Hi, you describe a problem that is listed in the Data Sheet and in the Errata Sheet. While I agree that this can be an issue for some applications, the Errata...
IMHO stating "reset is flawed" and "workarounds are available" is nice, but I would also expect upgrades to the chips with corrected known problems. I see...
I did not wanted to be polemical, nor I wanted to start a flame. I should say that I 100% agree with Jan: the purposes of LPCs can be disattended with this...
This problem is not specific to Philips. I'm using a Microchip (not by choice!) rfPIC12C509 that exhibits this same problem. If you reapply power to it while...
Tom, here is what you are missing: If you switch off power, the voltage in your system will go down to a threshold of a diode drop rather rapidly. So the range...

hello, I want to know about UART performance. (1)In case of LPC900 series Microcontrollers use UART, How much will permissible range of error margin? (2)The...
Hello, the permissible Error margin combined over the transmition of a byte including start and stopbit has to be less than half a bit. Half a bit is 50%,...

All, application note 10258 'How to use the LPC900 In-circuit programming (ICP)' shows the configuration of PCL and PDA pins for LPC935 to be at p0.5 and p0.4,...
All, PHILIPS claims in the data sheets for the LPC9XX family that the MCUs can operate at 2.4V to 3.6V. Have you tried to get one of them run at 2.5V? I've...
Hi there, You need to disable 'brownout detection' in DEVICE CONFIGURATION. Then it will work upto 2.4V, else it will hang/reset/stop-working at 2.7V. Hitesh...
Hi friends, I have two types of LPC922. One lot is LPC922F CCxxxx (TSSOP), other in LPC922FN CCxxxx. The verF is supporting multiple programming using ISP,...

I've had trouble getting LPC935-936 devices into programming mode too. What worked for me was to set the reset-output pin from the ICPISPbridge program to...
Gertjan, which of the two you mentioned is what? For LPC935: PDA - p0.4 PCL - p0.5 For LPC936: PDA - ... PCL - ... p0.5? p0.6? Can you point me to an internet...

Hello Gertjan, Thanks for the tip. I will go through bridge code and will try to implement. I tried using 10k pullup on p0.4, p0.5 and p1.4(reset); it improved...

Gertjan, you wrote in your former mail that P05 and P06 were used... for LPC935 it is P04 and P05... I suppose you meant P04 and P05, right? Thanks, Maciej...
