Renesas — DA14695 Bluetooth Wireless Module

Renesas has launched a fully integrated wireless module which provides a ready-made way to implement Bluetooth® Low Energy networking, accelerating time-to-market and reducing design risk.

Based on the SmartBond DA14695 Bluetooth Low Energy v5.2 system-on-chip (SoC), the DA14695MOD integrates all the passive components required for a Bluetooth radio, along with an antenna and 32 Mbits of quad SPI Flash memory. The module is backed by an easy-to-use software development suite.

Particularly well suited to systems powered by a rechargeable battery, the DA14695 Module features a built-in JEITA-compliant USB charger including fuel gauge. It is supplied in a compact surface-mount package which measures 20 mm x 15.9 mm x 2.5 mm.

The DA14695 SoC on which the module is based is centered on an Arm® Cortex®-M33 microcontroller core with floating-point unit and DSP extensions. The SoC includes advanced power management functions, a cryptographic security engine, display controller, and analog and digital peripherals. The DA14695 SoC also features a Cortex-M0+ core that runs the software-configurable Bluetooth v5.2 media access controller and radio.

A programmable sensor node controller runs sensor node operations and data acquisition without intervention by the Cortex-M33 CPU, resulting in very low power consumption. The advanced power management unit in the DA14695 enables it to run on primary or rechargeable batteries, as well as to provide power to external devices through the integrated dc-dc converter and integrated LDOs.
