#138550 - LPC93x Responding to: ???'s previous message |
I myself haven't tried ICP on 28pin parts because... I use simpler ISP based on the MCB900 cct, BUT I see no reason why it shouldn't work.
Do you have CRO to check the waveforms going to the target micro being programmed Vdd, /RST, PCK and PDA etc. Theoretically a little more current will be require for 20 and 28pin parts but the load switch (pnp-npn) should handle that (no sweat!). Try other 28pin LPC93x devices and see if they work. The Flashmagic LPC900 forum might be a better place to post your ICP question as it may be Flashmagic PC s/w related. Here http://forum.flashmagictool.com/index.php...?board=4.0 Please ensure you give an accurate detail description of the operation (from the beginning) and upload in your post the schematics in jpg , pdf or popular file format.
