MPC850DEZQ50BU

The MPC850DEZQ50BU or PowerPC850 is an embedded microprocessor based on the PowerPC architecture. It was first released in 1994 and is still in production today. The processor is usually used in communications systems and embedded controllers, but can also be used in other applications. It is typically used in industrial automation and control, consumer electronics, avionics, military, and telecommunications.

The PowerPC850 has a 32-bit integer pipeline and a 32-bit floating point pipeline. It can also support up to 128 MB of external RAM and has a clock speed of up to 25 MHz. The processor also supports two UARTs, four serial ports, one parallel port, and two timers. It also includes an on-chip Ethernet controller and a 32-bit coprocessor interface.

The PowerPC850 is a highly integrated microcontroller that includes the CPU core, memory management unit, direct memory access controller, interrupts, and other peripherals. The CPU core is based on the PowerISA architecture and includes a maximum of 57 instructions. It also supports up to eight data addressing modes and has a three-stage instruction pipeline.

The processor also features an advanced memory management unit (MMU). This unit controls the access to memory by the CPU, including segmentation and paging. It also provides support for virtual memory and addresses with both physical and virtual addresses.

The direct memory access (DMA) controller is mainly used to transfer data between memory and other peripherals. It can be used to transfer data between different types of memory, between I/O devices, and between the CPU and I/O devices.

The processor also includes several interrupt controllers. These are mainly used to manage the priorities of different interrupt sources. It can handle up to 16 external interrupt sources and has up to three priority levels for interrupt handling.

The PowerPC850 also includes a 32-bit coprocessor interface. This interface allows a coprocessor to access data and instructions in order to accelerate certain tasks. The coprocessor can be used for various tasks such as digital signal processing, graphics processing, encryption, and other types of processing.
