Energy consumption: Receive data on BLE with MCU/MPU in standby, best MCU/MPU choice?

[BClen.1]

Hi,

 

I want to choose a ST MCU/MPU and I would like the CPU to have BLE, to be able to run a low power mode (STANDBY), use < 5µA in STANDBY and be able to listen on BLE during STANDBY mode

Best is that BLE chip would be in STANDBY as well but listening

So MCU/MPU + BLE in STANDBY would use less than 50µA

Is there a ST MCU/MPU solution?

 

Thanks,

Look at L4 series with Cortex M4. It's low power consumption MCU 's.

Thanks Kamil

But these chips does not include BLE, do they?

Best would be a MCU with BLE that can receive RF packets at low power mode and use < 50µA in reception

Is that possible?

Thanks,

I forgot about BLE. Look at WB series. It is ultra low power and chip includes BLE:

ST declares up to 0,25 uA in Standby mode
