OVERVIEW
The CL-PS7500FE is a massively integrated gen-
eral-purpose 鈥榮ystem-on-a-chip鈥?designed for a wide
range of control and communications applications.
Based on a low-power, high-speed ARM
廬
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 appli-
cations such as network computers, set-top boxes,
screen phones, process control systems, and
instrumentation control.
