The RISC MPC505 MCU in cable set top converters

Abstract

Cable set top converters are taking on an increased computational role in the distribution of cable television signals. The MPC505 processor implements a very advanced controller that can deliver new levels of performance in a microcontroller chip. These new levels of performance are required in such applications as automotive engine control where there are many timing functions to be performed with very critical timing windows. The modularity of the device allows code written for a module on one processor to execute on any of the MPC500 family processors that contain the same module. The MPC500 instruction set is fully PowerPC/sup TM/ compliant. These features insure reusability of code and forward compatibility of code with future members of the MPC500 family. The ability to run at low voltages, processing speed and high levels of integration of the MPC505 along with the advantages of very high volume production combine to make this processor family a very powerful, economical MCU engine for embedded designs.
