Application Field

The MC9328MXSCVP10R2 is designed for embedded applications. Its features make it suitable for applications such as smart meters, HVAC systems, motor control, automotive, automotive body control, and various other industrial automation systems. The processor is especially suited for applications that have limited memory and power requirements.

Features

The MC9328MXSCVP10R2 is an 8-bit microprocessor that comes with a 64-KB ROM, 16-KB RAM and 32+4-KB ROM. The processor also has 168 interrupt sources, four external interrupts, and 10 internal interrupts. It is a dual-phase clock unit and operates from 2.7V to 5.5V, with a maximum operating frequency of 54MHz.

Architecture

The MC9328MXSCVP10R2 is an 8-bit microprocessor that uses an advanced CPU design architecture. It is based on the MC9328MXSCPU core, which is a highly optimized processor designed to provide fast system performance while consuming minimal power. The processor features a 64-entry vector table, 60 vector interrupt sources, four external interrupts, and 10 internal interrupts. It also supports up to five CPU interrupt control registers, which enable the processor to handle multiple interrupt requests at the same time. In addition, the processor supports four slave address bus lines, 16-bit instruction and data bus, and 8-bit peripheral bus.

Peripheral Support

The MC9328MXSCVP10R2 supports a range of peripherals and interfaces ranging from UART, SPI, I2C, and USB, to Ethernet, CAN and LIN networks. It also offers six DMA channels and an integrated 10-bit A/D converter for analog input capabilities. The peripheral support includes support for two UARTs and two SPI ports, one USB and one I2C, three timer/counters, and two PWM outputs.

Working Principle

The MC9328MXSCVP10R2 operates by fetching instructions from memory and executing them. The processor fetches instructions from memory, decode them, and executes the instructions one by one. The processor can also access data from other sources, such as from RAM or from external peripherals, as required. Once an instruction or data is fetched, the processor executes it and stores any data results in RAM for future use. The processor can also transfer data or instructions to and from peripheral hardware such as memory, I/O devices, and other processes.

Conclusion

The MC9328MXSCVP10R2 is a powerful 8-bit microprocessor from Freescale Semiconductor. It is designed for use in embedded applications and features a 64-KB ROM, 16-KB RAM and 32+4-KB ROM, as well as varied peripheral support. The processor operates by fetching instructions from memory and executing them as needed. This allows the processor to quickly access data from RAM or from external peripherals, as well as to transfer data or instructions to and from other processes. It is suitable for applications that have limited memory and power requirements.
