Description
The STV0984 is a new generation, ultra low power Megapixel digital image processor designed to fit into mobile applications. STV0984 comes with support for 2 SMIA sensor heads and programmable intelligent General Purpose IOs engine to control, through dedicated firmware, external actuators such as flashgun, white led and autofocus solution. STV0984 provides internal buffering capability along with a versatile clock manager to accommodate different data rates between input sensors and host interface.
