Automotive: A Completely Distributed
Architecture
Comfort and safety features are continuously being
added to modern vehicles, requiring more embedded
computing power. As cost-effective microcontrollers
become available, car makers now have the ability
to design distributed architectures with scattered
and reprogrammable 8-bit controllers. Alternatively,
they can merge all functions in one powerful 32bit microcontroller with multiple peripherals and
networking connections. The Atmel 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 CAN, LIN or PWM networking
connections to the ECU.
Centralized architectures benefit from 32-bit AVR
microcontrollers with rich peripheral set and multiple
CAN and LIN connections.
CAN Microcontrollers
Two families of automotive 8-bit AVR microcontrollers
include an ISO 16845 certified CAN controller
peripheral: Atmel AT90CAN128/64/32 series,
Atmel ATmega64 M1/32M1/16M1 and Atmel
ATmega64C1/32C1 series. They also feature a
self-programming technology and a comprehensive
set of analog and digital peripherals. With 16Kbytes
to 128Kbytes of Flash, they cover a large range of
applications. Vector Informatik drivers are available for
the 8-bit AVR microcontrollers.
The first 32-bit AVR family UC3Cx512/256/128
incorporates an ISO 16845 certified dual CAN
controller with 128 to 512Kbytes of Flash. The 32-bit
AVR products are supported by a complete OSEK
OSCAN driver and CAN boot loader.
The Atmel ATtiny167/87 family with a hardware LIN
featuring self-synchronization serves cost-sensitive
LIN slave applications. The same hardware LIN is
also available in Atmel dedicated motor-control AVR
products—the Atmel ATmega64M1/32M1/16M1 and
Atmel ATmega64C1/32C1. A hardware LIN reduces
the flash memory footprint and minimizes LIN real-time
constraints.
LIN2.1 protocol stacks are available from Mentor
Graphics, Vector Informatik and Dunasys for all AVR
microcontrollers with general-purpose USART or
hardware LIN.
LIN Bus Transceivers
The modular Atmel LIN transceiver family includes
simple transceiver ICs (Atmel ATA6662C/63/64/70)
and complex system basis chips (Atmel ATA6622C/
23C/24C/25C/26C/28/29/30/31). All Atmel LIN
transceivers are compliant with the LIN specification
2.1 and the SAE J2602-2. A combination of voltage
regulator and bus transceiver enables the development
of simple, yet powerful slave nodes for LIN bus systems.
The ATA6622C/24C/26C/28/30 transceivers also
include a window watchdog. The Atmel ATA6626C/64
transceivers, which do not include a time-out feature
at the LIN bus, are perfect for systems requiring very
slow LIN communication. These devices are designed
in the Atmel SMART-I.S.® high-voltage BCD-on-SOI
process. Due to the advantages of silicon on insulator
(SOI) technology, this generation sets new benchmarks
for EMI performance. Its ESD protection (8kV) is best
in class and enables the design of robust electronic
units for harsh automotive environments. This includes
automotive comfort applications, intelligent sensors, or
other body electronic applications where low-speed
data communication and low costs are a requirement.
LIN Microcontrollers
All automotive Atmel ATmega products feature a
general-purpose USART to support LIN master and
slave systems. A calibrated RC oscillator satisfies
the LIN slave synchronization requirements. For LIN
master applications, an oscillator with external crystal
or resonator is also available.

Atmel AVR Microcontrollers for Automotive
The highest integration level is achieved by Atmel
ATA6612C/13C/14Q/16C/17C system-in-package
(SiP) solutions. With these devices, the die of the
the ATA6624C or ATA6630 LIN system basis chip
(SBC)—including LIN transceiver, voltage regulator,
and watchdog—is assembled together with an
AVR microcontroller (Atmel ATmega88/168 and
Atmel ATtiny87/167) in a single QFN package.
Consequently, these SiP solutions enable customers
to create complete LIN nodes using just one IC. As
all pins of the AVR and SBC are bonded out, the full
range of AVR tools are available for development.
The ATA664251 is a system-in-package solution
with an ATA664151 chip and an Atmel AVR 8-bit
ATtiny167 microcontroller.

Battery Management
The AVR® ATmega32HVE2 and ATmega64HVE2
microcontroller-based devices with smart sensing
technology are designed for intelligent battery
sensor applications. The system-in-package solutions
determine the state-of-charge and state-of-health
of 12V standard lead-acid and lithium-ion batteries
by measuring the battery voltage, current and
temperature with up to 18-bit accuracy. This
improves the performance and longevity of these
batteries, and ensures a guaranteed engine start for
cars with idle-stop-go function.
Switch Scan and Ambient Lighting
Atmel’s ATA664151 and ATA664251 for automotive
switch scan applications and in-vehicle ambient
lighting control include a broad range of on-chip
functionalities.
The 8-channel high-voltage switch interface with
current sources and analog voltage multiplexer
enables to scan automotive switches with currents
up to 20mA. An integrated state change detector
facilitates switch scan applications with extremely
low current consumption. The current sources
are controlled by three independent PWM signals
enabling the device to act as an ambient light circuit to
control RGB LEDs.
Atmel AVR Microcontrollers for Automotive
Motor Control Applications
Brushless DC motors (BLDC) are increasingly
being employed in power train, chassis and body
applications. Atmel has developed two families of 8-bit
microcontrollers supporting Hall sensor and sensorless
applications.
The first of these families is the Atmel
ATmega64M1/32M1/16M1, which includes not
only a powerful set of analog and digital peripherals
optimized for up to six phases BLDC but also CAN and
LIN communication to the ECU.
The second family is the Atmel ATtiny861/461/261,
which includes a powerful set of analog and digital
peripherals for BLDC. This family supports costsensitive applications where communication with the
ECU is carried out via a simplified I/O system such as
PWM command/response.
A family of high-voltage drivers complements Atmel
motor-control solutions.

Quality: Atmel Fully Committed to
Automotive
Dedicated Resources for Dedicated
Methodologies
AVR microcontrollers meet the most stringent
requirements for ensuring robust functionality in
harsh environmental conditions. This is the result of
more than 25 years experience in automotive design
coupled with a continuous quest for excellence
throughout the entire organization. The Atmel Quality
Management System has complied from its inception
with the highest-level standards, including ISO/TS
16949. As a result, car makers worldwide have for
many years employed Atmel microcontrollers in
a variety of vehicle applications—from infotainment to
safety-critical functions, as well as multiplexing. This
industrial expertise plus extended R&D efforts have
allowed Atmel to successfully address the market of
“Grade0” microcontrollers capable of withstanding
the most severe environmental conditions.
In the quality domain, as in many others, Atmel is
a leader in its field. Beyond a full product qualification
according to AEC-Q100, Atmel has embedded quality
into the entire product lifecycle—from the early design
stage until the end of life. This includes the application
of particular techniques, tools and methodologies
such as identification of Special Characteristics, Failure
Modes and Effects Analysis (FMEA), design-for-test
techniques, Part Average Testing (PAT) or Advanced
Burn-In (AdBI), optimized capability, safe launch
support teams and more. These approaches are
developed and deployed by a dedicated automotive
structure that includes world-class Marketing, Design,
Applications, Product Engineering and Quality and
Reliability in-situ facilities.

Atmel AVR Microcontrollers for Automotive
Key Atmel Quality Objectives for
Automotive Success
• Zero defects is our goal, zero tolerance is our approach
• 100% on-time delivery
• Excellence in development and manufacturing to exceed customer expectations
• Immediate response to minimize the impact of any customer issue
• Total commitment by all employees throughout the entire organization
Atmel AVR Microcontrollers for Automotive
Continuous Improvement
To meet the zero-defect challenge, Atmel launched
a three year automotive quality plan in 2008 that
resulted in harmonized targets, development, and
supply chain and quality policy for the automotive
portfolio. The implementation of a customer-focused
quality structure has further enabled the company
to closely adhere to customer-specific requirements.
Atmel is also continuously examining its development
and qualification approaches to achieve best-in-class
reliability. All this explains why Atmel plays a key role
in several major automotive European programs—
such as Failure-driven Qualification (Medea+ A407
FdQ) and End of Life Investigation for Automotive
Systems (Catrene 2T204 ELIAS)—which are paving
the way to future international standards. These
important R&D programs have resulted in techniques
for Robustness Validation (SAE J1879) and contribute
to support the new requirements of Road Vehicles
Functional Safety (ISO 26262).
