ATA663211 click

Description of product

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.
