2 Electrical Circuit Explanation
2.1.
SC PC Board (System Control Printed Circuit Board)
1. System CPU
The System CPU (PPC405EP) is a 32-bit RISC (Reduced Instruction Set Computer) type of CPU and
EBC Control (ROM/SRAM), PC133 SDRAM Control, PCI Control, DMA Control, Serial Communication
Port, Timer, Interrupt Control, Ethernet MAC and IIC Control are integrated into 1 chip.
The EBC is connected to the Power-on Boot space. The 405 processor will begin with an initial fetch to
address 0xFFFFFFFC. The EBC is setup to respond to this Boot address and the request will go to
bank 0. This bank must have a ROM attached with the Boot code to begin the processor execution.
