3 HARDWARE COMPONENTS
The following picture shows where the main headers, connectors and most important
hardware components are located on the
TS-7250
. Understanding this picture will help
you to follow the header-connector oriented organization of this manual. The blue marked
objects on the picture are the on-board chips and components, while the red ones are the
various on-board headers and connectors for peripherals.

3.1 Processor
Cirrus EP9302
The EP9302 features an advanced 200 MHz ARM920T processor design with a memory
management unit (MMU) that allows support for high-level operating systems such as
Linux, Windows CE, and other embedded operating systems. The ARM core operates
from a 1.8 V supply, while the I/O operates at 3.3 V with power usage between 100 mW
and 750 mW (dependent on speed). As a general-purpose processor, it provides a
standard set of peripherals on board and a full set of Technologic Systems add-on
peripherals via the standard PC/104 Bus.
The ARM920T's 32-bit architecture, with a five-stage pipeline, consisting of fetch, decode,
execute, memory, and write stages, delivers very impressive performance at very low
power. The EP9302 CPU has a 16 KB instruction cache and a 16 KB data cache to
provide zero-cycle latency to the current program and data, or they can be locked to
guarantee no-latency access to critical sections of instructions and data. For applications
with instruction-memory size restrictions, the ARM920T’s compressed Thumb instruction
set can be used to provide higher code density and lower Flash storage requirements.
