Introduction to DA14580
Dialog's SmartBond DA14580 Bluetooth Smart System-on-Chip (SoC), the world's lowest power and smallest footprint, extends the battery cruising time of smart phone accessories with applications or computer peripherals compared to competing solutions. Times. The chip is designed to wirelessly connect a keyboard, mouse or remote control to a tablet, laptop or smart TV; enabling consumers to use innovative applications on smartphones and tablets Connect with watches, wristbands or smart labels to achieve various functions such as “self-assessment†of health and physical condition, and finding lost keys.
SmartBond is the first Bluetooth smart solution to break the 4mA wireless transceiver current limit, allowing designers to double the battery life of their products or reduce the number and size of batteries required. Its unique low-power architecture consumes only 3.8mA of wireless transmit and receive current, 50% lower than other Bluetooth smart solutions on the market, and its deep sleep mode current is less than 600nA. This means that in a product that sends 20 bytes per second, a 225mAh coin cell battery can keep it running for 4 years and 5 months; compared to previous generations of Bluetooth smart technology can only last 2 years.
The DA14580 has a power management block with a DC-DC converter and all necessary LDOs to reduce the need for external components and the total bill of materials. By precisely turning the power to each chip on and off, Dialog can minimize power consumption. SmartBond's operating voltage can be reduced to an unprecedented 0.9V, enabling the use of an alkaline or nickel-manganese battery to operate a computer or smart TV peripheral. In the past, two batteries were required. This opens the door to numerous new design ideas for designers, enabling them to develop ultra-compact and new-sized products while reducing the total cost of the system. Energy harvesting technologies, such as collected light or kinetic energy, can also be used to charge Rechargeable Batteries that support system operation.
The DA14580 has a built-in 32-bit ARM Cortex M0 core and a one-time programmable (OTP) built-in on-chip flash memory that provides extreme design flexibility, eliminates the need for an external processor and reduces cost. Dialog has begun working with Murata, the world's leading wireless module manufacturer, to develop small modules that allow existing designers with less knowledge of RF systems to quickly integrate certified solutions into their products.
