirectionnally with the I2C-bus.This macro can be customized according to specific needs (application-specific requirement). Any other pre-designed functions can be integrated into the FPGA. FPGA density and I/O requirements can be defined according to customer specification.
