20 Reference Manual ReadyBoard 700
CPU (U4)
The ReadyBoard 700 offers three Intel processor choices; high performance 933MHz Low Voltage (LV)
Pentium® III processor, 650MHz Low Voltage (LV) Celeron® processor, or the low cost, 400MHz
Ultra Low Voltage (ULV) Celeron processor.
Celeron Processors
The Celeron processors (Tualatin core) at 650MHz or 400MHz have 256kB L2 Cache on board and use
a 100MHz FSB (front side bus). The Celeron processors require a heatsink, but no fan.
Pentium III Processor
The Pentium III processor (Tualatin core) at 933MHz has 512kB L2 Cache on board and uses a 133MHz
FSB. The Pentium III processor requires a heatsink, but no fan.
Memory
The ReadyBoard 700 memory consists of the following elements:
• SDRAM SODIMM
• Flash memory
SDRAM Memory (DIMM1)
The ReadyBoard 700 supports a single standard 144-pin SODIMM socket.
• SODIMM socket can support up to 512MB of memory
• Operating at 133MHz (7.5ns)
• +3.3V SDRAM
NOTE Ampro recommends using only PC 133 (133MHz), 3.3V, 7.5ns,
144-pin, SDRAM SODIMM, but PC 100 (100MHz, 10ns) will
function. PC 133 provides the best performance for the 933MHz
Pentium III and 650MHz Celeron processors.
Flash Memory
There is an 8-bit wide, 512kB flash device used for system BIOS that is connected to the Southbridge,
VT82C686B, through an ISA bus transceiver. The BIOS is re-programmable and the supported features
are detailed in Chapter 4, BIOS Setup.
