【Abstract】 A multi-MPU supporting MPU interface circuit which is applied mainly in STN LCD Driver is designed in the paper. The circuit supplies data and timing control for the whole chip, and it firstly supports I2C bus protocol in the congeneric design. The requirement of the circuit is briefly introduced, and the analysis and design of each block in the circuit are described in detail. The Verilog Hardware Description Language (VHDL ) is used to verify the function of this circuit. The whole chip is implemented in SMIC’s 0.25 μm technology.更多还原
