STMicroelectronics upgrades conventional camera module architecture

The new device also provides extra flash and torch brightness controls, with eight user-selectable levels for the flash and 12 for the torch, as well as a light-sensor input. Flash and torch safety timers, temperature sensing and short-circuit protection features are also built in.

The STCF04 is used in a unique configuration combining a supercapacitor, a discrete high-current MOSFET switch and high-power white LEDs, and is ideal for use in emergency high-intensity flashing lights as well as camera and cameraphone applications.

The discrete MOSFET is the key to the STCF04’s power advantage over other controllers that usually integrate a MOSFET of lower rating on the chip. Its extra power enables designers to provide the higher quantities of light energy required by today’s high-Mpixel camera sensors by specifying an LED flash unit rather than a conventional high-power xenon flash, thereby gaining the advantage of a compact and simplified design.

Since ST began sampling the STCF04, two major partners – Murata which is leading producer of supercapacitors (MURATA) and OSRAM which is a top-tier supplier of flash modules for leading smartphone platforms have begun using the device to showcase the best capabilities of their latest products.
