The ARM920T microprocessor core with separate
16 kbyte, 64-way set-associative instruction and data
caches is augmented by the MaverickCrunch™ co-
processor enabling faster than real-time compression of
audio CDs.
The MaverickKey
are a 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 such as those assigned for SDMI (Secure
Digital Music Initiative) or any other authentication
mechanism.
A high-performance 1/10/100 Mbps Ethernet media
access controller (EMAC) is included along with external
interfaces to SPI, AC’97, and I
2.0 Full-speed Host (OHCI) (12 Mbits per second), two
UARTs, and a analog voltage measurement analog-to-
digital converter (ADC) are included as well.
The EP9302 is a high-performance, low-power RISC-
based, single-chip computer built around an ARM920T
microprocessor core with a maximum operating clock
rate of 200 MHz (184 MHz for industrial conditions). 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).
