NT4N39AA CP Pentium IV Card
Figure 26: CP PIV card (side)

Functional description

The card employs an Intel Pentium Processor as the central processing unit. The internal core
clock frequency reaches from 600MHz to1.1GHz. The processor is manufactured in 0.09 um
process technology and provides 32 KB of on die data and instruction cache as well as 1 MB
of on die L2 cache running at core clock frequency. The processor is a mobile processor with
a 478 pin FCBGA package with a maximum junction temperature of 100 ûC. Processor power
dissipation must not exceed 12 W.
The front side bus runs at 400 MHz and uses an AGTL+ signaling technology. The quad
pumped data interface (data running at 4*100 MHz = 400 MHz) is 64 bit wide providing a total
bandwidth of 3.2 GBytes/s. The double pumped address bus (addresses running at 2*100 MHz
= 200 MHz) is 32 bit wide supporting an address range of up to 4 GBytes. The processor
voltage specification is compliant with IMVP IV specification.

Memory

CP PIV memory uses DDR SDRAM technology. The CP PIV provides a maximum of two
GBytes using two verticall DIMM sockets to install off-the-shelf DIMM modules. CP PIV only
supports DDR SDRAM DIMM memory with a supply voltage of +2.5 V.
