Automotive chip supports 2D, 3D graphics up to 1080p

Article By : STMicroelectronics

The Accordo 5 line is capable of effects such as flexible blending of up to four layers with multiple modes and video overlay.

STMicroelectronics' new line of automotive processors, the Accordo 5, integrates complete graphics, video and audio functionality on-chip, allowing digital instrument clusters as well as audio-video-navigation (AVN) head units to become more affordable.

Among the features of Accordo 5 is smartphone mirroring, which gives access to content such as music and navigation services on the phone safely through the vehicle’s own user interface. The devices' 500MHz 3D graphics processor core supports 2D and 3D graphics up to 1080p resolution, in 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.

The Accordo 5 family is the latest generation of ST’s Accordo line, leveraging ARM Cortex-A7 processor as the main computing CPU. This microcontroller integrates three CAN ports including support for the latest CAN FD high-speed standard, a hardware accelerator for crypto algorithms including SHA-2, PK and AES, and One-Time-Programmable (OTP) memory for master-key storage and tamper prevention. 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.

Additional advances include increased thermal dissipation versus execution performance, which helps simplify thermal management, as well as flexible signal routing that simplifies audio design.

ST supports designers using the new chips with comprehensive software and middleware IP that streamlines the design of feature-rich displays and instruments.

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 19mm x 19mm x 1.7mm LFBGA529 package.
