Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present application is characterized in that a control chip 2 and a memory chip 4 are disposed in the carrier, the control chip is connected to the memory chip, a gold finger 3 is disposed on the bottom surface of the carrier, the control chip is connected to the gold finger, the carrier is rectangular, the length of the carrier is 14.00mm-17.00mm, and the width of the carrier is 11.00mm-12.00mm

The following electrical device models are used in the present case:

the circuit diagram of the golden finger patch part is shown in fig. 4:

PLUG1- - -USB connector (PLUG)

R1-current limiting resistor

C2-filter capacitor

Signal line function:

DM- - - - - - -USB differential signal (minus D- -)

DP- - - - - -USB differential Signal (Positive D +)

VBUS- - -USB Power input (5V)

GND-ground wire

1. 5V output by the computer USB is sent to C2 for filtering through PLUG1 and R1, and then the power is supplied to the master controller.

2. The computer sends the USB differential signal to the main control through PLUG 1;

the circuit diagram of the control chip is shown in fig. 5:

the function of the element is as follows:

MW 8209E-Master (completing the conversion between USB protocol and INFO protocol and the processing of data)

R2- -pull-down resistor (force the level of RB1 to 0)

C7-controlling the internal LDO filter capacitor.

Signal line function:

VDD1_8- -1.8V Voltage (Master internal LDO)

VDD3_3- -3.3V Voltage (Master internal LDO)

DATA0-DATA7- - -DATA line (bit0-bit7)
