NCV7321 fiche technique
NCV7321
Stand-alone LIN Transceiver
Description
The NCV7321 is a fully featured local interconnect network (LIN)
transceiver designed to interface between a LIN protocol controller
and the physical bus. The transceiver is implemented in I3T
technology enabling both high−voltage analog circuitry and digital
functionality to co−exist on the same chip.
The NCV7321 LIN device is a member of the in−vehicle
networking (IVN) transceiver family.
The LIN bus is designed to communicate low rate data from control
devices such as door locks, mirrors, car seats, and sunroofs at the
lowest possible cost. The bus is designed to eliminate as much wiring
as possible and is implemented using a single wire in each node. Each
node has a slave MCU−state machine that recognizes and translates
the instructions specific to that function. The main attraction of the
LIN bus is that all the functions are not time critical and usually relate
to passenger comfort.

Modes
Normal Mode: LIN Transceiver Enabled, Communication via the
LIN Bus is Possible, INH Switch is On
Sleep Mode: LIN Transceiver Disabled, the Consumption from
VBB is Minimized, INH Switch is Off
Standby Mode: Transition Mode reached either after Power−up or
after a Wake−up Event, INH Switch is on
Wake−up Bringing the Component from Sleep Mode into Standby
Mode is Possible either by LIN Command or a Digital Signal on
WAKE Pin (e.g. External Switch)
