Legacy microcontrollers Forum Discussions
Hiii all!!!
I want to know that is there any dedicated IC for measuring three phase current and voltage also kWh.
If it is kindly let me know the part number of it.

Dears.
Now my customer is using MB96F6B5A/R to implement HVAC.
By default, vector table is located in the address from 0xFFFC00 to 0xFFFFFF.
We are wondering that is possible to change vector table address because we want to put digital signature value in the area of 0xFFFC00 ~ 0xFFFFFF.
If yes, could you tell us how to relocate vector table address ?
Thanks and best regards,
Kevin Han.
Show LessHello Sir/Madam
I am looking for a microcontroller and gate driver circuit along with mosfet Or igbt for a Hybrid ev vehicle motor of rating 48V 500W .
Show LessHello.
I implemented from [1] the chapter 8.14.3.1 "ECC Software Testing Support". I implemented the chapter for the DSRAM, DPRAM, and PSRAM.
[1] chapter 8.14.3.1 also states "If ECC operation is enabled (ECCCON.xEN = 1) the corrected data value (2000H) is read and an ECC error is indicated.".
Above second underlined is working for DSRAM, DPRAM, and PSRAM. That’s fine. And no question.
Above first underlined is working for DSRAM and DPRAM. That’s fine. And no question.
Above first underlined is not working for PSRAM. This is my problem.
I allow to describe my problem a little bit more detailed, with parts of my implementation. For the relevant code parts of my implementation see [2].
At [2] line 31 "POINT 1" is observed:
- errorcode has the value FCT_NO_ERROR.
- biosRamEccParityTestRegECCSTAT has the value 2.
At [2] line 38 "POINT 2" is observed:
- errorcode has the value FCT_NO_ERROR.
- biosRamEccParityTestRegECCSTAT has the value 1.
At [2] line 45 "POINT 3" is observed:
- errorcode has the value FCT_ERROR_ARGUMENT; reason: [2] line 80 "POINT 4" is executed. Note:
- For [2] line 82 stated "xxxLocation6" were following different values observed: 0, 0xC0FA, or 4.
- biosRamEccParityTestRegECCSTAT has the value 4.
So my above stated problem boils down to my following question: Why is for the PSRAM, at [2] line 64 "POINT 5", [1] chapter 8.14.3.1 stated "If ECC operation is enabled (ECCCON.xEN = 1) the corrected data value (2000H) is read" not fulfilled?

I just started using SK-FM4-216-ETHERNET Evaluation Board and it comes with a few examples but I'm looking for the most basic, to understand the use of inputs and outputs, press a button and turn an LED things like that.
Is there any sample code that explain the use of GPIO's?
The software I'm using is Keil uVision 5

im looking to hire someone who will be able to read/write specific automotive engine ecu which mounts password protected infineon tricore tc17xx microcontroller
currently no tool on the market offer support for this ecu type,
i am aware its complex job but i am interested to solve, price is not an issue if it can be solved, i have alot of these units waiting,
best regards
Show LessHello.
[1] chapter 8.14.3.1 states "The ECC error detection can be triggered on purpose to test the detection itself and the associated trap routine. This test option is available for RAMs". So, previous stated chapter describes how the RAM ECC error detection can be tested. That’s fine.
My question: How can the flash ECC error detection be tested?
Question reason: In [1] chapter 3.10.7.1 I see the flash ECC description. But I don’t find in [1] a chapter for the flash, which is similar to (above stated) [1] chapter 8.14.3.1.
Regards
Oliver.

Hello,
I apologize in advance if this question is in the wrong category.
I had a question regarding the die that is inside my Cypress part.
I am wondering if the die is authentic to this component given the following information:
Part number: CY7B185-12PC
Date code: 9513
Lot code: 002450
The markings on the die read: ASPEN, © 1990, 6A185B.
At SMT we are committed to keeping counterfeit components out of mission-critical systems. Any information you can provide is greatly appreciated and helps support our mission.
Thank you!
We purchased the SAK-TC1782F-320F180HR BA from the agency and found that there are two fonts of silk screen and two LOT numbers in the same tape, and many other models with two or more LOT numbers also have this phenomenon, may I ask why? Is this normal? Looking forward to your reply, thank you!
