Atmel Automotive Solutions
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.
+150°C Qualified
Atmel AVR
®
microcontrollers are qualified for operation
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:
•
AEC-Q100 Grade1 Z: -40°C to +125°C
•
AEC-Q100 Grade 0 D, T2: -40°C to +150°C
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:
•
Highest system integration with a large number of analog
and digital peripherals
•
Highest CPU performance with executing instructions in
a single clock cycle
•
Highest code density with high-level C-language
optimization
•
Dedicated Digital Signal Processor (DSP) and Floating
Point Instructions (32-bit)
•
Self-programming memory
•
Product compatibility for both code and features
•
Complete and low-cost tool set
•
Brown-out detection and flash corruption security
Automotive: A Completely Distributed Architecture
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.
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.
