OVERVIEW
The CL-PS7500FE is a massively integrated general-purpose `system-on-a-chip' designed for a wide range of control and communications applications. Based on a low-power, high-speed ARM(R) RISC CPU core, the CL-PS7500FE integrates a powerful 50-MIPS processor, hardware floating point unit, memory interfaces, and a full complement of system peripherals onto a single chip. This integrated chip greatly simplifies system design for complex applications such as network computers, set-top boxes, screen phones, process control systems, and instrumentation control.

OVERVIEW (cont.)
In addition to the 32-bit processor with a hardware floating point unit, the CL-PS7500FE incorporates system cache, a MMU (memory management unit), a high-resolution color CRT/LCD graphics controller, a CD-quality audio controller, and various other peripheral interfaces. for separate memory blocks for display and program memory and reduces overall system costs. A dedicated high-speed DMA channel is used to control screen updates and minimize the overall system bandwidth devoted to display requirements.
I/O and Memory
In addition to the advanced peripherals incorporated into the CL-PS7500FE, a wide variety of Cirrus Logic and industry-standard third-party peripheral functions can be attached through the CL-PS7500FE's integrated 16-bit ISA-style I/O bus and eight general-purpose I/O signals. Peripherals such as modems, mass storage subsystems, CCD cameras, data acquisition subsystems, and bar code readers can easily be interfaced to the CL-PS7500FE through these connections. For example, the Cirrus Logic CS8900A Ethernet controller can be easily attached for high-speed network communications. The device also has direct connections for a PS/2-style keyboard and a mouse as well as a serial CD-quality stereo audio output.
Display Interface
The display controller section of the CL-PS7500FE features direct drive of an RGB color monitor or a color LCD. It supports up to a 120-MHz pixel clock rate for flicker-free screen refreshes at resolutions up to the XGA 1024 x 768. It also incorporates various sync signals; when combined with an external encoder device, these signals permit the use of interlaced television monitors for display. A hardware cursor is supported in all display modes to minimize system overhead during cursor updates. The CL-PS7500FE makes use of an UMA (unified memory architecture) that allows for a design to share system memory between the display function and the program memory. This eliminates the need

System-on-a-Chip with CRT/LCD Controller
For high performance, the built-in memory controller in the CL-PS7500FE supports EDO DRAMs. DRAMs can interface directly to the CL-PS7500FE in up to 4 separate banks for maximum design flexibility.
ARM (R) Compatibility
The ARM processor architecture is quickly becoming the industry's 32-bit standard. Investment protection in software and hardware designs is insured with over 30 companies building products based on this open, standard processor core. In addition, a wide range of realtime kernels, sophisticated operating systems, and state-of-the-art application development tools are available from third parties worldwide.
Speed Grades
The CL-PS7500FE is available in two speed grades:
q
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
System Design
As shown in the system block diagram below, simply adding desired memory and peripherals to the highly integrated CL-PS7500FE completes a highperformance system board. All the interface logic is integrated on-chip.
