DA14585 Bluetooth 5.0 SoC with Audio Interface General Description The DA14585 is an ultra-low power SoC integrating a 2.4 GHz transceiver and an ARM Cortex-M0 microcontroller with 96kB of RAM and 64kB of One-Time Programmable (OTP) memory. It offers a very fast boot time (<50ms) and supports up to 8 BLE connections. It can be used as a standalone application processor or as a data pump in hosted systems. The radio transceiver, the baseband processor and the qualified Bluetooth LE stack is fully compliant with the Bluetooth Low Energy 5.0 standard. The DA14585 has dedicated hardware for the Link Layer implementation of Bluetooth Low Energy and interface controllers for enhanced connectivity capabilities. The Bluetooth Low Energy firmware includes the L2CAP service layer protocols, Security Manager (SM), Attribute Protocol (ATT), the Generic Attribute Profile (GATT) and the Generic Access Profile (GAP). All profiles published by the Bluetooth SIG as well as custom profiles are supported. The device is suitable for remote control units (RCU) requiring support for voice commands, wireless sensor nodes, Bluetooth Mesh applications, fitness trackers, toys and HID devices (keyboards, mice, etc.). Key Features Complies with Bluetooth V5.0, ETSI EN 300 Flexible Reset Circuitry 328 and EN 300 440 Class 2 (Europe), FCC System & Power On Reset in a single pin CFR47 Part 15 (US) and ARIB STD-T66 General purpose, Capture and Sleep timers (Japan) Digital interfaces Supports up to 8 Bluetooth LE connections Gen. purpose I/Os: 14 (WLCSP34), 25 Fast cold boot in less than 50 ms (QFN40), 32 (QFN48) Processing power 2 x UARTs with hardware flow control up 16 MHz 32 bit ARM Cortex-M0 with SWD to 1 Mbps interface SPI+ interface Dedicated Link Layer Processor I2C bus at 100 kHz, 400 kHz AES-128 bit encryption Processor 3-axes capable Quadrature Decoder Memories Analog interfaces 64 kB One-Time-Programmable (OTP) 4-channel 10-bit ADC memory Radio transceiver 96 kB Data/Retention SRAM Fully integrated 2.4 GHz CMOS 128 kB ROM transceiver Power management Single wire antenna: no RF matching or Integrated Buck/Boost DCDC converter RX/TX switching required P0, P1 and P2 ports with 3.3 V tolerance Supply current at VBAT3V: Easy decoupling of only 4 supply pins TX: 3.4 mA, RX: 3.7 mA (with ideal DC- DC) Supports coin (typ. 3.0 V) and alkaline (typ. 1.5 V) battery cells 0 dBm transmit output power 1.8 V cold boot support -20 dBm output power in Near Field Mode 10-bit ADC for battery voltage measurement -93 dBm receiver sensitivity Digital controlled oscillators Packages: 16 MHz crystal (20 ppm max) and RC WLCSP 34 pins, 2.40 mm x 2.66 mm oscillator QFN 40 pins, 5 mm x 5 mm 32 kHz crystal (50 ppm, 500 ppm max) QFN 48 pins, 6 mm x 6 mm and RCX oscillator Datasheet Revision 3.2 04-Apr-2018 CFR0011-120-00 1 of 340 2018 Dialog Semiconductor DA14585 Bluetooth 5.0 SoC with Audio Interface Applications Voice-controlled remote controls Beacons (Multi-sensor) Wearable devices Fitness trackers Consumer health Smartwatches Human interface devices Keyboard Mouse Toys Consumer appliances Key Benefits Lowest power consumption Smallest system size Lowest system cost System Diagram Figure 1: System Diagram Datasheet Revision 3.2 04-Apr-2018 CFR0011-120-00 2 of 340 2018 Dialog Semiconductor
