User’s Manual PowerPC 750CL Tsi109 Evaluation Board 2.1 Processor 2.1.1 60X Bus The 750CL 60x bus connects seamlessly to the Tsi109. The processor bus interface is set at 1.8V. The following 60x bus signals are not supported by the Tsi109 and are pulled appropriately: Table 2-1.
The Tsi109 has several power-up options; some are system specific while others are application specific (for more information, see the Tsi109 User Manual). The PowerPC 750CL Tsi109 Evaluation Board sets the power-up options with either jumper blocks or soldered down pull-up/pull-down resistors. The list of available power-up options is provided in Section 8 on page 45.
User’s Manual PowerPC 750CL Tsi109 Evaluation Board 2.4 DDR2 DIMM (Memory Module) Connectors The board incorporates two 240-pin DIMM connectors and the appropriate termination circuit. The following memory configurations are supported: • 1 or 2 registered DIMM at DDR2-400 speed •...

User’s Manual PowerPC 750CL Tsi109 Evaluation Board Three PCI/X slots are available on the board. The slot closest to the Tsi109 is designed to meet 133MHz PCI-X timing. The first slot is isolated from the other slots by a FET bus switch. The FET switch reduces the load and the stub length seen from the Tsi109.
User’s Manual PowerPC 750CL Tsi109 Evaluation Board 2.9 SEEP and Real Time Clock One Serial EEPROM (SEEP) is connected on the Tsi109 I C chain. The device (24LC16) from Microchip is used to store configuration information for the Tsi109. The SEEP is accessed during power up. If it is blank, the Tsi109 uses its default configuration settings.
User’s Manual PowerPC 750CL Tsi109 Evaluation Board 2.10.1 Power Rating Per Rail The power requirement is calculated from “worst case” figures from component datasheets; the real figures are lower. DDR2 power is based on 512M registered modules. 2000mA/rank is an average between Operating Burst Write current and Burst Refresh Current.
