AA battery powerable Bluetooth Smart SoC from Dialog consumes only 3.8mA

Dialog Semiconductor plc has launched Bluetooth SoC chip called SmartBond (part number DA14580). Dialog claims DA14580 is the world’s lowest power and smallest IC which more than doubles the battery life of an app-enabled smartphone accessory or computer peripheral in comparison to competing solutions on the market. DA14580 targeted for designing wireless interface devices such as keyboards, mice and remote controls for tablets, laptops or Smart TVs. The devices using this Bluetooth chip can enable consumers to use innovative new apps on their smartphones and tablets connected with watches, wristbands and smart tags to “self-track” their health and fitness levels, locate lost keys and much more besides, suggest Dialog. 32-bit ARM Cortex M0 and OTP memory powered DA14580 draws as little as 3.8mA at transmission and reception, a 50% less current than other Bluetooth Smart solutions on the market, as per Dialog. The deep sleep current is under 600nA. This means a 225mAh coin-cell battery in a product sending 20 bytes of data per second would last 4 years and 5 months in comparison to just 2 years with previous generations of Bluetooth Smart technology, explains Dialog. The DA14580 has on-chip DC-DC converter and all the necessary LDOs and works at VCC down to 0.9V so that just a single alkaline or NiMH cell AA battery can be used to power wireless device.
