World’s first Wearable-on-Chip Bluetooth Smart Device

first_imgDialog Semiconductor has released details on the World’s first ‘Wearable-on-Chip’ Bluetooth Smart (v4.2) device. The DA14680 SmartBond chip is a small, ultra-low power circuit that integrates all the functions to create fully hosted wearable computing products with excellent battery life. It features flexible processing power, flash memory for virtually unlimited execution space, dedicated circuitry for sensor control, analogue and digital peripherals optimised for wearable products, and an advanced power management unit. The DA14680 eliminates several external chips from wearable product design, facilitating smaller form factors, low system cost and low power consumption.With its feature-rich functionality, small size and low power, the DA14680 will also address emerging IoT applications. The wearable market is predicted to reach approximately 170 million active units by 2019.The DA14680’s ultra-low power 30uA/MHz ARM Cortex-M0 application processor may be programmed to a maximum clock frequency of 96 MHz. Security features include a dedicated hardware crypto engine with elliptic curve cryptology (ECC), delivering end-to-end banking-level encryption, ensuring personal data security. The device integrates 8 Mbit flash memory, audio support with PDM and I2S/PCM interfaces, two separate I2C and SPI buses, three white LED drivers, a temperature sensor, multi-channel DMA, and an 8-channel, 10-bit ADC. Intelligent power management, including system power rails and a Li-ion/LiPo battery charger and fuel gauge are also on-chip. Its development is accelerated using Dialog’s SmartBond development kits. These include the SmartSnippets software development environment, example application code and a power profiler for real-time, power-optimised coding. The DA14680 will be sampling in the second quarter of 2015.last_img
