Abstract

R-mobile U2 integrates an application processor and an LTE-capable triple-band baseband processor in 28-nm technology to provide rich content to the mid-range market. Several power-management techniques are equipped, including a low-leakage power switch, dual-standby mode static RAM (SRAM), and frequency control for maximum power suppression.
