DA14582
Low Power Bluetooth Smart SoC with Audio Codec
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^®
Smart with Audio Codec.

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 Smart protocol stack is stored in a
dedicated ROM. All software runs on the ARM® Cor-
tex®-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 Smart firmware includes the L2CAP ser-
 29 General purpose I/Os
