S2LP Question about Versions

Macias

Hello, can you help me recognize the S2LP version. I read the register DEVICE_INFO1 and I get 0x91 on the RC-S2LP-433 and in the Steval-fki433v2 is 0xC1. I have some problems with RC-S2LP and I think there is a different version of ic. Thx.

I think you meant DEVICE_INFO0.

Both of them are S2-LP, with DEVICE_INFO1 equal to 0x03.

If you purchase S2LP chips now, DEVICE_INFO0 will be 0xC1, as described in datasheet.

The value 0x91 belongs to an older cut of S2LP.

Yes, that was DEVICE_INFO0. I found this: http://www.farnell.com/datasheets/2605120.pdf now I waiting for a new cut of S2LP. Thank for an Answer.

Hello,

I bought some X-NUCLEO-S2868A1 and A2 from RS, farnell and Digikey and it's still cut2.1 (version 0x91), how to buy the last one ?
