FINAL
4.2.2 Radio Transceiver
The Radio Transceiver implements the RF part of the
Bluetooth low energy protocol. Together with the Blue-
tooth 4.2 PHY layer, this provides a 93 dB RF link bud-
get for reliable wireless communication.
All RF blocks are supplied by on-chip low-drop out-reg-
ulators (LDOs). The bias scheme is programmable per
block and optimized for minimum power consumption.
The Bluetooth LE radio comprises the Receiver, Trans-
mitter, Synthesizer, Rx/Tx combiner block, and Biasing
LDOs.
Features
• Single ended RFIO interface, 50  matched
• Alignment free operation
• -93 dBm receiver sensitivity
• 0 dBm transmit output power
• Ultra low power consumption
• Fast frequency tuning minimizes overhead
Figure 4: SmartSnippets Stack
Apart from the protocol stack, the Software platform
supports a Hardware Abstraction Layer (HAL) which
enables easy access to peripheral’s features from a
programmer’s point of view, as presented in the follow-
ing figure.
4.2.3 SmartSnippets
The DA14580 comes complete with Dialog’s Smart-
Snippets Bluetooth Software platform which includes
a qualified Bluetooth Smart single-mode stack on chip.
Numerous Bluetooth Smart profiles for consumer well-
ness, sport, fitness, security and proximity applications
are supplied as standard, while additional customer
profiles can be developed and added as needed.
The SmartSnippets software development environ-
ment is based on Keil’s uVision mature tools and
contains example application code for both embedded
and hosted modes.
