Longevity program: Texas Instruments General Quality Guidelines

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

20: PRODUCT WITHDRAWAL/DISCONTINUANCE

"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".

Available evaluation boards:

MayaEVB-Lite (available at 899,00 €)

MayaEVB-Lite is an adapter board designed to evaluate the functionalities of Maya system-on-module. Because the similarities between Maya system-on-module and NAON system-on-module, MayaEVB-Lite has been designed to allow for mating Maya on carrier boards originally designed for Naon. Thus MayaEVB-Lite shall always be used in combination with such a kind of carrier board (for example see NaonEVB-Lite and NaonEVB-Mid).
