DA14581 fiche technique
DA14581
Low Power Bluetooth Smart 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® Smart. It can be used as a standalone applica-
tion processor or as a data pump in hosted systems.
Memories
32 kB One-Time-Programmable (OTP) memory
42 kB System SRAM
84 kB ROM
8 kB Retention SRAM
Power management
Integrated Buck/Boost DCDC converter
The DA14581 supports a flexible memory architecture
P0, P1 and P2 ports with 3.3 V tolerance
for storing Bluetooth profiles and custom application
Easy decoupling of only 4 supply pins
code, which can be updated over the air (OTA). The
Supports coin (typ. 3.0 V) and alkaline (typ. 1.5 V)
qualified Bluetooth Smart protocol stack and the HCI
battery cells
ready software are stored in a dedicated ROM. All soft-
ware runs on the ARM® Cortex®-M0 processor via a
10-bit ADC for battery voltage measurement
Digital controlled oscillators
simple scheduler.
16 MHz crystal (±20 ppm max) and RC oscillator
The Bluetooth Smart firmware includes the L2CAP ser-
vice layer protocols, Security Manager (SM), Attribute
Protocol (ATT), the Generic Attribute Profile (GATT)
and the Generic Access Profile (GAP). All profiles pub-
lished by the Bluetooth SIG as well as custom profiles
are supported.
32 kHz crystal (±50 ppm, ±500 ppm max) and
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
The transceiver interfaces directly to the antenna and
I2C bus at 100 kHz, 400 kHz
is fully compliant with the Bluetooth 4.1 standard.
3-axes capable Quadrature Decoder
The DA14581 has dedicated hardware for the Link
Layer implementation of Bluetooth Smart and interface
controllers for enhanced connectivity capabilities.
Analog interfaces
4-channel 10-bit ADC
Radio transceiver
Fully integrated 2.4 GHz CMOS transceiver
Features
Single wire antenna: no RF matching or RX/TX
switching required
Complies with Bluetooth V4.1, ETSI EN 300 328 and
Supply current at VBAT3V:
EN 300 440 Class 2 (Europe), FCC CFR47 Part 15
TX: 3.4 mA, RX: 3.7 mA (with ideal DC-DC)
(US) and ARIB STD-T66 (Japan)
0 dBm transmit output power
Supports up to 8 Bluetooth Smart connections
-20 dBm output power in “Near Field Mode”
Fast cold boot in less than 30 ms
-93 dBm receiver sensitivity
Processing power
Packages:
16 MHz 32 bit ARM Cortex-M0 with SWD inter-
WLCSP 34 pins, 2.436 mm x 2.436 mm
face QFN 40 pins, 5 mm x 5 mm
Dedicated Link Layer Processor
