USB PORT Module Circuit Description

Schematic Diagram and Labelling for PIC16C745 USB Controller IC

The USB PORT Module circuit is built in with PIC16C745 microcontroller chip. This chip contains

all the necessary hardware to implement USB ( Version 2.0 ) Protocol. The chip firmware takes

care of all the USB transfers and interprets the commands sent from the PC. The yellow LED ( D14 )

indicates if the USB is active.



of 26

A diode / capacitor pump circuit ( D3, D4, D5 and D6 with C2, C8, C3 and C4 ) converts the 5V

p/p square wave pulses at “Pump” to +12V DC. This voltage runs the 4050 Buffer IC. A voltage

divider at “Feedback” controls the input of the 4050 from the PIC chip. Thus a +12V / +5V signal

can be switched to the „Program‟ pin of a PIC chip to place it in or out of program mode. The

ICSPDAT ( data ) and ICSPCLK ( clock ) signals transfer the data in and out ( for verification ) of

the Programmed PIC chip.

PIC programming board

16 pin PIC Programming Kit

The 16 pin PIC Programming Kit incorporates the PIC16F819 microcontroller from Microchip

Technology Inc. (USA). As the PIC Programming Kit had built in FLASH MEMORY, program can

be applied by not taking it off. The board can be used to input/output signals, switches, sound,

LED's, transistor drives, relays, serial port data etc. Many configurations are possible.

Fast Program Run Time - Execute at 2,000,000 instructions per second

2 Kilobyte Instruction space - Can store 2048 instructions

16 Digital Inputs/Outputs - Can be used in a variety of configurations (Port A = 8

Input/Output bits, Port B = 8 Input/Output bits)

4 Driver Outputs (B4, B5, A6, A7) - Can support up to 0.6 Amp

4 of Port A Digital Inputs/Outputs can also be set to Analog Inputs/Outputs voltage (A0, A1,

A2, A3)

Separate power supply

Built in LED indicator (B7)

Built in push button/reset button (A5)
