This paper presents a comprehensive exploration of an Field Programmable Gate Array (FPGA) prototype designed for efficient data acquisition from Micro Electro Mechanical Systems (MEMS) microphones through a Time Division Multiplexed (TDM) interface. The primary focus lies in the seamless integration of software and hardware elements, showcasing the implementation of IP cores for controlling TDM peripherals, generating clock signals, and facilitating communication with the Future Technology Devices International (FTDI) chip. The paper underscores the flexibility of the device design, which can be seamlessly deployed across various FPGA boards, thereby mitigating dependency on specific hardware models. Leveraging a large number of GPIO pins on the FPGA board, the PCB design incorporates multiple TDM buses and efficient communication channels with the FTDI chip, streamlining data transfer to the PC. This work not only presents a functional prototype but also lays the groundwork for future advancements in FPGA-based sound acquisition systems, promising enhanced versatility and efficiency in audio signal processing applications.
