Find Wireless ARM MCU

cylee_acc

Hello everyone,

I’m looking for recommendations for a wireless ARM-based MCU for a research prototype.

Target specifications:

  • 32-bit ARM MCU with operating frequency > 78 MHz

  • On-chip ≥ 512 KB Flash and ≥ 64 KB RAM

  • Integrated low-power wireless radio (Sub-GHz preferred)

  • Integrated power amplifier ¶ supporting up to 20 dBm TX output

  • Small package options preferred (QFN or WLCSP)

In addition, I’d like to know whether any suitable devices are available as bare die, known good die (KGD).

If possible, please also share links to datasheets, reference designs, and current availability.

Thanks in advance for your help.

    Thank you for the suggestion.

    I have reviewed the STM32U series; however, I was not able to find any information indicating the availability of a bare die or known good die (KGD) option.

    Could you please confirm whether a bare die or KGD version is available for any devices in the STM32U family?

    Thank you for your assistance.

    If you need information of that sort you will need to establish dialogue with the manufacturer or possibly their local agent.

    Bare die only make sense in special circumstances (usually only in very large numbers) and are rarely stocked by distribution.

    What is your project, and why do you want to use an un-packaged device ?
