NCV7327 LIN Transceiver, Stand-alone Description The NCV7327 is a fully featured local interconnect network (LIN) transceiver designed to interface between a LIN protocol controller www.onsemi.com and the physical bus. 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 MARKING DIAGRAMS as possible and is implemented using a single wire in each node. Each node has a slave MCUstate machine that recognizes and translates 8 the instructions specific to that function. SOIC8 NV73270 8 The main attraction of the LIN bus is that all the functions are not CASE 751AZ ALYW 1 time critical and usually relate to passenger comfort. 1 Features 1 LINBus Transceiver NV73 DFNW8 Compliant to ISO 179874 (Backwards Compatible to LIN 270 CASE 507AB ALYW Specification rev. 2.x, 1.3) and SAE J2602 1 Bus Voltage 42 V Transmission Rate up to 20 kbps (No low limit due to absence of A = Assembly Location TxD Timeout function) L = Wafer Lot Y = Year Integrated Slope Control W = Work Week Protection = PbFree Package Thermal Shutdown (Note: Microdot may be in either location) Undervoltage Protection Bus Pins Protected Against Transients in an Automotive PIN CONNECTIONS Environment 1 8 Modes RxD NC 2 7 Normal Mode: LIN Transceiver Enabled, Communication via the EN V BB 3 6 Bus is Possible NC LIN Sleep Mode: LIN Transceiver Disabled, the Consumption from 4 5 TxD GND V is Minimized BB SOIC8 (Top View) Standby Mode: Transition Mode Reached after Wakeup Event on the LIN Bus RxD 1 8 NC Compatibility V PinCompatible Subset with NCV7321 EN 2 7 BB EP Kline Compatible NC 3 6 LIN NCV7327 differs from NCV7329 only by absence of TxD TxD 4 5 GND Timeout function DFNW8 (Top View) Quality Wettable Flank Package for Enhanced Optical Inspection ORDERING INFORMATION AECQ100 Qualified and PPAP Capable See detailed ordering and shipping information on page 10 of These Devices are PbFree, Halogen Free/BFR Free and are RoHS this data sheet.
