(2) Device security features including Secure Boot and Customer Programmable Keys are applicable to select part number variants as indicated by the Device Type (Y) identifier in the Table 10-1, Nomenclature Description table (3) AEC-Q100 qualification is applicable to select part number variants as indicated by the Automotive Designator (Q1) identifier in the Table 10-1, Nomenclature Description table (4) USB3.0 and PCIE share a total of four SerDes lanes. (5) Two simultaneous flash interfaces configured as OSPI0 and OSPI1, or HyperBus and OSPI1. (6) J721S2 is the base part number for the superset device. Software should constrain the features used to match the intended production device. (7) OSPI1 module only pins out 4 pins and is referred to as QSPI in some contexts. (8) Hyperlink is not supported on this SoC. System designs should not use the signals HYP_*, HYP0_*, HYP1_*. (9) MCU_R5FSS0 includes Dual-Core R5F that provides Device Management functionality, and is reserved for executing TI provided code. R5FSS1 is a Dual-Core R5F that provides Multimedia Control functionality, and is reserved for executing TI provided code. (10) The two C7x DSPs are reserved for executing TI provided code, and are not available for custom code. www.ti.com AM68A SPRSP91 – FEBRUARY 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 7 Product Folder Links: AM68A |
