Procurement Notes
When requesting a quote for CC3220R, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For MCU, processor and logic IC sourcing, package, operating voltage, temperature grade, speed or frequency grade, firmware or mask version, lifecycle status and programming requirements should be checked before approval.
FAQ
What CPU core does the CC3220R use?
The CC3220R application MCU subsystem uses an Arm Cortex-M4 core operating at 80 MHz, according to the extracted datasheet facts.
Does the CC3220R include integrated flash memory?
No. The extracted facts state that on-chip flash is not integrated for the CC3220R variant. The same note distinguishes it from the CC3220SF variant, which has 1 MB flash.
What Wi-Fi modes are listed for the CC3220R?
The CC3220R supports 802.11b/g/n station mode, 802.11b/g access-point mode for up to 4 stations, and Wi-Fi Direct operation as client and group owner.
