TPS65994AD: TPS65994AD customization tool and EEPROM firmware

Hsieh Yulin
Prodigy 45 points
Part Number: TPS65994AD
Other Parts Discussed in Thread: TS3DS10224, TPS65994, TPS65994BF, TPS66994, TPS65994BH

Tool/software:

Sir,

May i know how to get customization tool for TPS65994AD? 

I found a link on E2E forum and apply it but it's pending(refer to below photo) and I didn't get email from system. Could you help us to check the problem?

BTW, could we program the extrnal EEPROM via I2C interface with customization tool or we need to pre-programmed EEPROM?

I only found "TPS65987DDH and TPS65988DH Host Interface Technical Reference Manual" does it could be used on TPS65994AD? 

Thanks a lot

B.R

    I will ping the team about getting you access.

    You can program via the customization tool! This is done via a TM4C123GXL. Or if you have a TPS65994EVM, you can use the on-board TM4C and connected the I2C3 to your board. Once you are happy with the configuration, you can move to pre-programmed EEPROM for manufacturing.

    It is not 100% accurate but 60% of registers do align. It may help a bit but is by no means the correct reference manual. 

    Thanks,

    Hi Yulin,

    Are you using a intel reference design for your TPS65994AD application?

    Hi Jon,

    We refer to Intel Reference validation platform (RVP) PD AIC to select TPS65994AD and use TS3DS10224 to swap AUX_P and AUX_N.

    The schematic doesn't 100% follow up RVP.

    Hi Chris,

    My request for access to TPS65994 design has been approved today and I got the document "TPS6599xAD_TRM" and the application customization tool.

    On application customization tool there does not include "TPS65995AD" at new project device list.

    I check the datasheet the TPS65994BF is pin compatible with TPS65995AD, may I know any difference between these two parts?

    Thanks a lot

    TPS6599x are ROM-based parts. There is a way to 'patch' the ROMs but it is space-limited. Whenever we run out of space on a part, we 'spin' it. So the spins get the TPS6599xYY portion. Each spin in order of release is AC, AD, AE, BF, BG, BH, BI. 

    TPS65994AD is very old and cannot support the current USB-PD spec. It has been recommended for customers who are currently developing Intel REference Designs to use the TPS66994 device as this is all Flash-based and will be supported for many years. The ROM parts do drop out of support because the USB-PD spec changes every 6months and we have to be compliant to that. 6 month changes + limited ROM patch space causes many spins and eventual EoL

    Hi 

    Our board already Gerber out and make PCB now.

    We didn't get this information when schematic review on E2E and I didn't find datasheet for TPS66994 on TI website.

    Does the TPS66994 pin compatible with TPS65994AD?

    Does it mass production? Could you provide datasheet for me?

    Thanks a lot

    TPS66994 is not pin compatible with TPS65994AD but is compatible with the CFP package so if you are using a competitor part as well, we will b pin compatible with that. 

    You can move forward with the TPS65994BH would be best.

    Hi,

    Did you have comparison table between TPS65994ADRSLR and TPS65994BHRSLR?

    Refer to datasheet TPS65994ADRSLR is pin compatible with TPS65994BHRSLR, we already purchased TPS65994AD 170pcs

    We do not have a table comparison between the two. However if you have access the the TPS65994AD datasheet and TRM, you also have access to the TPS65994BH datasheet and TRM. 

    Thanks,

    Chris
