SOC chip, software, and hardware development kit for wearable-design by MediaTek
After the Qualcomm’s turn, its now the MediaTek focusing on the wearable electronics market. MediaTek is making available chips, software, and hardware development kit for quickly designing the popular wearable devices. MediaTek is offering a new Hardware Development Kit and expanded it’s LinkIt development platform for RTOS.
The new Hardware Development Kit is based on the MediaTek MT2523G Chipset. MT2523G has MCU, low power GNSS , dual mode Bluetooth, and a power management unit (PMU). The microcontroller unit is an ARM Cortex M4 with floating point MCU, integrated with 4MB PSRAM and 4MB flash memory. MT2523 provides interfaces such as UART, I2C, SPI, I2S, PWM, SDIO, MSDC, USB, PCMIF, ADC and dual digital MIC.
The Hardware Development Kit is developed by Silicon Application Corp. The Kit with dual-mode Bluetooth, GPS support such as GNSS standards support can be used to design wearable devices such as smartwatches, fitness trackers, health monitors, and any such wearable devices including emergency locators.
This 2nd new Kit for its LinkIt Development Platform for RTOS takes the support of the platform’s common tool chain and set of APIs. So that this common tool chain and set of APIs can be leveraged across. By using the MediaTek LinkIt SDK v4 on this HDK, the developers can develop the products which are smaller and efficient according to MediaTek. The new SDK is also updated with efficient Bluetooth stack and other improvements to support the MT2523 chipset variants.
The Key features available in the Hardware Development Kit includes:
Dual-mode Bluetooth 2.1 + EDR and Bluetooth 4.2 Low Energy with integral antenna.
Fast, low-power, high-precision positioning with integral HDK antenna for GPS and SMA connector for GLONASS, Galileo and BeiDou.
Integrated display and versatile peripheral options, including I2C, master and slave SPI, master and slave I2S, PCM, UART, 12-bit ADC and PWM which can be used for a broad range of wearables, including smartwatches, fitness trackers and wristbands incorporating various sensors.
Low power consumption achieved by highly integrated SoC using 55nm ultra-low power (ULP) technology from TSMC with Power Management Integrated Circuit (PMIC), and multiple frequency and voltage modes.
Flexible power options for external battery and USB (5V) charger.
Additional onboard memory (eMMC) or the option to use a microSD card.
The Key features of the LinkIt Development Platform for RTOS as said by the MediaTek includes:
Based on the popular FreeRTOS with additional open-source modules (source code available).
Supports chipsets based on the ARM Cortex-M4 architecture, offering high performance, low power connectivity.
Supports multiple chipsets/hardware, including the MT7687F Wi-Fi SoC and the MT2523 Bluetooth/GNSS chipset family.
Development and debugging in ARM Keil µVision, IAR Embedded Workbench and GCC.
