IoT Platform
YouSiP-IoT is a comprehensive platform solution designed for emerging application as IoT based on SMIC 55nm low leakage (LL) and 130nm Mixed signal Low leackage(LL) process which can provide embedded non-volital flash memory as well. This solution integrates ARM Cortex Mx series MCU and CEVA TeakLite or MM series DSP, involves WiFi, Bluetooth/BLE interfaces, which can connect to a series of different sensors. YouSiP-IoT platform can assist customer to reduce the processing delay time, enhance the data security, improve the data rate and reduce power consumption of their SoC design, which is adopted in battary power supply environment as smart home, IoT and wearable devices with excellent low power managment.

Low Power Design For IoT
Power Management Unit (PMU) for IoT
General Description
Power-consumption will affect the IoT’s functionality, and power management has become one of the most important and differentiating feature in the low power application such as wearable. Many devices have multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power to charge their batteries including USB. Brite's Power Management Unit (PMU) provides high efficiency power conversion that minimizes energy loss, and is used in battery-powered devices, smart appliances, healthcare, home automation, consumer electronics, industrial automation.
