Innovative Atmel AVR Microcontroller Solutions

for Automotive Applications

Increasing consumer demands for comfort, safety, and reduced fuel consumption are driving rapid growth in the

market for automotive electronics. All the new functions designed to meet these demands require local intelligence

and control, which can be optimized by the use of small, powerful microcontrollers.

Atmel leverages its unsurpassed experience in embedded flash memory microcontrollers to bring innovative solutions

for automotive applications. These include a wide range of AVR microcontrollers for everything from sensor or actuator

control to more sophisticated networking applications. Atmel microcontrollers are fully engineered to fulfill the quality

requirements of OEMs in their drive towards zero defects.

Atmel AVR Architecture Benefits:

8-/32-bit RISC Core: High Performance,

Low-power Consumption

The AVR 8- and 32-bit architectures have reached a

high level of acceptance in many market segments

because they provide:

and digital peripherals

a single clock cycle

optimization

Point Instructions (32-bit)

+150°C Qualified

up to +150°C ambient temperature (AEC-Q100

Grade 0). These devices enable designers to distribute

intelligence and control functions directly into or near

gearboxes, transfer cases, engine sensors actuators,

turbochargers and exhaust systems.

Automotive AVR solutions available in Grade 0 are the

Atmel ATtiny45, ATtiny87/167, ATtiny261/ 461/861,

ATmega88/168, ATmega16M1, ATmega32M1,

ATmega32C1, ATmega64M1, and ATmega64C1.

Automotive AVR microcontrollers are available in

two different temperature ranges to serve various

applications:

Carmakers are continuously adding comfort and safety

features to modern vehicles, resulting in the need for

more embedded computing power. As cost-effective

microcontrollers become available, carmakers now

have the ability to design distributed architectures with

scattered and reprogrammable 8-bit microcontrollers.

Alternatively, they can merge all functions into one

powerful 32-bit microcontroller with multiple peripherals

and networking connections.

Automotive: A Completely Distributed Architecture

AVR 8-bit microcontrollers are perfectly suited for distributed

architectures. They feature on-chip analog interfaces for

signal conditioning or programmable I/Os for actuator

signaling, and Controller Area Network (CAN), Local

Interconnect Network (LIN) or Pulse Wave Modulation

(PWM) networking connections to the Electronic Control

Unit (ECU).

Centralized architectures benefit from AVR 32-bit

microcontrollers with their rich peripheral sets and multiple

CAN and LIN connections.
