PC accessory SDRAM module controller based on LPC860 MCU

PCA-LPC860-MCU

Overview

The SDRAM module controller reference design for PC accessory applications is based on two LPC860 MCUs and utilizes an I3C interface to transmit audio spectrum and temperature information between the controller and the target. The controller uses FTM to trigger the ADC to sample the audio information, and then executes the FFT algorithm to obtain the spectrum information. After the calculation is completed, the spectral information is transmitted to the target through the I3C interface, and then the device will drive the LED matrix to display the spectral information. At the same time, the target also detects temperature information and transmits it to the controller via I3C.
