ATA663211 click
PID: MIKROE-2335
Weight: 35 g
ATA663211 click carries an Atmel LIN transceiver IC designed to handle low-speed
data communication in vehicles and in industrial applications with electrically harsh
environments. The LIN connection is established by attaching wires to the onboard
screw terminals.
The click communicates with the target MCU through the UART interface and runs on a 3.3V
power supply.
ATA663211 click can aslo be used as a standalone LIN transceiver, without being connected to a
mikroBUS™ socket. An onboard LDO (low-dropout regulator) enables it to get its power supply
through the VS line screw terminal.
LIN transceiver
LIN or Local Interconnect Network is a protocol used for communicating between components
in vehicles. These days cars have hundreds of sensor applications to measure things like
temperature, pressure, air flow, speed, etc. All these applications need to communicate with the
main system.
The LIN bus was created by European car manufactures in order to establish a new, uniform
communication standard. It can be used with CAN (Controller Area Network), but LIN is more
cost-effective for simple sensor networks in vehicles.
For more information see our Learn article on the LIN network protocol.
Low current consumption
The IC has three very low power modes: normal, sleep and fail-safe. In sleep mode the current
consumption is typically 9μA – this is the lowest current consumption mode. It automatically
switches to fail-safe mode at system power-up or after a wake-up event. In fail-safe mode it
typically uses 80μA.
Applications
Automotive industry and other electrically harsh environments.

What does a LIN transceiver do
LIN or Local Interconnect Network is a protocol used for communication between components
in vehicles. The car industry has changed profoundly during this century. Cars have hundreds of
sensor applications to measure things like temperature, pressure, air flow, speed, etc. All these
applications need to communicate with the main system. The LIN bus was created by European
car manufactures in order to establish a new, uniform communication standard. It can be used
with CAN (Controller Area Network), but LIN is more cost-effective for simple sensor networks
in vehicles.
But what is the difference between LIN and CAN network protocols? CAN is an a really
complex interface, and with so many electronic components in a car the manufactures needed a
cheaper alternative. The LIN interface is simpler than CAN — LIN uses a single wire
communication and the slave nodes are clocked by only one master. CAN interface has nodes
that can act independently, receive messages and act. It can have more than one master on the
CAN bus. A LIN network is usually made of up to 16 nodes - one master and 15 slaves. This
serial communications protocol is also well suited for other industrial applications with
electrically harsh environments.
Screw terminals
The click has three screw terminals: VS line for the power supply (up to 40V), GND for ground
and LIN line for connecting to the other transceiver LIN line.

Additional pins and jumpers
In addition to mikroBUS the click has four additional pins:
WKIN — high‐input voltage pin used to wake up the device from sleep mode.
EN — controls the operating mode of the device.
TXD and RXD — additional UART transmit and receive lines.
EN SEL jumper enables pin selection mode (by default it is always on, good for standalone purposes)
otherwise can be LOW ‐ then it is connected to EN pin on the mikroBUS.
Programming
Maximum baud rate which achieved with 2 meter long cable is 19200 bps. Supported compilers
C : ARM AVR FT90x PIC PIC32 The following code snippet shows a simple routine which
prints received data on a terminal. Any time a click board receives 8 bytes of data it will print
received data on another UART. In this case UART3 is used for ATA663211 and UART1 is
used to log data.
