UNCTIONAL
The BL600 BLE module is a self-contained Bluetooth Low Energy product and requires only power and a user's
smart
BASIC 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
binds the sensors to the BLE wireless functionality.
The variety of hardware interfaces and the
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.

5.1 Power management (includes brown-out and power on reset)

Power management features:
System Standby Doze / Deep Sleep modes.

Brownout Reset.

Open /Close Peripherals (UART, SPI, I2C, SIO's and ADC). Peripherals consume current when open; each

peripheral can be individually closed to save power consumption (with a command in
application script).
2-region RAM retention (No RAM retention in Deep Sleep mode).

Enable DCDC on power-up if VCC is >2.1V, see Note1.

smart
BASIC command allows the VCC voltage to be read (through the internal ADC).

Pin wake-up system from Deep sleep (since

Power supply features:
Supervisor HW to manage power on reset, brownout (and power fail).

1.8V to 3.6V supply range using internal LDO regulator.

2.1 to 3.6V supply range using internal DCDC convertor, see Note1.

smart
Note1: With
internal DCDC convertor was switched off on recommendation of the chipset provider until
future notice. The benefits of re-adding the DCDC feature (in the future) include:
- The DCDC convertor could be disabled when supply voltage drops to below 2.1V so LDO can
be used for low supply voltages.
- When enabled, DCDC operation would automatically suspend when only the internal low
current LDO is needed. This feature is useful for applications using battery technologies with
higher nominal cell voltages. The reduction in supply voltage level from a high voltage to a low
voltage reduces the peak power drain from the battery. Used with a 3 V coin-cell battery, the
peak current drawn from the battery is reduced by approximately 30% (with DCDC enabled).
