Excuse me, is there a difference between the first generation chip and the second generation chip of Southern Tyco Calendar? ,

The first generation of calendar chip: TG 2488 (this chip was put into the market in 2003. It is a multifunctional chip independently developed by our company and has language versions in many countries. A chip plus several peripheral components can realize the functions of most calendar products on the market, so that you can reduce the investment cost as much as possible. )

The second generation calendar chip: TG 25 18 (put into the market in 2004, 2518 is an upgraded version of 2488, which is completely compatible with 2488 chip and more powerful than 2488. )
