The Motorola MC68302AG33C is an integrated data communications controller (IDCC) with a 16-bit processor core, peripheral function set, memory management, interrupt control, and a communications interface. It is ideal for designers who need to add communications capabilities to their systems without having to design in a separate microprocessor and communications sub-system. This IDCC is particularly suited for automotive applications, as it supports communications over multiple physical layers.

Application Field

The MC68302AG33C is commonly used in embedded systems, especially in automotive and industrial applications. It is suitable for applications such as in-vehicle network nodes, remote sensing, telematics systems, and other communication-related applications. It offers support for two CAN buses and two LIN buses, as well as an internal PULSE and CRT-T protocol. This makes it great for applications that require multiple simultaneous communications. It also offers an integrated Flash memory and a built-in I2C bus, making it ideal for applications that require high levels of integration.

Working Principle

The core of the MC68302AG33C is a 16-bit processor. The processor core has a reduced instruction set computer (RISC) architecture, making it power-efficient and easy to program. The processor also has an integrated data cache to reduce instruction fetch time and improve performance.

The MC68302AG33C has an integrated memory management system, which allows it to manage up to 4 MB of ROM or RAM. It also features an integrated interrupt controller, which allows the processor to respond to external interrupt events. The integrated communications functions are based on the Motorola MC9S08 family of serial communications controllers, which offer support for two CAN buses and two LIN buses, as well as an internal PULSE and CRT-T protocol.

The MC68302AG33C also offers on-chip debugging capabilities, which allows developers to quickly and easily debug their program during development. This can help reduce development time and cost.

Conclusion

The Motorola MC68302AG33C is an integrated data communications controller (IDCC) with a 16-bit processor core, peripheral function set, memory management, interrupt control, and a communications interface. It is suitable for applications such as in-vehiclenetwork nodes, remote sensing, telematics systems, and other communication-related applications. It offers support for two CAN buses and two LIN buses, as well as an internal PULSE and CRT-T protocol. As well as this, it also has an integrated Flash memory and a built-in I2C bus. These features make the Motorola MC68302AG33C an ideal choice for designers who need to add communications capabilities to their systems without having to design in a separate microprocessor and communications sub-system.
