M31 low power solution is comprehensive for low power designs including the green memory, low VCCMIN memory, low power cell library, Ultra-Low Power Fractional PLL (ULFPLL), and low power interface IP like USB 2.0 and USB 1.1. M31 green memory provides low power modes including standby, nap, retention, and power shutdown. The dual rail architecture is also built in the green memory for dynamic frequency and voltage scaling. M31 low VCCMIN memory supports low voltage operation to reduce leakage and dynamic power directly. In order to achieve low power SoC design, M31 low power cell library is the critical component. Not only low power optimized cells but also power management kits are included.
M31 Ultra-Low Power Fractional PLL (ULFPLL) can operate at very low voltage (0.7V) and provide a reliable clocking source for SoC. M31 low power USB 2.0 and USB 1.1 IP are optimized for IoT applications and can save more than 30% operating current and 70% stand-by current.
