Description

STA1275 and STA1295 are fully automotive, power efficient Systems-On-Chip, targeting

cost effective processing solution for modern Display Audio Systems.

They feature a powerful single or dual core Cortex? A7 processor (depending on the

versions), a high performance 3D GPU engine, a multi-format video decoder engine, a

multi-layer multi-format display controller, an audio DSP, a complete set of standard

connectivity interfaces and a dedicated ARM? Cortex? M3 controller for real-time CAN /

Vehicle Interface Processing.
