Atmel has introduced two new 8-bit AVR Flash microcontrollers with extended CAN (controller area network) capabilities. The devices combine 16 MIPS processing speed with a rich feature set and a superior in-application programming (IAP) capability.
They are ideal 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, claims the manufacturer.
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 or J1939) runs on the chip. A highly flexible IAP capability, via CAN, UART or SPI, allows remote programming and field upgrades.
Atmel offers a library of IAP routines as well as running Bootloader examples to customers wanting to build their own Bootloaders. 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 (2,7 V-5,5 V) plus five low-power management modes optimise the application power consumption.
A standalone development kit is available. AT90CAN32/64 samples are available in TQFP and QFN 64-pin packages in industrial temperature range.
