OVERVIEW (cont.)

The video controller features RGB drive of a SVGA

monitor or a color LCD. It also incorporates various

sync inputs, which when combined with an external

encoder, permit the use of interlaced TV displays.

The device incorporates a digital audio controller

with a 32-bit serial interface for connection to the

Cirrus Logic, CS4333 CD-DAC device. The

CL-PS7500FE can also interface to the Cirrus Logic

56K, FastPath modem chipset ideal for Internet

access over a POTS line.

The CL-PS7500FE supports UMA (uniﬁed memory

architecture); EDO DRAMs can be used to achieve

high-memory bandwidth.

The CL-PS7500FE is the main computing engine in

the NC platform deﬁned by Oracle , and runs the

NC operating system and applications.

The device is available in a 240-pin PQFP (plastic

quad ﬂat pack) package.

The CL-PS7500FE is available in two speed grades:

●

ARM CPU running at 40 MHz; memory clock

running up to 64 MHz

ARM CPU running at 56 MHz; memory clock

running up to 64 MHz
