The MPC5200 integrates a high performance MPC603e series G2_LE core with a rich set of peripheral functions focused on communications and systems integration. The G2_LE core design is based on the PowerPC core architecture. MPC5200 incorporates an innovative BestComm I/O subsystem, which isolates routine maintenance of peripheral functions from the embedded G2_LE core. The MPC5200 contains a SDRAM/DDR Memory Controller, a flexible External Bus Interface, PCI Controller, USB, ATA, Ethernet, six Programmable Serial Controllers (PSC), I2C, SPI, CAN, J1850, Timers, and GPIOs.
