PowerPro delivers memory control support for PowerPC processors (MPC750, MPC740, MPC85xx) and the Tundra PowerPC-to-PCI bus switch - PowerSpan. The Tundra PowerPro is designed for applications to leverage the Switched PCI architecture of PowerSpan in PowerPC applications.
In MPC750/MPC8260 designs, the PowerPro enables ECC protection, which is not otherwise available from the MPC8260 in this application.
Key features include PC-100 SDRAM control and ECC protection: these features are becoming standard requirements in next generation PowerPC systems. PowerPro supports 8-bit,16-bit, and 32-bit Flash, as well as other local peripheral devices such as UARTs.
Commercially available PowerPC memory controllers are traditionally combined with a large and complex PCI host bridge.PowerPro is the only discrete SDRAM controller on the market today for non-PCI PowerPC applications.
