Hi team, working with a customer on this. In a recent PCN, the TL16C754BPN is being replaced with TL16CP754CPMR. Please provide a list of differences or a migration guide for this.
Hi Mario,
I also received ooo message. I'll put what I responded with here.
"In reference to Kannan sending me the PCN."
Thank you for bringing this up. I checked our PCN repository and I didn’t find this PCN so it must not have been registered in the system quite yet which is surprising.
It looks like the PCN is referring a replacement of the TL16C754BPN device and suggests the TL16CP754CPMR. We don’t have a migration guide other than the recommended replacements listed in the PCN.
As for differences between the two devices, one of the major differences is that they are not p2p compatible. The “C” version is offered in PN and FN package types one with 80 pins and the other with 68. “CP” version is offered in a 64 pin package. Another factor is that the “CP” device is newer and made with improve process technology resulting in a smaller die size and I believe better overall cost structure. It supports RS-485 mode support, and has a couple more additional features over the older TL16C754B device.
"Kannan asked for a more detailed list of differences i.e. migration guide."
Below are the differences that I found when comparing the datasheets side by side:
Main difference lies in the pin counts, which would change the package, and the feature list. “CP” version adds two additional modes RS-485 and a more complicated infrared protocol mode found on page 41 of the datasheet. Supply voltage differences, as well as crystal oscillator and clock support.
Overall, they are very similar from a software perspective. The internal registers maps are nearly the same, and the way the baud rate is configured is the same.
Regards,
Tyler
