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)

1360 uA (= 1140 uA <base current> + 220 uA)

SPI (master, 8 Mbps

1340 uA (=1140 uA <base current> 200uA).

I2C (400 kbps)

1540 uA (=1140 uA <base current> + 400 uA)

ADC

1430 uA (=1140 uA <base current> + 290 uA)

For the BL600-Sx-04 would consume total for each peripheral of:

UART (115.2 kbps)

1030 uA (= 810 uA <base current> + 220 uA)

SPI (master, 4 Mbps

1010 uA (= 810 uA <base current> 200 uA)

I2C (400 kbps)

1210 uA (= 810 uA <base current> 400 uA)

ADC

1070 uA (= 810 uA <base current> + 260 uA)

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 smartBASIC application script) resulting in the base 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 smartBASIC application script) when needed, resulting in current saving (no base

current consumption penalty). Similar argument for ADC (open ADC when needed).

FUNCTIONAL DESCRIPTION

The BL600 BLE module is a self-contained Bluetooth Low Energy product and requires only power and a user’s

smartBASIC application to implement full BLE functionality. The integrated, high performance antenna

combined with the RF and Base-band circuitry provides the Bluetooth Low Energy wireless link, and any of the

SIO lines provide the OEM’s chosen interface connection to the sensors. The user’s smartBASIC application binds

the sensors to the BLE wireless functionality.

The variety of hardware interfaces and the smartBASIC programming language allow the BL600 module to serve

a wide range of wireless applications, whilst reducing overall time to market and the learning curve for

developing BLE products.

To provide the widest scope for integration a variety of physical host interfaces / sensors are provided. The

major BL600 series module functional blocks described below.
