Part Number:AMC1305L25
1. Is AMC1305L25 able to be configured as single-end communication when both CLKIN_N and DOUT_N pin are connected to ground? Or only LVDS communication is used?
2. Is SN65LVDT14 only one transceiver for the AMC1305L25 communication with C2K/MCU?

Dear TI Hello,
I am working on the migration code of the HVACI_sensorless floating point from the F28335 to the F28377D,

Sir I need to burn my program into flash memory and it should remain over there permanently
Now when I'm running a blinking LED program, led blinks until my board is connected to power supply once I remove power and reconnect it the code is lost from the memory
Can you please provide the code for burning program permanently into flash memory using JTAG so that whenever I power it the LED should blink.
TVS is common ESD protection component and I have questions regarding it.
1. Some TVS families seems be designed for power lines particularly. Should we select different TVS for power lines and data lines?
2. Sometimes, I see engineers use TVS for USB VBUS and the maximum VRWM (Reverse standoff voltage) is 5.0V. However, the VBUS may exceed 5V. Many USB power supplies provide the 5.1V or 5.2V voltage and the specification of VBUS is 4.75V to 5.25V. I'm wondering If it is a good idea to use the TVS which maximum VRWM is 5.0V for USB VBUS? Or it is better to select the TVS which is with 5.5V or 6.0V VRWM?

Part Number:LM4898
Hello,
When the LM4898 is put into shutdown mode, can I assume that the output stage is turned off and that the output enters a high-impedance state? In particular, I would like to ensure that there is no signal pass-through from input to output when shutdown is enabled.
Thank you!

Part Number:TMS320F28335
Tool/software: Code Composer Studio
Dears,
F28335 is used for the motor driver, there are 2 parts of the code, one is the bootloader code, the other is the application code.
the bootloader code was programed into DSP first, and then the application code will be programed. If the later application was download in a CAN bus, the later code will not cover the bootloader code, but if the application code was programed in a JTAG way, the later code will cover the bootloader code, how to avoid this covering when using a JTAG way to down load the application code after the bootloader code was download?
Finally, is there a better way to solve this issue? for example, how can I down load the bootloader code and application code in one time rather than separately?
Thanks.

Hi,
Customer received EVM board but PC can't capture USB HW.
So far, PC still can't capture USB HW.
Please help to advised, thank you.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Our verify/check process our below:
1.Install PCM3070-K CS v1.2.3(Rev.A) which include TAS1020B(digital audio interface) driver.
But PC can’t capture new USB HW.
2. Try to swap in PC(Win7 base) other USB port and install PCM3070-K CS in the other 2 PC(WIN8 and Win10 base) also can’t capture USB HW.
3.Right-click the PCM3070EVM-K CS shortcut and select properties to choose Win7 compatibility mode => Still can’t capture USB HW.

Part Number:OPA549
Dear Power OP-AMP team, We want to drive a DC motor using 18 bit/20 bit DACs with an update rate of 2.5us, and the precision DAC signal is used to control the speed/position of a DC motor. We want to use Power OpAmp between the DAC and the motor. The DAC is 18/20 bit, is there any Power OpAmp that is low noise, and is capable of delivering 2A~8A current that we can use? we are currently evaluating Opa549-HiRel in simulation, and would like to know whether it can be used in this application, or, do you have any alternative suggestion?Part Number:BQ27426
Hi,
I'm having troubles enabling Qmax and Ra update.
After POR I update Chemistry Profile and I set Design Capacity, Design Energy, Terminate Voltage and Taper Rate and disable the SLEEP mode. All other parameters are unchanged.
However Qmax and Ra are never updated, what am I doing wrong?
Control_Status(QMAX_UP) = 0
Control_Status(RES_UP) = 0
Control_Status(RUP_DIS) = 1 - why is it disabled and how to enable it?
Control_Status(VOK) = 0 - when is VOK set?
Control_Status bits are the same during charging and discharging...
Thanks!
Part Number:LMR33630
Hello,
I designed a board using the LMR33630ARNXT in the inverting buck mode to generate -9V from a 24V supply and I am seeing issues when power is cycled and the output capacitors are not discharged.
On initial power up with everything discharged the inrush current is a quick spike as expected but when power is cycled and the inrush current peaks to 3.5A for ~25ms causing a supply rated for 3A to enter over current protection.
Swapping to a supply rated for 5A the power rail comes up but the large inrush current is still seen when powering VIN without discharging the Output capacitors.
The EN pin was tied to VIN so the device starts up when the VIN rail reaches ~2V (LMR33630A undervoltage lock-out threshold), could this be the issue?
I am not sure why there is a difference when powering the board with the output caps discharged vs charged.
Thanks,
Sean
Part Number:CC2640R2F
Tool/software: Code Composer Studio
Hello.
I have a custom board using the 4x4mm QFN version of CC2640R2F, which I try to debug through the XDS110 of the CC2640R1 launchpad. The following error message is displayed every time I attempt to flash the ble5_simple_peripheral demo project :
IcePick_C: Error connecting to the target: (Error -242 @ 0x0) A router subpath could not be accessed. The board configuration file is probably incorrect. (Emulation package 8.1.0.00005)
Everything works fine when I attempt to flash the device located onto the launchpad, so it most likely doesn't come from my computer.
Also, when I run a test connection on the .ccxml target config file, it works once after reset, but the subsequent tests will return the same error message, until next reset. This makes me think it is probably not a hardware problem.
I am using the RCOSC configuration and the CC2640R2DK_4XS board file provided by TI (at least I set CC2640R2DK_4XS in the build predefined symbols, if there is something more to do to use the file, please tell me).
Most topic about this same error message speak of a problem occurring from time to time, or were caused by hardware problems, so I could not find any helpful information.
I guess the problem is somewhere in the board configuration firmware, but I don't know what it could be exactly, so my question is where should I look, or what should I try to change from the demo project?
Thank you.
Part Number:LAUNCHXL-CC26X2R1

Hi,
The target here is to print out the scanRsp data of type `GapScan_Evt_AdvRpt_t` in SC_EVT_ADV_REPORT, from a legacy BLE 4.x peripheral.
I have loaded the central example project from latest simple link 3_10_00_53.
Then followed the following steps to print the 1M PHY ScanRsp,
http://dev.ti.com/tirex/content/simplelink_academy_cc13x2sdk_2_20_03_05/modules/ble5stack/ble_scan_adv_basic/ble_scan_adv_basic.html
We are using a custom peripheral, with legacy scanRsp (scanable).
so I changed `SCAN_TYPE_PASSIVE` to `SCAN_TYPE_ACTIVE`, and
#define DEFAULT_SCAN_PHY LL_PHY_NONE
Looking at `evtType` , it seems to hold the value 0x13, which according to LL_ae.h is a bitfield of CONNECTABLE + SCANNABLE + LEGACY
so I added printing the ADV_RPT_EVT_TYPE_LEGACY
static uint8_t roww = 0;
//Print scan response data or advertising data
if(0!=(pAdvRpt->evtType & ADV_RPT_EVT_TYPE_LEGACY))
{
Display_print1(dispHandle, (TBM_ROW_APP + 10 + (roww++)), 0, "ADV_RPT_EVT_TYPE_LEGACY: %s",
Util_convertBdAddr2Str(pAdvRpt->addr));
Display_print1(dispHandle, (TBM_ROW_APP + 10 + (roww++)), 0, "ADV_RPT_EVT_TYPE_LEGACY: %s",
Util_convertBytes2Str(pAdvRpt->pData, pAdvRpt->dataLen));
}
else if(pAdvRpt->evtType == ADV_RPT_EVT_TYPE_SCAN_RSP)
{
Display_print1(dispHandle, (TBM_ROW_APP + 10 + (roww++)), 0, "ScanResponseAddr: %s",
Util_convertBdAddr2Str(pAdvRpt->addr));
Display_print1(dispHandle, (TBM_ROW_APP + 10 + (roww++)), 0, "ScanResponseData: %s",
Util_convertBytes2Str(pAdvRpt->pData, pAdvRpt->dataLen));
}
else
{
Display_print2(dispHandle, (TBM_ROW_APP + 10 + (roww++)), 0, "Advertising Addr: %s RSSI: %d",
Util_convertBdAddr2Str(pAdvRpt->addr), pAdvRpt->rssi);
Display_print1(dispHandle, (TBM_ROW_APP + 10 + (roww++)), 0, "Advertising Data: %s",
Util_convertBytes2Str(pAdvRpt->pData, pAdvRpt->dataLen));
}but it doesn't have the scan response... could you please let me know what is still missing here?

Part Number:DP83822I
Dear Technical Support Team
I'd like to replace from TLK105LRHBR to DP83822IRHBR.
I see DP83822 Hardware Rollover.
http://www.ti.com/lit/an/snla262/snla262.pdf
I refer to this document.
Is it possible to replace about AC and DC characterization, too?
AC and DC characterization seems be slightly different between TLK105LRHBR and DP83822IRHBR.

Part Number:DS90UB925Q-Q1
I posted the following in this forum a while ago about pairing DS90UB921 with DS90UB940 :
https://e2e.ti.com/support/interface/f/138/t/790309
I am not too sure how well the with DS90UB921 is being distributed (discontinued at digikey non stock in Mouser). Long story short, I am wary about using the part in design. Based on the forum post above:
1) Is there anything I have to be worried about by using the with DS90UB925 instead of the with DS90UB921 with the with DS90UB940?
2) On page 26 of the UB940 it says: Note: if paired with a DS90UB925Q-Q1serializer, the devices must be configured into 18-bit mode to allow usage of GPIO pins on the serializer. Does this mean I would not be able to use the GPIOs on the serializer if I'm doing 24-bit?
3) On page 31 of the UB940 it says: The DS90UB940-Q1 is also backward compatible to the DS90UB925Q-Q1, DS90UB925AQ-Q1, and DS90UB927Q-Q1 for PCLK frequencies ranging from 25MHz to 85MHz. Does this mean I can't use the full range of the UB25 (5 to 85MHz) when paired with the UB940? My sensor does 13.5 MHz or 27 MHz only... if this is the case I'll have to use 27 MHz?
4) Why is the distribution of the UB921 so unorthodox?
Thanks,
JP
