The MC9328MX21CVMR2 is a type of embedded microprocessor specifically designed for use in consumer products. It is an integrated system on a chip (SOC), with features such as MIPS32 4Kc processor core, floating-point unit (FPU), MMU and an exclusive cache memory management unit (MCM). This device is a part of the Freescale Microcontroller family, and is manufactured using the 0.18μm CMOS process. It is suitable for a variety of applications such as handheld multimedia devices, PDAs, information appliances, and industrial control systems.

The MC9328MX21CVMR2 is designed to provide robust, reliable performance and low power consumption. It has a system Bus Clock (BCLK) of up to 80 MHz, an Integrated Peripherals Module (IPM) that supports USB 2.0 and I2C, a Memory Management Unit (MMU), and 8 KB on-chip SRAM. In addition, it supports an extensive range of peripherals and memory, including common interfaces such as SPI, UART and SDIO.

The MC9328MX21CVMR2 integrates an ARM 9 core and uses a new, optimized microarchitecture. It offers several features including an MMU, fast interrupt response, native 4 byte instructions and improved instruction set. This processor has the unique ability to fit into a small footprint, making it suitable for embedded applications.

The MC9328MX21CVMR2 works based on the Von Neumann architecture, which consists of an instruction unit and a data processing unit connected by a common bus. This architecture is derived from the Harvard architecture, in which the instruction bus and data bus are separated. The Von Neumann architecture simplifies the operation of a system by eliminating the need for a separate data bus, allowing instructions and data to be retrieved from the same memory source.

The MC9328MX21CVMR2 also has an on-chip memory management unit (MMU). This unit is responsible for managing all of the on-chip resources and managing memory access. It provides memory protection, caching and paging and virtual memory support. The MMU works together with the peripheral subsystems to ensure that the processor has efficient access to all of the peripherals.

The MC9328MX21CVMR2 offers a number of advantages over other processors in the Freescale family, including a wide range of functions, low power consumption and extended operating temperature range. This device is also extremely cost-effective, making it an attractive option for a range of embedded applications. For example, it can be used in personal digital assistant (PDA) devices, mobile phones and embedded control systems.

In conclusion, the MC9328MX21CVMR2 is a highly versatile system on a chip (SOC) designed for use in embedded applications. It offers a wide range of functions, low power consumption and extended operating temperature range. It also features an on-chip MMU and supports peripherals such as USB and I2C. The MC9328MX21CVMR2 is a cost-effective solution for a variety of embedded applications and provides a high level of performance and reliability.
