  • Realizing high display quality, even with low power consumption


    TOKYO – Toshiba Corporation (TOKYO: 6502) today announced the launch of "TZ1201XBG", an application processor for wearable devices, as the latest addition to its ApP Lite™ family for the Internet of Things (IoT). Samples of the TZ1201XBG ApP Lite processor will begin shipping in April and mass production is scheduled to begin in summer 2016. The TZ1201XBG will be showcased at the 2016 International Consumer Electronics Show (CES), to be held from January 6 to January 9 in Las Vegas, U.S.A.

    The TZ1201XBG integrates an ARM® Cortex®-M4F processor and is designed to operate at active current consumption of 78-microamps per megahertz (MHz) in normal operation mode. It works with the power management software for about one week in pulse measurement applications or for about one month in watch applications with a 200mAh battery.

    The TZ1201XBG’s dedicated 2D graphics accelerator reduces CPU utilization and power dissipation, enabling smooth functioning of the graphical user interface (GUI). Integrated audio interfaces for voice command[1] and voice trigger processing[2], and 2D graphics accelerator ensure customers enjoy the high level of user experience.

    Compared with previous models, the improved high-precision Analog Front End circuit (AFE) can measure extremely weak signals (about 10 microvolts), such as EEG or EMG (brain and muscle scans, respectively), as well as impedance, which can be used to determine stress levels by calculating skin resistance. The AFE also supports up to 4-channel voltage/current/impedance multi-sensing with only a minimal addition of external components. By integrating the software and various services, the data measured by the AFE can be utilized to create new applications as well as new market targets.

    In addition to 2.2MB of integrated high-capacity SRAM, the TZ1201XBG incorporates e・MMC™[3]/SDIO interfaces that support external memory ICs such as SPI NOR, SPI NAND and e・MMC™. This support provides designers with the flexibility to specify the most suitable memory ICs and capacities for their devices. Together with the embedded data compressor, the TZ1201XBG enables high-capacity data storage for long periods of time without frequent data uploads.
