nRF24LU1+, how fast of AES co-processor?

[kennychien]

Hi ,

I found nRF24LU1+ build in AES co-processor, but I cannot found the processing speed (the time for finish one AES processing) on datasheet.

Because my customer would like to add AES security on wireless keyboard & mouse combo set and I am study the possibility if I can keep dongle design by using nRF24LU1+ .

Thanks & Regards,

Kenny

The actual decryption/encryption takes about 45 clock cycles.

Hi Kenneth,

There is no clock tree information on datasheet, how about one clock speed to AES co-processor block if nRF24LU1+ run with external crystal 16Mhz?

That is right. So the AES is very quick, about 3us.
