ADC current during conversion
The above current consumption is for the particular peripheral only and to operate that peripheral requires
some other internal blocks which consume fixed amount of base current (~740uA). Nordic silicon used in
BL600-Sx0-2, BL600-Sx-03, this fixed base current is bit higher (by ~400uA). This base current of ~1140 uA (=
~740uA+400uA) is consumed when the UART, SPI, I2C, or ADC is opened (operated). Therefore BL600-Sx-02
and BL600-Sx-03 would consume total for each peripheral of:
UART (115.2 kbps)
SPI (master, 8 Mbps
I2C (400 kbps)
ADC
For the BL600-Sx-04 would consume total for each peripheral of:
UART (115.2 kbps)
SPI (master, 4 Mbps
I2C (400 kbps)
ADC
For asynchronous interface like the UART (asynchronous as the other end can communicate at any time), the
UART (on BL600) must kept open (by a command in
current consumption penalty.
For synchronous interface like the I2C or SPI (since BL600 side is the master), the interface can be closed and
opened only (by a command in
base current consumption penalty). Similar argument for ADC (open ADC when needed).
