2. JampII-mini Overview
JampII-mini a low cost compact sized single board computer based on Cirrus Logic EP9302
processor. With a large peripheral set targeted to a variety of applications, JampII-mini is well suited
for industrial controls, digital media servers, audio jukeboxes, thin clients, point-of-sale terminals,
biometric security systems, and GPS devices will benefit from the EP9302's integrated architecture
and advanced features.
2.1. Advanced Features
The heart of JampII-mini is the EP9302 which is the one in a series of ARM920T based
processors. The ARM920T microprocessor core with separate 16 Kbytes 64-way set-associative
instruction and data caches is augmented by the MaverickCrunch™ coprocessor. This enables faster
than real-time compression of audio CDs. The proprietary MaverickKey™ unique hardware
programmed IDs provide an excellent solution to the growing concern over secure Web content and
commerce. MaverickKey IDs can also be used by OEMs and design houses to protect against design
piracy by presetting ranges for unique IDs.
The EP9302 is a high-performance, low-power RISC-based device built around a single
ARM920T microprocessor core. The ARM920T on the EP9302 functions with a maximum operating
clock rate of 200MHz and a power usage between 100mW and 750mW (dependent upon clock
speed). The ARM core operates from a 1.8V supply while the I/O operates at 3.3V. The low power
consumption makes it an idea platform for battery operated applications.
A high performance 1/10/100 Mbps Ethernet Media Access Controller (EMAC) is included
along with external interfaces to SPI and I2S Audio. A two-port USB host and two UART are included
as well.
