Problem with PIC17C44

[Dataman (Neil Parker)]

Hello,

In order to move forward in this matter our engineers will require samples of this device for further testing in our lab. Can you provide this?

Hi, me again, i receive the new programmer but i have news problems... i have the original from Microchip (programmer).

Hello radeonrelive,

Can you confirm that you have implimented the bypass capacitor mentioned in the "Device info" section of the software:

General Info:
In case of unreliable work of this device using universal adapter/module, please connect bypass capacitor (ceramic multilayer, that meet the EIA X7R or Z5U specification value 22nF-100nF) between GND(VSS) and VCC(VDD) pins of this device.
We provide a programming adapter DIL40/DIL40 ZIF AddCap (70-0802) with special soldering pads for better placing of some capacitors. The programming adapter package (70-0802) also contains 5 pieces of 100nF and 5 pieces of 100pF ceramic capacitors.

Hello radeonrelive,

Our engineers have said that frankly speaking we don't understand this situation. Here in our lab the programming works (several chips tested), next solo verify also OK. It looks like the problem is related to the PIC17C44 chips themselves. Can you provide one for testing here in our lab?

BTW, Save buffer to file from the View/Edit window saves only the main memory, but not the config. Do you have a reason not to use the File/Save procedure.
