System-on-a Chip for
Internet Appliance
OVERVIEW
The Cirrus Logic CL-PS7500FE is designed to be
used in internet appliances such as the network
computer, smart-TV, intranet terminal, screen
phones, DVD players, and so on.
The massively integrated CL-PS7500FE offers a
complete system-on-a-chip solution that includes a
32-bit ARM CPU with cache and MMU, CRT and
LCD controller, memory controller, FPU, CD-quality
sound controller, interface to the Cirrus Logic DSP
device for 56K modem and speakerphone, and a
PC-type I/O bus. To handle streaming of audio and
video data on the Internet, the CL-PS7500FE
includes a double-precision FPU to accelerate
software codecs.

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, FastPathmodem chipset ideal for Internet
access over a POTS line.
The CL-PS7500FE is available in two speed grades:
q ARM CPU running at 40 MHz; memory clock
running up to 64 MHz
q ARM CPU running at 56 MHz; memory clock
running up to 64 MHz
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.
