The AT90CAN64-16MU microcontroller is a compact, low-power version designed to conform with the CAN bus communication protocol. The 16-bit RISC processor combined with the advanced peripherals make it suitable for a wide range of application fields. This article will focus on its application fields and working principle.

Application Fields

The AT90CAN64-16MU has a wide range of applications in the automotive industry. Its advanced features such as 8 channels of 8-bit time-base counters/timers and 4 communication interfaces allow the system to be used in automotive, aerospace and industrial applications. It is especially suitable for controlling real-time vehicular systems such as anti-lock braking systems, engine control systems, powertrain management systems and navigation systems.

Furthermore, its 4 channels of 8-bit parallel input/output ports and 4 channels of 8-bit digital-to-analog and-analog converters make it suitable for analog and digital sensor interface. This feature allows the MCU to be used in data-logging and measuring applications. For instance, it can be used to measure thermocouples and resistance thermometry in industrial and automotive applications.

In addition, the AT90CAN64-16MU can also be used in motor control applications. With its 4 channels of 8-bit 10-bit A/D converters integrated with timer-driven control and PWM output, the AT90CAN64-16MU is a great choice for applications related to brush- and brushless DC motors.

Working Principle

Essentially, the AT90CAN64-16MU microcontroller works by running programs written in high-level languages. It understands and interprets the instruction commands systematically as they are programmed. The 8-bit RISC architecture further supports the users by providing a faster, more reliable and more efficient performance.

The AT90CAN64-16MU has specific hardware designed to support communication protocol concepts, including the CAN protocol. The communication interface and 8-channel time-based counter offer a robust foundation for the execution and synchronization of data transmission in the bus system. The controller communicates with other nodes through the integrated CAN controller.

The application protocol is also made easier with the optional CAN protocol specific user modules, such as CANOpen, from Atmel. The user modules act as gateways, translating CANOpen messages into commands for the AT90CAN64-16MU. Additionally, the AT90CAN64-16MU provides support for the Local Interconnect Network (LIN) protocol, enabling the user to make fully featured designs.

The AT90CAN64-16MU also provides excellent flexibility for the development of user-defined applications. It allows for custom-defined communication protocols with the integrated support for the CANopen protocol. The user can also adapt the communication interface to support his specific needs using the integrated transceiver and the CAN controller.

Conclusion

The AT90CAN64-16MU microcontroller is a great choice for applications related to automotive, aerospace and industrial systems. Its wide range of features, including 4 channels of 8-bit 10-bit A/D converters integrated with timer-driven control and PWM output, 8-bit RISC architecture, 8-channel time-based counter, and the ability to support custom-defined communication protocols, make it the perfect solution for a wide range of applications. The integrated CAN protocol further enables the user to speed up communication and data exchange between nodes.
