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.
Applications
Mobile phone
PDA
Wireless security camera
