Application Fields of MPC755CRX350TE

MPC755CRX350TE is a 32-bit, embedded microprocessor with real-time performance and capable of providing a wide range of solutions for embedded systems. This microprocessor is equipped with a PowerPC601 core and internal ROM or external ROM (up to 4Mbyte) as well as CMOS (Complementary of Metal Oxide Semiconductor) embedded memory technology, which enables a highly integrated system. Due to its powerful and flexible design, the MPC755CRX350TE is suitable for industrial controllers, communications, information technology, medical or automotive and other embedded systems. Also, due to its high performance and low power consumption, it can be applied to products such as portable and handheld devices. In addition, it has excellent real-time performance and interrupt latency. MPC755CRX350TE also features multiple peripherals, allowing for easy expansion.

Working Principle of MPC755CRX350TE

The MPC755CRX350TE is a high-performance microprocessor based on the PowerPC core. The processor consists of a 32-bit PowerPC core and a 128-bit CS10 bus. The bus is integrated into the processor from external memory access to the system control, including a high-performance AV-AMI or multi-master bus. In addition, there are also powerful 16-bit acceleration, 8/16/32-bit on-chip, embedded Flash, SDRAM and static RAM, PCMCIA controllers, interrupt controllers and other peripherals integrated in the same package. This package design greatly reduces the design and production costs of system hardware and ensures reduced power consumption and higher product reliability.

The internal architecture of the MPC755CRX350TE processor is composed of a high-speed 32-bit PowerPC RISC processor core and a 128-bit CS10 bus. Connected to the PowerPC processor core is an embedded memory controller, a 64-bit external interface, several DMA channels, 6 interval timer, 5 external interrupts, an enhanced I/O system controller, and a Battery Backed RAM controller. There are also on-chip 64-bit/128-bit encryption, 8/16/32-bit on-chip execution and non-volatile memory controllers.

The PowerPC 601 core consists of 32 32-bit general register files architecture, level 1 and level 2 caches, an internal test logic, an internal data and program access control logic, and two full-array ALUs, which include high-speed ALU and barrel shifter to support fast arithmetic and logic operation. An MMU is also included to support memory protection, provide virtual memory and segmentation of program and data instructions. In addition, the PowerPC 601 core also supports branch prediction and out-of-order completion.

The 128-bit CS10 bus provides high performance access to system memory and peripherals. The bus can support up to four external devices, each of which can transfer up to 16-bit data at a time, and has excellent performance in transferring data from external sources. In addition, the bus also includes a four-channel DMA controller, which can be used to transfer data from any of the four buses with minimal processor activity. This feature reduces the processing time for program execution, allowing for fast processing of I/O data and system control functions.

The MPC755CRX350TE processor also includes a variety of peripherals, such as a 10/100 Base-T Ethernet controller, a FIFO controller, a RTC (Real Time Clock), a voltage monitor, a watchdog timer, and a PMC (Power Management Controller). These powerful peripherals provide the MPC755CRX350TE processor with an excellent level of flexibility and scalability, allowing the processor to be used in a wide range of applications.

In conclusion, the MPC755CRX350TE microprocessor is a powerful and reliable embedded processor for industrial applications, due to its high-performance PowerPC core, integrated 128-bit CS10 bus, integrated peripheral controllers, and excellent real-time performance. In addition, it is also very suitable for mobile and embedded systems due to its low power consumption and rich peripherals.
