Part Number: TSC2004 Other Parts Discussed in Thread: TSC2003 Hi,
is there an internal pull-up resistor on the reset pin?
Can the reset pin be left floating or is any external circuitry needed?
Best regards
Part Number: TSC2007 Other Parts Discussed in Thread: TSC2003 Hi,
during power ON, some times TSC2007IPWR goes in to lockup state & does not respond

Part Number: TSC2007 Other Parts Discussed in Thread: TSC2004 , TSC2003 Hi support team.
I received a question from my customer about TSC2007.
Could you give us the following information in comparison with TSC2004? ・ Does TSC2007 have a slower response…
Part Number: TSC2007 Other Parts Discussed in Thread: TSC2003 we have 2 questions
1) i see that there was a fix for the POR issue with I2c with Rev C of this part. is there any way to know based on ordering info or labelling on the part to know if what…
Hello Kenji,
For PD0 and PD1, I think you can use the same table shown in the TSC2003. The table is shown below. The difference between "01" and "11" is whether the reference is ON or OFF.
For PENIRQ, the output should be HIGH and it is pulled…
Bruno,
Yes indeed it is the external device that has got stuck. The TM4C is behaving perfectly.
I believe some I2C slave devices have a watchdog timer which resets the internal circuitry in these circumstances.
I am using a TSC2003 touch screen chip…
Hi Dror,
TSC2017 is compatible with TSC2003 and TSC2007, therefore TSC2017 should be Advanced Command-Based. You can find an example code in the next link: Reference Firmware .

Adrian,
We have several Touch Screen Controllers and their selection depends on not just the analog interface, but also how it is controlled. One set uses command-based technology (for example: ADS7843, ADS7845, TSC2003, or TSC2007) and a second sets…
Hello Andy,
I have a working firmware; just some kinks need to be ironed out. I meanwhile replaced the TSC2007 with a TSC2003, and this chip does not exhibit the issue with getting stuck with SCL low. With the TSC2007 I was able to work for only a few…
