Frequently Asked Questions (FAQ)

Q: Can the CC1110F32RHHR directly replace the CC1180RSPR on existing PCBs?

A: Yes. Both devices use the identical 36-VFQFN Exposed Pad package format with matching pin assignments for power, ground, and signal interfaces. No PCB modifications are required.

Q: Are there differences in frequency band coverage?

A: The CC1110F32RHHR operates across 300MHz ~ 348MHz, 391MHz ~ 464MHz, and 782MHz ~ 928MHz, which encompasses all CC1180RSPR operating frequencies (315MHz, 433MHz, 868MHz, 915MHz). Full frequency coverage is maintained.

Q: What is the impact of the higher data rate specification on the CC1110F32RHHR?

A: The CC1110F32RHHR supports 500kBaud maximum data rate compared to the CC1180RSPR's 200kbps. This represents enhanced capability that maintains backward compatibility with existing firmware and protocols operating at lower data rates.

Q: Are there supply voltage or power consumption differences?

A: Supply voltage ranges are identical (2V ~ 3.6V). Receive current for the CC1110F32RHHR ranges from 16.2mA to 21.5mA, compared to the CC1180RSPR's 16.2mA specification. This variation falls within acceptable operating margins for most applications.
