DA14582
Bluetooth Low Energy 4.2 SoC with Audio CODEC
FINAL
General Description
 16 MHz 32 bit ARM Cortex-M0 with SWD I/F
The DA14582 integrated circuit has a fully integrated
radio transceiver, baseband processor for Bluetooth^®
low energy, and includes an audio CODEC.
 Dedicated Link Layer Processor
 AES-128 bit encryption Processor
 Memories
 32 kB One-Time-Programmable (OTP) memory
The DA14582 is optimized for remote control units
 42 kB System SRAM
(RCU) requiring support for voice commands and
 84 kB ROM
motion/gesture recognition. Its integrated analog wide
 8 kB Retention SRAM
band audio CODEC provides native support for analog
 Power management
microphones thereby reducing the total number of
 Integrated Buck DC-DC converter
components of the system while its optimized package
 P0, P1, P2 and P3 ports with 3.3 V tolerance
enables designs using single-layer FR1 PCBs further-
 Easy decoupling of only 4 supply pins
more contributing to the reduction of the cost of the
 Supports coin (typ. 3.0 V) and alkaline (typ. 1.5 V)
system.
battery cells
The DA14582 supports a flexible memory architecture
for storing Bluetooth profiles and custom application
code, which can be updated over the air (OTA). The
qualified Bluetooth low energy protocol stack is stored
in a dedicated ROM. All software runs on the ARM^®
Cortex^®-M0 processor via a simple scheduler.
 10-bit ADC for battery voltage measurement
 Digital controlled oscillators
 16 MHz crystal (±20 ppm max) and RC oscillator
 32 kHz crystal (±50 ppm, ±500 ppm max) and
RCX oscillator
 General purpose, Capture and Sleep timers
 Digital interfaces
The Bluetooth low energy firmware includes the
 29 General purpose I/Os
L2CAP service layer protocols, Security Manager
 2 UARTs with hardware flow control up to 1 MBd
(SM), Attribute Protocol (ATT), the Generic Attribute
 SPI+™ interface
Profile (GATT) and the Generic Access Profile (GAP).
 I2C bus at 100 kHz, 400 kHz
All profiles published by the Bluetooth SIG as well as
 3-axis capable Quadrature Decoder
custom profiles are supported.
