To Infineon employee, The issue about QSPI iLLD for AURIX TC2x7 series
Hello,
I have used the demo code for TC237 app-kit which is provided from Myicp because of working TFT lcd on TC237 app-kit.
I extracted TFT function codes from the demo files because of my project.
The code successfully has been compiled and downloaded on my app-kit with the Aurix development studio v1.2.2
But my app-kit was not work.
My TFT had displayed continuous thin vertical black lines.
So, I tried to exchange QSPI iLLD from v1.0.1.11.0 (version 2019) to v1.0.1.4.0 (version 2017) because I thought the QSPI operating codes had problems.
(The iLLD files were included SpiMaster, SpiSlave and Std folders.)
Finally, My TFT is working well.
I think the latest version of QSPI iLLD is different from old version which was used demo files.
but I don't know what has changed.
Could you tell me the cause of this problem?
And I guess Qspi_0 operating codes which has been included in demo files have to been modified in accordance with latest iLLD version.
(The TFT is working with QSPI_0 function.)
Can you give me the modified QSPI_0 operating code?

ICE5QR0680AZ does not start!
Hello support,
I tried to replicate the "DEMO_5QR0680AZ_42W1" board with some minor modifications. Attached I send the schematic.
The difference is the feedback loop, where the 5V output is only controlled.
I did a production of 300 boards, and half of the boards, the chip ICE5QR0680AZ is in a state that tries to start, and after a while, sometimes it starts and sometimes it doesn't!
Am I doing something wrong? Do I have a feedback loop, calculated wrong?
Best regards
Ivo Bernardo

TC212 Low-power modes
Hi everybody,
I have a question regarding the low-power modes of the TC212S device.
More specifically, I've read from the datasheet (Electrical Specification paragraph) that:
- SUM of all currents = 150 uA (max, Tj=25°C) in STANDBY MODE
- SUM of all currents= 10 mA (max, Tj=55°C, fSPB=1MHz) in SLEEP MODE.
Is there any way to further reduce the current in SLEEP Mode?
Has anyone directly experienced this topic? Is there any advice/tip on how to eventualy approach this?
Thank you.
Kind regards,
Eleonora

GTM dead time module
Hi,
i am working on TC37 trcore uC..
i saw that infineon sample code doesnt have any sample code regarding DeadTime Implementation in GTM, could anyone please help me to sort out regarding the implementation of DTM in TC3x series?
could anyone share the sample code where the sample implemetation of DeadTime Module in GTM? if possible..

Switching frequency for device in PFC
Hello Melli,
You have the right choice for high switching frequency operation.
IKW40N65WR5 is exactly optimized device for PFC application that doesn't require high performance of co-pak diode.
Based on our internal examination it allows the switching frequency up to 75kHz and performs similar or better than equivalent SJ MOSFET (80mohm CoolMOS P7).
The data below can help you.

IR2181 Data Sheet Parameters
If i refer the data sheet of IR2181 and attached an image of the ratings and characteristics. I see huge current values of 100A etc. These are very high values, how to understand them, will the IC will be able
to handle so much current without burning etc? I am beginner in electronics and trying to understand things.

DMA circular buffer: multiple moves per transaction
I've recently started using the DMA more, and I seem to have trouble with setting up multiple moves with automatic source/destination address increase. I've managed to sort out Linked Lists, interrupts from multiple sources, daisy chaining channels.
The issue is that I have setup multiple channels to do two moves: read from a local array and write the value directly to the GTM SR0/SR1 of a TOM channel.
I can get the first move to work, but for some reason, the second move doesn't do anything. I'm not sure what's wrong in my configuration.
Here's my code example:
I'm moving 16bits. The source data is in an array of uint16, so I increment the source address by 1 width. The destination addresses are 0x-------4 and 0x-------8, so I increment by 2 widths. The thing I'm not sure is the circular buffer size, but I've tried multiple configurations and none of them work with the second transfer.
Can you see anything wrong? I suppose its the circular buffer size but I don't think I understand how it works.
For example on the source address, with IfxDma_ChannelIncrementCircular_2, it should be a buffer of 2 bytes. First move will read from (for example) 0x60000000, second move from 0x60000002, then next transfer, it'll select 0x60000000 again due to the circular buffer size.
Same for the destination address, IfxDma_ChannelIncrementCircular_4 is a 4 bytes buffer, so first write to 0xF0000000 and second write to 0xF0000004 then back to 0xF0000000 on the next transfer, right?
Apparently not...

cfg.requestMode = IfxDma_ChannelRequestMode_completeTransactionPerRequest;
cfg.moveSize = IfxDma_ChannelMoveSize_16bit;
cfg.shadowControl = IfxDma_ChannelShadow_none;
/* Source and destination addresses */
cfg.sourceCircularBufferEnabled = TRUE;
cfg.sourceAddressIncrementStep = IfxDma_ChannelIncrementStep_1; //1 width
cfg.sourceAddressCircularRange = IfxDma_ChannelIncrementCircular_2; //2bytes buff
cfg.destinationCircularBufferEnabled = TRUE;
cfg.destinationAddressIncrementStep = IfxDma_ChannelIncrementStep_2; //2 widths
cfg.destinationAddressCircularRange = IfxDma_ChannelIncrementCircular_4; //4 bytes buffer

IR2214 component calculations assistance
Gate resistor calculations are explained in pages 17 to 19 of IR2214 datasheet.
The power dissipation calculations are available at https://www.infineon.com/dgdl/Infine...523ee694b74f18
For Rgon of 5R and Rgoff of 12R and internal Ron of 15R from gate driver, the drive current is Vdd / Rtotal = 15 / 20 = 0.75 A for turn on and 0.55 A for turn off. This is not exceeding the IC capability.
Pdon = 0.5 * Qg * Vcc*fsw *Ron/(Ron+Rgon)
Pdoff = 0.5 * Qg * Vcc*fsw*Roff/(Roff+Rgoff)
Pdstatic = Vcc*Istatic
Pdtotal < Pd of 1.5W as per device datasheet. As per above you are well below this.
Soft shutdown on resistance is specified on page 4 as 90R based on the desat timing requirement.
2W is sufficient to run the three half bridges. Total energy to drive per IGBTs = 0.5 Cgs * VDD*VDD ~ 3 uJ, power required = 3 uJ * 10 kHz = 30 mW x 6 = 180 mW ~ 12 mA.
