10 / 155 page  Datasheet Revision 3.4 09-Nov-2016 CFR0011-120-00-FM 10 of 155 © 2014 Dialog Semiconductor DA14580 Bluetooth Low Energy 4.2 SoC 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 budget 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.
