WT8932NF

【 General Description 】

The WT8932NF is a high performance image processor which incorporates a 32-bit RISC CPU with DSP instruction set that operates up to 180 MHz and optimized for image sensors with HiSPi/MIPI interfaces. In addition, the WT8932NF embeds a hardware image processor unit (IPU) and supports input resolution up to 8 megapixels, providing real-time and superior visibility technology for camera applications.

The WT8932NF requires few external components and can be easily integrated into a camera module. It thus simplifies the system hardware design easily and shortens the time to market of the end product.
