Current consumption

Characteristics measured over recommended operating conditions unless otherwise

specified. Typical value are referred to TA = 25 °C, VIN = 3.0 V.

Current consumption values has been taken using the “BlueNRG current consumption

estimation tool”, configured to match the SPBTLE-1S configuration.

The tool is available on ST.com at:

http://www.st.com/en/embedded-software/stsw-bnrg001.html

Reported values have been taken configuring the tool as shown in the follow figure:

a The HS_Startup_Time has been measured according to the “Bringing up the BlueNRG-1 device” (AN4818). The

HS_Startup_Time parameter is important because it permits minimization of the current consumption. A value that

is too short prevents the SPBTLE-1S from correctly sending/receiving packets. Users should set the typical value

as indicated in Table 3.
