DA14681 Product details

General description
The DA14681 is a flexible System-on-Chip combining
an application processor, memories, cryptography
engine, power management unit, digital and analog
peripherals and a Bluetooth Low Energy MAC engine
and radio transceiver.
The DA14681 is based on an ARM® Cortex®-M0 CPU
delivering up to 84 DMIPS and provides a flexible
memory architecture, enabling code execution from
embedded memory (RAM, ROM) or non-volatile memory (OTP or external Quad-SPI FLASH).
The advanced power management unit of the
DA14681 enables it to run from primary and secondary
batteries, as well as provide power to external devices.
The on-chip charger and state-of-charge fuel gauge
allow the DA14681 to natively charge rechargeable
batteries over USB.
An on-chip PLL enables on-the-fly tuning of the system
clock between 32 kHz and 96 MHz to meet high processing requirements. Several optimised sleep modes
are available to reduce power dissipation when there is
no activity.
