Classification of USB interface data cables: without IC; With IC; Special chips

1. Without IC: Without a central control chip, the phone and computer must be plugged in to recognize the cable, which is cheap

Typical models: Samsung CDMA series, D500 series; Motorola E398 series, V3 series; Nokia DKU-2; NEC N720 series; Siemens 65 series and so on

2. Equipped with IC: Equipped with a central control chip, the models of ordinary chips are 2303, 2101, and 3116, which can recognize cables without plugging in mobile phones and computers. Due to the price of an IC being over 10 yuan, it is more expensive than those without an IC. The working principle of a data cable with a chip is USB to COM, which converts the USB interface into a serial port and displays it on the computer

Typical models: Samsung E638 series, D418 series; NEC N610 series; Siemens 25 series, 55 series; Sony Ericsson mobile data cable; Panasonic mobile data cable; Lenovo mobile data cable and so on
