What is the difference between the two memories? apart from size? something else has to change the size, so that one reads it and the other does not.
TLF35584 on TC366TH v1.0 eval board can successfully enter normal mode. However when I try to switch to STANDBY mode or SLEEP mode it doesn't enter these modes. When I try to switch from normal mode to standby it enters to INIT state. Similarly, when I try to switch from normal to sleep it enters to WAKE state. I checked and confirmed that ENA , WAK and SPI commands. Also, I tried to switch from WAKE state to Standby state but it switched itself to INIT mode. I also can switch from INIT to Normal mode again. There is only two conditions that make impossible to switch to standby or sleep mode which is this condition: "MCU current from QUC did not fall below configured threshold" and "MCU current from QUC did not fall below threshold if configured".
How can I configure MCU current from QUC threshold? or is this the only problem for switching between modes?
I need help. Look to state diagram in datasheet.
Show LessHi, I have some questions from the customer regarding the S29GL256S10TFV010 and S25FL256SDSMFV010 devices. I would appreciate it if you could help answer or point me towards the correct resources for the following for the two devices:
Thanks in advance,

Show LessHello all,
Most of the data I'm trying to transmit seems to be going between the FX3 and the other chip just fine, but I'm periodically getting zero length packets seemingly coming from nowhere. I've been trying to debug this, but everything I've tried has been a dead end so far.
I'm trying to use the FX3 to connect an 8051 on our board with a host application on a windows PC. My setup is as follows:
Now the problem I'm seeing is that, the 8051 sends a keepalive signal periodically to the host app, and every once in a while, we get a zero length packet as well.
Here's what I've tried in my investigation:
I suspected that maybe there's noise or something changing the PKTEND pin long enough to trick the state machine into sending a ZLP, but my coworker has already dismissed that notion. He's the hardware guy, so I can't really make him check it, and he didn't leave a way to attach a scope or anything to the pin, so wouldn't be easy.
If anyone has any suggestions of what might be going wrong, or ideas for other things I could test, I'd love to hear them.
Show LessDear community,
On https://community.infineon.com/t5/MOTIX-MCU/BLDC-Sensorless-FOC-TLE9879-Arduino-Kit-24VDC-and-high-speed/td-p/340304 we solved how to run the TLE9879 with 24VDC main voltage. Because the TLE9879 Arduino Kit is not possible to configure if we don't have the Segger J-Link for programming it, I confirmed the solution with the TLE9879 EvalKit V1.4 configurable by USB.
I open a new discussion about this time the PI Controller and the BEMF and FOC projects that I try to adapt for my application of driller:
Motor used: 16mm diameter 1 pole pair 24VDC sensorless BLDC motor with 30.000rpm maximum speed, 90µH and 1,3ohm phase to phase, 1750rpm/V.
Objective: to apply a varying load on the axis without stopping the motor and with a speed remaining constant. When a blocking current is reached (maximum torque), the motor is blocked then.
The BEMF software has not so much documentation but after several tunings in the Config Wizard I can obtain good performances and drive the motor from 2.000rpm to 30.000rpm. On middle/high speeds the blocking current is around 5A and on lowest speeds, around 2A.
The improved settings are: "2" polepair, "400" Ki, "100" Kp, "0.01" Speed Filter Time, 15 KHz PWM.
I got also good performances with: "2" polepair, "0" Ki, "400" Kp, "0.01" Speed Filter Time, 10 KHz PWM.
Now I would like to increase the current on the low speeds without affecting the high speeds performances. But when I change the PI Controller parameters for low speeds, the high speeds performances are degraded. Is there existing a documentation for the TLE9879 PI Controller with the formulas used by the BEMF software and its PI Controller? Perhaps someone can propose me good PI values to test for the motor parameters I use?
If found this interesting application note https://www.infineon.com/dgdl/TLE7242G-TLE8242-2L%20-Application-Note_KP_KI_V2_0.pdf?fileId=db3a30431ed1d7b2011eee8f965a5485 but it is for another software driver I guess, and after calculation of the KP KI values it didn't improved my application. Also the formulas from a comment in my previous post didn't help.
The FOC software is more complexe to configure but more documented. Is this FOC method compatible with my motor and application? Because after several trials, I cannot run my motor as good as on the BEMF method.
Many thanks in advance for support.
Best Regards,
Julien
Show LessI have a technical question about the External Crystal Oscillator (ECO) used in this microcontroller, the frequency of this crystal should be between 3.988- to 33.34-MHz. [ the microcontroller is " CYT2B94CACR0AZSGST"]
I'm asking about the suggested PPM of this crystal.
I wonder choose a crystal to implement with this microcontroller and I have many choices of crystal, I need to fix one of them and I did not have the information of the recommended PPM of the External Oscillator in the datasheet.
Hello community!
I am using a Psoc 63 CYBLE-416045 processor and I wanted to know if it is possible for the BLE to trigger an interruption when a specific advertisement is detected.
I have a system that has its processor in sleep mode to save battery and would like to have the BLE scanning/waiting for a certain advertisement, if that happens the system will wake up. Is it possible to configure the BLE to do this with the processor in sleep mode? can the BLE be configured to work in such way? Is there any code example i could refer to?
Thank you in advance for any information related to this.
Dear supporter
I want to translate the following KBA(KBA235128), please confirm to my work.

Show LessHi , I am currently working on a project where I need to control a bldc motor sensorless and I found that infineon offers many types of evaluation board (TLE9879) that can helps me with this project but i didn't know what is the best evaluation board for me and what are the main differences between them ? I have read the datasheet but I still don't see big differences for exemple between the eval kit and the 100 w auxilary water pump and the 1kw engine cooling fan ? and also I have noticed that the TLE9879 EVALKIT offers complete evaluation of all functions and peripherals of the TLE9879QXA40 and allows direct connection to a BLDC motor so why is there a big difference in the price between this one and REF_WATERPUMP100W for exemple ?
Thank you very much for your help
Show LessHi
I have a question about the exemple codes that exist in Keil Software specifically "driving BLDC MOTOR in sensorless mode " code , so my question is : Can we use this exemple code with all evaluation boards TLE987X for exemple EVALB_VQFN or only for TLE9879 EVALKIT as it is shown in the video in infineon website ?
I mean in this code , is there some parameteres configured that works only with TLE987X Eval kit or it is standard code for driving BLDC motor in sensorless mode no matter the TLE987X Eval board used ?
Thank you .
Best regards.
