Ambarella A12W 芯片spec

Product Brief

Overview

The Ambarella A12W Wearable Camera Processor is a

system-on-chip solution that integrates an advanced image

sensor pipeline (ISP), an H.264 encoder, and a powerful ARM®

Cortex™-A9 CPU for advanced analytics and user applications.

Targeting social and professional wearable camera designs,

the A12W is fabricated at the 28 nm manufacturing process
