The Accordo 5 family of automotive processors meet crucial display-performance and security demands in a low-power compact platform suitable for lower-cost vehicles. The devices enable state-of-the-art digital instrument clusters and Audio/Video/Navigation (AVN) head units to become more affordable than ever by integrating the complete graphics, video, and audio functionality on-chip to save design costs and simplify assembly.
The Accordo 5 family is the latest generation of ST’s successful Accordo line and leapfrogs other digital-infotainment chips, leveraging ARM® Cortex®-A7 processor as the main computing CPU. The Cortex-A7 architecture is highly area-efficient, and therefore cost-effective, with high processing and memory-streaming performance. The Accordo 5 range gives designers a choice of single-core Cortex A7 with a 16-bit interface to high-performing off-chip DDR3, or dual-core Cortex-A7 with a 16/32-bit DDR3 interface.
Although targeting mid-range vehicle markets, Accordo 5 delivers best-in-class graphics performance from its 500MHz 3D graphics processor core. The architecture supports 2D and 3D graphics up to 1080p resolution, in well-known formats like OpenVG, OpenGLES-2.0, and is capable of effects such as flexible blending of up to four layers with multiple modes and video overlay. The multi-format video subsystem provides post-processing for effects such as picture-in-picture, and virtuoso audio performance comes from a high-performance audio DSP, six stereo-audio analog channels, and support for multiple industry-standard audio interfaces. The built-in display controller supports TFT-LCD touch panels up to Full HD definition.
Additional advances include increased thermal dissipation versus execution performance, which helps simplify thermal management for optimum reliability, as well as flexible signal routing that simplifies audio design.
The Accordo 5 family comprising the STA1275, STA1285, and STA1295 is in sampling phase now. The STA1295 with dual-core Cortex-A7 processor is available in a 19 mm x 19 mm x 1.7 mm LFBGA529 package.
