Part Number: TPS23880EVM-008 Tool/software: Code Composer Studio Hi,
I would like to ask is it necessary to do impedance matching on differential Pairs?
Does it make a defference on data transmission without doing impedance matching?

Part Number: TPS23880EVM-008 Other Parts Discussed in Thread: TPS23880 , MSP430FR5969 Tool/software: Code Composer Studio Hi,
There was one question about TPS23880 EVM,
the EVM can work well when using GUI solfware,but when it working with MSP430FR5969…
During this time communication is lost. During this condition all I2c read return 0x80.
At a time I connect either GUI/ micro controller through J2 controller.
I verified the i2c communication through oscilloscope.It always return 0x80.

Hi Mao,
Thanks for confirming! We have a newer SRAM Patch for TPS23880 v2 that can be found in the TPS23880 product page under 'more information'
As for the code, it is interesting that you can write/read on other addresses. This is something…
Hi Darwin,
I have now tested the WAP with the demo board TPS23880EVM-008 and the same error occurs. After some research I found out that there was a problem with the detection resistor. It was too low. So I added additional 2k resistors to the correspoding…
Thank you for unlocking the thread.
We are able to reproduce the problem described using evaluation module BOOST-PSEMTHR-007 with daughterboard TPS23880EVM-008. The EVM is connected via USB Interface Adapter (J2) to I2C bus of our device, the daughterboard…
Hi Alex,
Please refer to TPS23880 MSP430 reference code and check the TPS23880EVM-008 EVM user's guide about how to initialize the device. If there's no MCU, the device is in off mode and will not be operational. Please check out TPS23881 device…
Hi Brendan,
The USB2ANY Explorer uses a different USB2ANY firmware version than the TPS23880EVM GUI. Can you try the following:
Disconnect USB2ANY from you PC and close USB2ANY explorer and TPS23881EVM GUI
Make sure the jumpers on TPS23880EVM-008 daughter…
