What is the difference between MB90F549GPFV-GSE1 and MB90F549GPF-GE1? The first part number have 2 extra letters " V"and "S", what is the meaning of the extra 2 letters? And do you marking informatio/examples for them?
Show LessHello,
We are currently using an FMx family of microcontrollers, and we are using files provided by Infineon (including the former Cypress).
These include the source code and header files (xxx.c, xxx.h, xxx.inc) of the "microcontroller I/O register declaration file" and "I/O register macro declaration file".
Am I correct in understanding that these do not fall under FOSS (Free Open Source Software)?

Hello all,
for a couple of months now we are experiencing sporadic PLL synchronization losses during our temperature test campaigns. Before that, the same product seemed to work fine during the tests. We don't have any hint about a change in the hardware or in the test test setup which could cause the sudden problems.
One assumption is that there could be an EMI problem. But there is no explanation why we had no problems before.
Does anyone know about the PLL being so sensitive under certain conditions?
The PLL setup seems sound and in spec. But is it possible that certain settings are more robust than others?
Would be glad to get new ideas, since we are running out of them now.

Show LessHello,
FM4(S6E2H16G0AGV20000)のクロックギアを使用して、
低周波から高周波へ徐々にシフトさせて、電源電流の変動を抑えたいと考えております。
以下のPeripheral Manualは確認しております。
https://www.infineon.com/dgdl/Infineon-32-BIT_MICROCONTROLLER_FM4_PERIPHERAL_MANUAL-UserManual-v06_00-JA.pdf?fileId=8ac78c8c7d0d8da4017d0f9117267e56
クロックギアを使用して低周波から高周波に切り替える際に、かかる時間の計算方法を教えてください。
(メインPLLクロックの64クロック×ループ数×ステップ数であってますか)
また、もしクロックギアを使わずに、急激に周波数を変化させた場合、変動する電源電流の大きさはどのくらいでしょうか。
(周波数の変化幅と、電流の変化量に相関関係があるのでしょうか)
I would like to use the clock gear of FM4 (S6E2H16G0AGV20000) to gradually shift from low frequency to high frequency to suppress fluctuations in power supply current.
The following Peripheral Manual has been confirmed.
https://www.infineon.com/dgdl/Infineon-FM4_Family_Peripheral_Manual_Main_Part_(TRM)-UserManual-v06_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0f911bce7e60
How do you calculate the time it takes to switch from low to high frequency using clock gear?
(Is it 64 clocks of the main PLL clock x number of loops x number of steps?)
Also, if you suddenly change the frequency without using a clock gear, how much will the power supply current fluctuate?
(Is there a correlation between the width of the frequency change and the amount of current change?)

Show LessI want to debug the mcu TC1782 by setting the breakpoints in code and simultaneously it should also flash the firmware so that we are able to see that during the firmware flashing process which section of code it is in.
I tried using the debugger but when I connect the debugger I can only debug the code and can not flash the firmware.
I there any method by which we can perform the same?
Hi ,
We are using BSC117N08NS5 FET & SLB9670XQ2.0 IC in one of our designs where we need the below thermal data. So kindly share the thermal input ASAP.

Dear sir
Please tell me how i can communicate the xc866 microcontroller with memtool
Hello! We are pursuing the replacement of an XE167F96F80LACFXUMA1C with an XC228796F80LACKXUMA1 as per previous PCN guidelines. Would I assume immediately that the appropriate compiler for the latter must be used to compile present code with the latter part number IC as the target? Is there any information downloadable about compatibility?
