Atmel offers new LIN series devices for automotive switch scanning applications and automotive ambient lighting control

Atmel® CorporaTIon, a leader in microcontrollers and touch technology solutions, announced the availability of new LIN series devices for automotive switch scanning applications and automotive ambient lighting control. The new devices ATA66415 and ATA664251 include other competitive solutions The solution can only achieve a wide range of on-chip functions by combining multiple devices.

The new LIN devices are available in ultra-small packages measuring only 5x5mm and 7x7mm, which significantly reduces the footprint of end applications and reduces the overall cost and development time of automotive ambient lighting applications.

Switch scanning applications for car doors, sunroof modules, and central stack can benefit from the device's extremely low sleep mode power consumption. The current source is controlled by three independent pulse width modulation (PWM) signals, suitable for controlling RGB LED environments Lighting solutions.

Overview: ATA664151 / ATA664251 LIN devices

The ATA664151 and ATA664251 LIN devices include an eight-channel high-voltage switch interface, current source, and analog voltage multiplexer to scan switches with currents up to 20mA in automotive applications. The integrated state change detector enables switch scanning applications with extremely low current consumption. The current source is controlled by three independent PWM signals, allowing the device to be used as an ambient lighting circuit to control RGB LEDs. LIN 2.2 and SAEJ2602-2 compatible transceivers are based on Atmel ’s third-generation LIN transceiver IP, have the best EMC immunity in the same class, and include a low-drop 5V voltage regulator with 80mA current capability and An adjustable window watchdog monitor.

ATA664251 is a system-in-package solution using the ATA664151 chip and Atmel AVR® 8-bit ATtiny167 microcontroller (MCU). The low-power RISC ATTIny167 MCU combines 16KB flash memory, 512B EEPROM, 512-Byte SRAM, and 16 general-purpose I / O line, 32 general working registers, an 8-bit and 16-bit timer / counter unit with compare mode, an 11-channel 10-bit analog-to-digital converter and three software-selectable energy-saving modes.

The above combination can develop simple, cheap but powerful nodes for ambient lighting and switch scanning applications.
