Table A. Change History
The ARM920T microprocessor core has a separate 16-
kbyte, 64-way set-associative instruction and data
caches.
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 EP9301 is a high-performance, low-power RISC-
based, single-chip computer built around an ARM920T
microprocessor core with a maximum operating clock
rate of 166 MHz. 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 675 mW.
