High-Performance ARM920T Processor Core
The EP9301 features an advanced
ARM920T processor design with an MMU
that supports Linux, Windows CE and
many other embedded operating systems.
The ARM920T’s 32-bit microcontroller
architecture, with a five-stage pipeline,
delivers impressive performance at very
low power. The included 16 KB instruction
cache and 16 KB data cache provide
zero-cycle latency to the current program
and data, or can be locked to provide
guaranteed no-latency access to critical
instructions and data. For applications
with instruction memory size restrictions,
the ARM920T’s compressed Thumb
instruction set provides a space-efficient
design that maximizes external instruction
memory usage.
Integrated Five-Input,
Multiplexed A/D Controller
The EP9301 integrates a signed 12-bit
analog-to-digital converter with a
multiplexed front-end that is controlled
through a software-configured switch
matrix. This matrix allows routing of the
five input signals to the A/D sample
input or to the +REF and -REF inputs.
If external REF inputs are not required,
the A/D REF inputs can be internally
switched to VDD and GND allowing all
five inputs to be sampled. Reading a
sampled result enables a convert
command for the next sample. These
capabilities are especially useful in
process control and instrumentation
applications as well as voltage or
temperature monitoring.
MaverickKey Unique ID Secures Digital
Content and OEM Designs
MaverickKey unique hardware
programmed IDs provide an excellent
solution to the growing concern over
secure Web content and commerce. With
Internet security playing an important
role in the delivery of digital media
such as books or music, traditional
software methods are quickly becoming
unreliable. The MaverickKey unique IDs
provide OEMs with a method of utilizing
specific hardware IDs for DRM (Digital
Rights Management) mechanisms.
Both a specific 32-bit ID as well as a
128-bit random ID is programmed into
the EP9301 through the use of laser
probing technology. These IDs can then
be used to match secure copyrighted
content with the ID of the target device
that the EP9301 is powering, and then
deliver the copyrighted information
over a secure connection. In addition,
secure transactions can benefit by
matching device IDs to server IDs.
MaverickKey IDs can also be used by
OEMs and design houses to protect
against design piracy by presetting
ranges for unique IDs. For more
information on securing your design
using MaverickKey, please contact your
Cirrus Logic sales representative.
