Keyfob PIC Programmer Multipack

Keyfob PIC Programmer Multi-Pack

Replacement units only without 12V VPP generator

A Pack of 5 individual keyfob PIC programmers for In System Programming of PIC flash microcontrollers in PIC16F and PIC18F families. Ideal for field and production programming. Each PIC programmer comes in a key fob case and has one button operation to eliminate operator errors. Removes the need for a PC on the production line or in the field.

This Multi-Pack deal gives you big savings.
Just load using the parallel port Keyfob PIC Programmer Starter Kit Once the Keyfob PIC programmer is loaded, just keep plugging it into your target boards and program/verify Flash and EEPROM with a single button press.

PIC microcontroller Support

The PIC Keyfob Programmer does not power target, so it is not suitable for all applications - please see Limitations section below.

PIC18F microcontrollers
All released PIC18F devices except J and K series.
The PIC Keyfob Programmer does not support PIC18FxxJxx or PIC18FxxKxx microcontrollers.
For support for J and K series please see Handheld PIC Programmer

PIC16F microcontrollers at 5V only
See Handheld PIC Programmer for low voltage support

Limitations

As the Keyfob PIC programmer draws power from the target circuit, it operates at the target voltage, down to 3V. However, the BULK ERASE command on the PIC microcontrollers will not work below 4.5V. So, if your target voltage is below 4.5V locked devices cannot be re-programmed. PIC16F microcontrollers need at least 4.5V in all cases. We recommend the Handheld PIC programmer for low voltage applications as it can power the target.

The maximum code size is 64KB. For larger devices, please use handheld PIC Programmer, which has a maximum code size of 256KB.

In HVP mode, because this programmer cannot power target, it cannot do VPP voltage first programming method. This means that, if the configuration bits are set for internal master clear and internal oscillator, the PIC microcontroller will start to execute code before entering the program mode because the MCLR pin will not hold it in reset. Also, if RB6 and/or RB7 are configured as outputs by the program there may be contention between these pins and the PIC programmer preventing the device from entering the program mode properly.

The keyfob is limited to 12V VPP. This means that it cannot program new PIC microcontroller families with 9V VPP, such as PIC18FxxKxx and PIC16F72x.

The Keyfob PIC Programmer is NOT designed to cope with faulty target boards, so you should test or isolate target boards first, or use the Handheld PIC Programmer instead.
