The MPC5005 RISC microcontroller

The MPC505 microcontroller is the first implementation of a new family of microcontrollers that features a reduced instruction set (RISC) architecture based on the Power PC architecture. The internal architecture of the MPC505 implements a 32-bit structure. This architecture provides 32-bit effective addresses, integer data types of 8-, 16-, and 32-bits and floating point data types of 32 and 64 bits. A simplified block diagram of the MPC505 is shown in fig. 1. The MPC505 is designed to operate at 3.3 volts. Along with power conservation features, such as clock speed reduction, the MPC505 can operate on a relatively modest power budget
