DM814x/AM387x – NAON

Processor:  Texas Instruments "DaVinci" DM814x / "Sitara" AM387x

NAON is the top-class Cortex-A8 CPU module by DAVE Embedded Systems, based on the recent Texas Instruments "DaVinci" DM814x / "Sitara" AM387x application processor.

NAON is a high-performance CPU module, designed to cover all requirements for a high range of applications where connectivity, rich user-interfaces and high computing capabilities are required, including industrial electronics, security systems, home automation and medical applications.

NAON offers great computational power, thanks to the rich set of coprocessors (NEON Media Technology, PowerVR SGX 530 3D accelerator, High Definition Video Coprocessing Engine, HD Video Processing Subsystem), keeping and extremely compact form factor (70mm x 50mm). Other standing out features are the C674x DSP (available on the DM814x processor), on-board NOR and NAND flash memories, support for high-resolution displays and industrial specification compliance (including the extended operating temperature range from -40 to +85°C).

NAON is designed in order to keep full compatibility with the ESATTA Line CPU modules (Lizard and Zefeer), to guarantee the economic and technical value of customers past investments, increasing at the same time performance, efficiency and software support.

Longevity program: Texas Instruments General Quality Guidelines

DAVE Embedded Systems is committed to support and maintain its products according to Texas Instruments General Quality Guidelines


"TI’s Product withdrawal/discontinuance process complies with JESD48, latest issue. TI makes an effort to not obsolete products out of convenience. Convenience means: low running device, poor yields, limited customer adoption or similar items. TI’s obsolescence withdrawal schedule provides a longer lead time than the industry standard. TI allows 12 months for the last order and an additional 6 months to take final delivery of obsolete items. In rare circumstances, an accelerated withdrawal schedule may be necessary. In such cases, TI will communicate the last buy and final delivery dates in the EOL notice, along with an explanation of the circumstances necessitating the early withdrawal".
