DA14581

Bluetooth Low Energy 4.2 SoC with Optimized Boot Time

FINAL

• All packet types (Advertising / Data / Control)

• Encryption (AES / CCM)

• Bit stream processing (CRC, Whitening)

• FDMA/TDMA/events formatting and synchronization

• Frequency hopping calculation

• Operating clock 16 MHz or 8 MHz

• Low power modes supporting 32.0 kHz or

32.768 kHz

• Supports power down of the baseband during the

protocol’s idle periods

• AHB Slave interface for register file access

• AHB Slave interface for Exchange Memory access

of CPU via BLE core

• AHB Master interface for direct access of BLE core

to Exchange Memory space

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

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.

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.
