description Dialog DA14531 Overview

The Dialog DA14531 is a Bluetooth 5.1 System on Chip designed for low power wireless connectivity. It utilizes mesh networking capabilities, enabling multiple devices to communicate efficiently. This SoC is particularly well-suited for applications requiring long battery life such as beacon devices and sensor networks operating with coin-cell batteries. It’s commonly used in secure IoT (SOC) solutions where reliable Bluetooth mesh performance is essential.

help Dialog DA14531 FAQ

What is the Dialog DA14531 used for?

The DA14531 is a Bluetooth Low Energy 5.1 system-on-chip with a 2.4 GHz transceiver and a 16 MHz Arm Cortex-M0+ microcontroller. Renesas documents 48KB of retainable RAM, 32KB of one-time-programmable memory, and applications such as beacons, sensors, trackers, and small human-interface devices. [Renesas DA14531 datasheet](https://www.renesas.com/en/document/dst/da14531-datasheet)

Does the DA14531 support Bluetooth Mesh networking?

The chip provides Bluetooth LE 5.1 profiles and can support up to three LE connections, but mesh depends on the software stack, SDK, memory budget, and topology. Do not treat the catalog's mesh wording as proof that a finished mesh product will work without checking the Renesas SDK.

How low is the DA14531's power consumption for battery devices?

Renesas lists clock-less hibernation current of about 270 nA in buck mode and 240 nA in boost mode. The datasheet also lists typical system currents of 3.5 mA for transmit and 2.2 mA for receive at 0 dBm, 3 V, and the integrated power converter.

What is the difference between DA14531-00 and DA14531-01?

The DA14531-00 supports central and peripheral roles plus observer functions, while the DA14531-01 is optimized for peripheral-only applications. Renesas says the -01 provides about 25 percent more user RAM for a typical BLE application and remains pin-compatible.
