The Renesas Smart Asset Tracking Label leverages Renesas ultra-low power devices to provide package or asset tracking combined with environmental data logging in an ultra-thin, flexible and easily disposable device. The Smart Asset Tracking Label design is based on the DA14531 ultra-low power Bluetooth® Low-Energy (LE) 5.1 SoC with an Arm Cortex-M0+ MCU, an integrated PMU supporting buck and boost mode and a variety of peripheral functions that allows the DA14531 to maximize battery life while running from e.g. print Zink-Ploy, single SilverOxide, 1S or 2S alkaline or standard 3V button cells of all sizes. The label is powered from a printed, flexible and disposable battery that’s directly connected to the DA14531 integrated Power Management Unit and helps to gain the maximum lifespan from the battery through its state-of-the-art power management and especially it inrush current control. The label includes various sensors, including the high accuracy and low power HS3001 temperature and humidity sensor. The firmware and data can be stored in the ultra-low active power AT25EU SPI Flash device, which offers the lowest active energy consumption during erase, write and read operation. For applications not requiring data logging, the DA14531 BLE SoC firmware can be stored in the integrated OTP memory to minimize the BOM.
