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

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.
