Atmel Extends Its AVR CAN Microcontroller Family for Industrial CAN Applications

Nantes, France (ots/PRNewswire)

- New Devices Offer a Highly Flexible In-Application Programming
with Extended CAN Capabilities
Atmel(R) Corporation (Nasdaq: ATML), a global leader in the
development and fabrication of advanced semiconductor solutions,
announced today the introduction of the AT90CAN32 and the AT90CAN64,
8-bit AVR(R) Flash microcontrollers with extended CAN (Controller
Area Network) capabilities. These new devices combine 16 MIPS
processing speed with a rich feature set and an unmatched
In-Application Programming (IAP) capability. They are perfectly
suited for many CAN networking and industrial applications, including
lifts, escalators, door modules in transportation and factory
automation (I/Os, sensors and battery chargers).
Pin-to-pin compatible with Atmel's 128-Kbyte AVR CAN
microcontroller (AT90CAN128), the AT90CAN32/64 devices integrate in a
single chip, a V2.0A/V2.0B CAN controller, a 32-/64-Kbyte Flash
program memory, a 2-/4-Kbyte RAM, and a 1- /2-Kbyte on-chip EEPROM.
With a 16 MIPS AVR RISC-engine, the AT90CAN32/64 devices offer
designers a performance equivalent to a 16-bit microcontroller at the
price of a standard 8-bit device for their Industrial Control
applications.
The on-chip CAN controller can handle 15 independent message
objects, programmable on-the-fly, and dynamically assign them to the
reception, transmission or reception buffers in case of multiple CAN
frames. Extensive masking, filtering and buffering of CAN frames
reduces the host processor load. A large portion of the AT90CAN32/64
processing speed and memory remains available for the application
while a complete higher layer protocol stack (CANopen, DeviceNet(TM)
or J1939) runs on the chip. An interrupt accelerator engine informs
the CPU of critical messages without running a software scan routine,
minimizing the overhead impact on real time event applications.
A highly flexible IAP capability, via CAN, UART or SPI, allows
remote programming and field upgrades. Atmel's IAP allows to simply
reprogram any CAN node through the CAN bus, without disturbing the
CAN bus exchanges, or interrupting the running system. In comparison,
the so-called IAP capabilities available on the market require a
manual operation to stop the system, to shift the system to the
programming mode and to re-start it. Atmel offers a library of IAP
routines as well as running Bootloader examples to customers wanting
to build their own Bootloaders, thereby reducing overall development
time and thus time-to-market.
AT90CAN32/64 peripherals include 16-bit timers with enhanced Pulse
Width Modulation capabilities, a powerful 10-bit/8-channel A/D
converter and several serial interfaces. A wide operating voltage
range (2.7V-5.5V) plus five low-power management modes optimize the
application power consumption.
Manish Vadher, Atmel's marketing director said, "After a
successful introduction of the AT90CAN128 AVR CAN microcontroller,
Atmel is now  expanding the AVR CAN family. The AT90CAN32/64 are
highly cost-effective  solutions and fully compatible with the larger
AT90CAN128. These new AVRs  with a CAN controller offer an unrivalled
feature set and confirm our  commitment to the CAN networking
market."
The stand-alone development kit, ATDVK90CAN1, is available for
US$115. This allows the user to start a development and then easily
port the software onto an application. It can be used to evaluate the
performance as well as to demonstrate CAN features. With the kit,
Atmel also provides a C-code driver library for all peripherals
including the CAN-driver and various program examples.
Atmel's AT90CAN128 starter kits, which include the ATSTK500/501
and the ATADAPCAN01 also offer an easy way to get started with the
new AT90CAN32/64 devices.
AT90CAN32/64 samples are available now in TQFP and QFN 64-pin
packages in industrial temperature range. AT90CAN32 production
volumes are expected in December 2005, and in March 2006 for the
AT90CAN64. Pricing for 10,000 units is US$4.50 per unit for the
AT90CAN32, and will be US$5 for the AT90CAN64.
