hello,
May I know if TI has not touchscreen controller that come with hardware filtering like , Microchip part, p/n: AR1020?
for Example refering TSC2014 Is the pre-processing stage consider of filtering.
I am looking for a 4-wire resistive touch controller with I2C interface and hardware filtering.
Do you have any to recommend?
Thanks,
Joy
Joy,
Many of TI's TSC devices have the build-in filtering capability. For example, TSC2004, TSC2017 or TSC2014 meet your requirements of 4-wire resistive TSC with I2C interface and hardware build-in filtering.
Please feel free to ask if you need more info!
Regards,Wendy F.
Dear Wendy,
May I know it seem like datasheet for TSC2014 available on the web is incomplete. Can you pls confirm?
Secondly, the hardware filtering for TSC2004, TSC2017 is at the pre-processing block?
Hello Joy,
You are right -- the TSC2014 d/s on TI web is not the full version! May you please provide me your email address and the customer info so that I can email to you directly?
Yes, the hardware filtering in TSC2004/TSC2017 is implemented at the pre-processing block.
Best regards,Wendy F.
Pls send me the datasheet at joy.tan@serialsystem.com.
The customer info i will provide you offline.
thanks,
Just emailed you the d/s full version. Please feel free to ask if there is further question!
Pls send me the full version datasheet & reference circuit at eric_lo@yosungroup.com.

Dear Eric,
Please email me the customer's info to w-fang1@ti.com so that I can provide you the TSC2014 full d/s. About the refrence circuit -- you may find the TSC2014EVM and EVM-PDK user's guide at TI website (http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=sbau182&fileType=pdf), where you can find the EVM schematic and layout.
