Chapter 3 Hardware

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.
