Features

• Variable Vdd supply.  The USBProg can provide Vdd power from 0 to 6 volts to accomodate PICs with different requirements and to verify the programmed data at the Vdd limits for the particular target chip. 

• 100mA Vdd drive capability to power some target circuitry along with the target chip. 

• Tolerant of over 1000µF capacitance on the target Vdd line. 

• Variable Vpp supply from 0 to 14V to accomodate many of the newer PICs that can not use the traditional 13V. 

• Vdd and Vpp readback for closed loop control and failure detection. 

• Low impedence PGC and PGD outputs.  150 ohm output drivers guarantee sharp edges, high speed operation, and can tolerate up to 200pF load at the target chip. 

• PGC and PGD lines are short circuit protected.  These lines can be tied to 0-6 volts indefinitely without damage to the programmer. 

• The target chip programming lines are available two ways:

  • RJ-12 jack with the same pinout as the Microchip ICD2. 

  • 6 pin locking header.  Two ground lines separate the PGD and PGC signals from the remaining signals for ease of making cables that prevent crosstalk. 

• For an optional means of communicating to the USBProg, TTL level serial I/O connections are available to allow for RS-232 communication with the host via an adapter (not included).  For RS-232 communication, the unit can be powered from the USB or from a separate 5V supply. 

• The target system can be run and halted from the host computer while connected to the programmer. 

• Two layer board with the bottom layer mostly a ground plane to provide good EMI properties. 

• Scriptable run time software, available via free download. 

• Host library is available for free download.  You can create your own software to read, write, and verify the non-volatile memory of PICs using the supplied API. 

• Open source. 

• Open specification.  You can create your own software for any system that has a standard USB or serial port.
