ADVANCE INFORMATION (AI),
or PRODUCTION DATA (PD)		PDPDPDPD
(1) Developed for Functional Safety applications, the device supports hardware integrity upto ASIL-B. Refer to the related documentation for more details.
(2) Device security features including Secure Boot and Customer Programmable Keys are available in select devices for only select part variants as indicated by the Device Type identifier in Section 3, Device Information table.
(3) The LVDS interface is not a production interface and is only used for debug.
(4) 3 Tx Simultaneous operation is supported only in AWR1843 with 1V LDO bypass and PA LDO disable mode. In this mode 1V supply needs to be fed on the VOUT PA pin. Rest of the other devices only support simultaneous operation of 2 Transmitters.
(5) PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
