Description
The ISPIC Adaptor enables the In Circuit programming of PIC Microcontrollers. In circuit programming
can be applied to any serially programmable part including One Time Programmable (OTP) and Flash
devices.
It consists of an adaptor which plugs into the ZIF socket of the users existing programmer (e.g.
PICSTART+, MEL EPICA etc), and connecting cable which connects to the target board (adjacent to the
PIC Micro to be programmed).
The ISPIC adaptor is shipped with a low cost Molex Picoflex flying socket (on the end of the cable). A
mating Picoflex PCB mounting plug (also supplied) is mounted on the target PCB. This provides easy
connection for the programming cable. Alternatively any custom connection can be used
Programming of a device using the ICSP technique is achieved by powering up the device and then
holding RB6 and RB7 low while raising the MCLR/Vpp pin to +13 volts. This places the PIC in
programming mode and a clock signal on RB6 is then used to clock data into, and out of RB7.
Operation
The user simply connects one end of the ISP to the standard PIC Programmer ZIF socket and the other
end to the target board containing the target PIC.
The PIC is simply programmed in the same way as programming a device mounted in the ZIF socket.
