DA14581
Bluetooth Low Energy 4.2 SoC with Optimized Boot Time
FINAL
General Description
 AES-128 bit encryption Processor
The DA14581 integrated circuit is an optimized version
of the DA14580, offering a reduced boot time and sup-
porting up to 8 connections. It has a fully integrated
radio transceiver and baseband processor for Blue-
tooth^® low energy. It can be used as a standalone
application processor or as a data pump in hosted sys-
tems.
 Memories
 32 kB One-Time-Programmable (OTP) memory
 42 kB System SRAM
 84 kB ROM
 8 kB Retention SRAM
 Power management
 Integrated Buck/Boost DC-DC converter
 P0, P1 and P2 ports with 3.3 V tolerance
The DA14581 supports a flexible memory architecture
 Easy decoupling of only 4 supply pins
for storing Bluetooth profiles and custom application
 Supports coin (typ. 3.0 V) and alkaline (typ. 1.5 V)
code, which can be updated over the air (OTA). The
battery cells
qualified Bluetooth low energy protocol stack and the
 10-bit ADC for battery voltage measurement
HCI ready software are stored in a dedicated ROM. All
software runs on the ARM^® Cortex^®-M0 processor via
 Digital controlled oscillators
 16 MHz crystal (±20 ppm max) and RC oscillator
a simple scheduler.
 32 kHz crystal (±50 ppm, ±500 ppm max) and
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.
RCX oscillator
 General purpose, Capture and Sleep timers
 Digital interfaces
 Gen. purpose I/Os: 14 (WLCSP34), 24 (QFN40)
 2 UARTs with hardware flow control up to 1 MBd
 SPI+™ interface
 I2C bus at 100 kHz, 400 kHz
The transceiver interfaces directly to the antenna and
 3-axes capable Quadrature Decoder
is fully compliant with the Bluetooth 4.2 standard.
 Analog interfaces
The DA14581 has dedicated hardware for the Link
Layer implementation of Bluetooth low energy and
interface controllers for enhanced connectivity capabili-
ties.
 4-channel 10-bit ADC
 Radio transceiver
 Fully integrated 2.4 GHz CMOS transceiver
 Single wire antenna: no RF matching or RX/TX
switching required
Features
 Supply current at VBAT3V:
TX: 3.4 mA, RX: 3.7 mA (with ideal DC-DC)
 Complies with Bluetooth V4.2, ETSI EN 300 328 and
 0 dBm transmit output power
EN 300 440 Class 2 (Europe), FCC CFR47 Part 15
 -20 dBm output power in “Near Field Mode”
(US) and ARIB STD-T66 (Japan)
 -93 dBm receiver sensitivity
 Supports up to 8 Bluetooth low energy connections
 Packages:
 Fast cold boot in less than 30 ms
 Ultra-Thin WLCSP 34 pins, 2.436 mm x 2.436 mm
 Processing power
x 0.334 mm
 16 MHz 32 bit ARM Cortex-M0 with SWD inter-
 WLCSP 34 pins, 2.436 mm x 2.436 mm
face
x 0.511 mm
 Dedicated Link Layer Processor
 QFN 40 pins, 5 mm x 5 mm
