MPC823 : PowerQUICC" Integrated
Communications Processor for Portable
Systems
The MPC823 microprocessor is a versatile, one-chip integrated microprocessor and peripheral combination
that can be used in a variety of electronic products. It particularly excels in low-power, portable, image
capture and personal communication products. It has a universal serial bus (USB) interface and video
display controller, as well as the existing LCD controller of the MPC821 device.
The MPC823 microprocessor integrates a high-performance embedded MPC8xx core with a
communication processor module that uses a specialized RISC processor for imaging and communication.
The communication processor module can perform embedded signal processing functions for image
compression and decompression. It also supports seven serial channels--two serial communication
controllers, two serial management controllers, one I2C port, one USB channel, and one serial peripheral
interface.
This two-processor architecture consumes power more efficiently than traditional architectures because the
communication processor module frees the core from peripheral tasks like imaging and communication.
