DA14580 Introduction

Dialog launched the world's lowest, smallest smartbond DA14580 Bluetooth intelligent system-level chip (SoC), compared to the competitive solution, the product can be equipped with the application of intelligent mobile phone accessories, or computer peripheral products, battery cruising time extended by one times. The chip is designed to connect a keyboard, mouse or remote with a tablet, notebook or smart TV wirelessly, allowing consumers to connect to a watch, wrist, or smart label through a variety of innovative applications on smart phones and tablets, such as "self-assessment" health and physical conditions, and find a variety of functions such as missing keys.

The Smartbond is the first Bluetooth smart solution to break the 4mA wireless current limit, allowing designers to extend the battery life of a product by a factor, or reduce the number and size of required batteries. Its unique low-power architecture consumes only 3.8mA of wireless transceiver Current, 50% less than other Bluetooth smart solutions on the market, and its deep sleep mode currents are below 600nA. This means that in a product that sends 20 bytes per second, a 225mAh coin cell can keep it running for 4 years and 5 months, compared to a previous generation of Bluetooth smart technology that lasts only 2 years.

The DA14580 has a power management Area block that includes a DC-to converter and all the necessary ldos to reduce the need for external components as well as the total bill of materials. The dialog is able to minimize power consumption by accurately opening and closing the power of each chip block. The operating voltage of the smartbond can be reduced to an unprecedented 0.9V, enabling the use of an alkaline or Ni-mn battery to operate a computer or smart TV peripheral product, which in the past requires two batteries. This opens the door for designers to countless new design ideas, enabling them to develop ultra-tight and new-size products while reducing the total cost of the system. Energy harvesting techniques, such as the collected light or kinetic energy, can also be used to charge rechargeable batteries that support the operation of the system.

DA14580 built-in a 32-bit ARM Cortex M0 inner core, and a one-time programmable (OTP) built-in flash on the chip, they provide extremely high design flexibility, eliminating the need for external processors and reducing costs. Dialog has started working with the world's leading wireless module manufacturer, Murata, to develop small modules that enable designers with less knowledge of RF systems to quickly integrate certified solutions into their products.

The advantage lies

The longest battery life

The DA14580 's transceiver current is only 4.9 ma--50% lower than other Bluetooth smart solutions of its kind, which means that its battery life has been extended by a factor. In addition, the operating voltage of the DA14580 is as low as 0.9V: It is the best choice for collecting energy in a fully automatic control system.

Small size

The DA14580 is packaged in wafer-level wafer size, with a minimum size of 2.5 x 2.5 x 0.5 mm and requires only 5 external components, with a alkaline, nickel-manganese or coin-cell battery-giving the user the smallest and most distinctive product available.

Minimized system costs

The high level of integration of the DA14580 (including an embedded 32-bit MCU, memory, and rich peripherals) ensures a minimum number of external components. Combined with the ability to integrate power management devices and smaller batteries, this product minimizes material costs (BOM), allowing you to develop low-cost, high-performance systems.

Simplified design

As one of the smartbond™ products, the DA14580 is designed to be extremely simple, without the need for an external MCU to support fully managed applications, with a complete development environment and dialog smartsnippets™ software support. In addition, the DA14580 can be used in compact, fully certified modules, accelerating time-to-market and eliminating the need for RF expertise.
