(1)

The R5FSS cluster supports 512KB of Tightly-Coupled Memory (TCM). When configured as Single-Core or Lockstep operating mode,

individual cores can utilize the entire 512KB of TCM memory, while in Dual-Core mode, each core can only utilize its designated half

(256KB TCM).

(2)

AM261x supports 2 instances of the PRU Subsystem for a total of 4 real-time PRU cores.

(3)

Instead of one or more full instances of the SDFM peripheral, the ZNC package devices have 3 SDFM channels: SDFM0_D2,

SDFM1_D0, and SDFM1_D1.

(4)

ZNC packages devices have SPI0 and SPI2 as useable SPI interfaces.

(5)

Extended Automotive temperature is applicable to select part number variants as indicated by the Automotive Designator (Q1)

identifier in the Nomenclature Description table.

(6)

Extended Industrial temperature is applicable to select part number variants as indicated by the lack of the Automotive Designator (Q1)

identifier in the Nomenclature Description table.
