DA14681 Datasheet Bluetooth Low Energy 4.2 SoC

Manufacturer: Dialog Semiconductor (now Renesas)

Overview: DA14681 Bluetooth Low Energy 4.2 SoC FINAL General.

General Description

line batteries 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  Charger (up to 5.0 V) with programmable curves  High accuracy state-of-charge fuel gauge  Programmable threshold for brownout detection  Digitally controlled oscillators and PLL  16 MHz crystal oscillator  16 MHz RC oscillator  32 kHz crystal and RC oscillator delivering up to 84 DMIPS and provides a flexible  11.7 kHz RCX oscillator memory architecture, enabling code execution from  Low power PLL up to 96 MHz embedded memory (RAM, ROM) or non-volatile mem-  Three general purpose timer/counters with PWM ory (OTP or external Quad-SPI FLASH).

 One 16-bit up/down timer/counter with PWM 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.
