EP9307 Datasheet, PDF (2/48 Pages) Cirrus Logic – ARM9 SOC WITH ETHERNET USB DISPLAY AND TOUCHSCREEN

EP9307
ARM9 SOC with Ethernet, USB, Display and Touchscreen
OVERVIEW
The EP9307 is an ARM920T-based system-on-a-chip
(SOC) design with a large peripheral set targeted to a
variety of applications:
• Thin client computers for business and home
• Internet radio
• Internet access devices
• Industrial computers
• Specialized terminals
• Point of sale terminals
• Test and measurement equipment
The EP9307 is one of a series of ARM920T-based
devices.
The ARM920T microprocessor core with separate
16 Kbyte, 64-way set-associative instruction and data
caches is augmented by the MaverickCrunch™ co-
processor enabling high-speed floating point
calculations.
MaverickKey^™ unique hardware programmed IDs 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 (MAC) is included along with external
interfaces to SPI, I²S audio, Raster/LCD, 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 EP9307 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).
