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, I
peripherals, keypad, and touchscreen. A three-port USB
2.0 Full Speed Host (OHCI) (12 Mbits per second) and
three UARTs are included as well.
The EP9315 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).
