Other Parts Discussed in Thread: CC2640
Hello,
a customer has some questions regarding migration from CC2640 to CC2642. He has compared schematics for both devices. Please respond shortly. Going form top left on the schematics snippet below:
- input capacitor C6/C103 for DC/DC converter – capacitance changed from 10uF to 22uF
- DC/DC converter coil L1 - inductance changed from 10uH to 6,8uH
- output capacitor C8/C105 for DC/DC converter – capacitance changed from 10uF to 22uF
- Balun network C31/C31 – capacitance changed from 6,8pF to 12pF
- Crystal Y2 – change from 24MHz to 48MHz, I found on TI wiki three suitable crystals for CC26x2, but is any of them automotive qualified??
- I also found, that on TIDA 01632 capacitor connected to DCOUPL (pin 23, C25) is 100nF, but on devboards (C19) is 1uF, is it feasible to use 100nF cap with CC2642??
- Just to be clear – CC2640 & CC2642 are pin to pin compatible
Thanks, Stefan
