Select a block to see what it receives and feeds; the arrows show each connection.

Scope, as the sheet states it: 130 nm at 200 MHz owns the zonal layer: gateway, smart I/O, safety and security edge. Central software-defined-vehicle compute is a sub-10 nm part and is not claimed here.

  1. ① Messages arrive on Ethernet, CAN and LIN.
  2. ② The TSN switch schedules them against precision time.
  3. ③ The service router forwards them across the crossbar.
  4. ④ They become switched power at the smart fuses.
  5. ⑤ A lockstep mismatch drives the safe state.
