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 300 328 and EN Flexible Reset Circuitry 300 440 Class 2 (Europe), FCC CFR47 Part 15 (US) and System & Power On Reset in a single pin ARIB STD-T66 (Japan) General purpose, Capture and Sleep timers Supports up to 8 Bluetooth LE connections Digital interfaces Fast cold boot in less than 50 ms Gen. purpose I/Os: 14 (WLCSP34), 25 (QFN40), 32 Processing power (QFN48) 16 MHz 32 bit ARM Cortex-M0 with SWD interface 2 x UARTs with hardware flow control up to 1 Mbps Dedicated Link Layer Processor SPI+ interface AES-128 bit encryption Processor I2C bus at 100 kHz, 400 kHz Memories 3-axes capable Quadrature Decoder 64 kB One-Time-Programmable (OTP) memory Analog interfaces 96 kB Data/Retention SRAM 4-channel 10-bit ADC 128 kB ROM Radio transceiver Power management Fully integrated 2.4 GHz CMOS transceiver Integrated Buck/Boost DCDC converter Single wire antenna: no RF matching or RX/TX switching required P0, P1 and P2 ports with 3.3 V tolerance Easy decoupling of only 4 supply pins Supply current at VBAT3V: 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 oscillator WLCSP 34 pins, 2.40 mm x 2.66 mm 32 kHz crystal (50 ppm, 500 ppm max) and RCX QFN 40 pins, 5 mm x 5 mm oscillator QFN 48 pins, 6 mm x 6 mm Applications Voice-controlled remote controls Beacons Datasheet Revision 3.3 15-Oct-2018 CFR0011-120-00 1 of 340 2018 Dialog Semiconductor DA14585 Bluetooth 5.0 SoC with Audio Interface (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 3.3 15-Oct-2018 CFR0011-120-00 2 of 340 2018 Dialog Semiconductor
