nrf52833

[Tai]

Hi everybody,

We are going to develop on nrf52833 our new product. I have some questions regarding this new module:

1- Is the module available to buy online?

2- I saw the price which is not really different from nrf52840. What is the interest to usenrf52833 instead of nrf52833?

3- Is there any 3.3v pinout like nrf52840 to power other modules?

Thanks

What i know is:

1. You can buy some devboards with the 52833 which look just like the 52840

2. pros of nrf52833 it's cheaper, is temperature resistent and supports the new BT 5.1, but you don't get the same memory and flash and you seem to miss out on the CryptoCell. You however end up paying less.

3: I think it has the same IO as the 52840

Thanks for your reply.

But I need the chip. I checked Digikey and Mouser and I saw that the chip is not yet available.

Hi,

I see there are will be three package variants available:

• QIAA which is described in the documentation, but also:
• QDAA, and
• CJAA (WLCSP?)

Could you give us more insight please?

Sorry, im not experinced with actually buying the chips isolated,but rather the devlopmentkits, since that's what im using at the moment(although the nrf52840).

but of what i could find:

https://www.mouser.com/Semiconductors/Wireless-RF-Integrated-Circuits/RF-System-on-a-Chip-SoC/_/N-af71n?Keyword=nrf52833&FS=True

i don't know the R and R 7 differences but as you said they aren't available yet. I would jus write the store and ask them for support.

The devkits on the otherhand are in stock and ready to be shipped

Okay, I seem found the answer in the product brief. Perhaps it will be as follows:

• QIAA - 7x7 mm aQFN73 with 42 GPIOs
• QDAA - 5x5 mm QFN40 with 18 GPIOs
• CJAA - 3.2x3.2 mm WLCSP with 42 GPIOs
