They have photographed that very carefully so you cannot read the part number but I am guessing its https://www.sparkfun.com/products/8125
For me I can buy the board from velleman for the same price as the chip...

From the DS its saying that the chip can work without an MCU. The relevant webpage says it can be used to build a stand-alone mp3 player. If there is an SPI EEPROM that is, which I can't see on your picture although there is a site for it on the PCB.
So perhaps the chip is a Chinese copy of the VLSI part. My eyesight isn't good enough but it may be the same part as used in this Chinese player which is also functioning without any external memory.

What do you find scary about Chinese mp3 modules? I have several of these stupidly cheap players, they work fine. Sound quality on mp3 isn't great, some background noises but on .wav that goes away : https://item.taobao.com/item.htm?spm=a230r.1.14.222.EHeiEe&id=20171661382&ns=1&abbucket=13#detail
