Overview
Description
Module available: DA14535MOD
The DA14535 is an ultra-low power SoC integrating a 2.4GHz transceiver and an Arm® Cortex®-M0+ microcontroller with a RAM of 64kB and a One-Time Programmable (OTP) memory of 12kB. It can be used as a standalone application processor or as a data pump in hosted systems. The radio transceiver, the baseband processor, and the qualified Bluetooth® low energy stack are fully compliant with the Bluetooth Low Energy 5.3 standard.
Ultra-low power can be achieved using the integrated low IQ buck-boost DC/DC, which is on during sleep in buck mode.
The low system cost is achieved through the high level of integration: A complete Bluetooth Low Energy system can be achieved with the addition of six tiny external passives, a crystal, and a power source. And to lower the barrier of entry, DA14535 is also available in an easy-to-use tiny module incorporating all the needed components, making the addition of Bluetooth Low Energy to any application a simple drop-in.
Extended operating temperature range up to 105 °C and extended output power up to 4dBm enable DA14535 to support a wide range of industrial applications, next to connected health, consumer, and IoT applications. Available in a tiny 2.2mm x 3.0mm FCGQFN24 package, the DA14535 is pin-to-pin compatible with its predecessors, DA14531 and DA14530. And, it is complemented by a flexible SDK supporting major compilers such as Keil and GCC out of the box.
Features
- Future-proof, compliant with Bluetooth 5.3 (core)
- Optimized for disposable products in connected medical, connected consumer, and industrial applications
- Designed to work with disposable, even printed batteries
- Works well with the smallest capacity batteries, <30mAh
- Supports multiple years of shelf life
- Inrush current can be limited for disposable batteries with high internal resistance.
- Package design allows for low-cost manufacturing with the smallest possible footprint
- Only requiring a single 32MHz crystal
- In bypass mode, no DC/DC inductor is required
- No boost converter is required when working with 1.5V batteries
- Production Line Tool for accelerated production ramp up, resulting in faster time to market and shortest production test time per device

Does DA14535 Support LE Audio and ISO related CIG/BIS HCI Commands?
... provided in SDK6.0.22.1401? Or is it a limitation of the DA14535 hardware itself, meaning it doesn't support ISO or LE Audio features at all? What is the latest version of HCI firmware that can be flashed on to DA14535 ? Thank you in advance for your help!
