(1) Developed for Functional Safety applications, the device supports hardware integrity up to ASIL-B. Refer to the related documentation for more details. Non-Functional Safety Variants are also available for AWRL6432 device.
(2) 3 Tx Simultaneous operation is supported only with 1V LDO bypass and PA LDO disable mode. In this mode, the 1V supply needs to be fed on the VOUT PA pin.
(3) As the certification can get secured at different times and post certificate the target will be updated to “compliant” from “compliance targeted” only in related data sheets, please refer to the respective data sheets for most recent compliance status.
(4) 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.
(5) 6 bits linear Phase Shifter.
(6) PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty.
