CC1310: CC1310 issues.

Hank Zhang
Expert 2040 points
Part Number: CC1310

1.IO can be easily reused.I would like to ask if I see SSI is the same as spi.

2.External regulator mode, I am the power supply system of 1.8v, and VDDR_RF is also connected with VDDS to 1.8v, which will not affect my RF performance at 1.8V voltage.

3. The bandwidth of RF matching (868MHZ)

4. Is there any reference design for the voltage part of the 1.8v system for CC1310?

    1) Yes and no. If you check the SPI section in the TRM, the SSI interface can be used for SPI but also as other type of interfaces.

    2) The max TX power will be slightly higher than 12.5 dBm due to slightly higher voltage. Other than that you should not see any difference in RF performance.

    3) The match has been developed to cover 770 MHz to 930 MHz.

    4) www.ti.com/.../swra498.pdf is the only reference design I know of that uses external regulator mode.
