1.1 Introduction
The EP93xx processors are highly integrated systems-on-a-chip that pave the way for a
multitude of next-generation consumer and industrial electronic products. Designers of digital
media servers and jukeboxes, telematic control systems, thin clients, set-top boxes, point-of-
sale terminals, industrial controls, biometric security systems, and GPS devices will benefit
from the EP93x processors’ integrated architecture and advanced features. In fact, with
amazingly agile performance provided by a 166 or 200 MHz ARM920T Core, and featuring
an incredibly wide breadth of peripheral interfaces, the EP93xx processors are well suited to
an even broader range of high volume applications. Furthermore, by enabling or disabling the
EP93xx processor’s peripherals and their interfaces, designers can throttle power
consumption and reduce development costs and accelerate time-to-market by creating a
single platform that can be easily modified to deliver a variety of differentiated end products.
1.2 EP93xx Features
Maximum clock rates plus package types and number of balls for EP93xx processors are
shown in Table 1-1.
Features of the EP93xx processors are summarized in Table 1-2. Block diagrams are shown
in Figure 1-1 EP9301, Figure 1-2 EP9302, Figure 1-3 EP9307, Figure 1-4 EP9312, and
Figure 1-5 EP9315.
