EZ-USB Series 2100
EZ-USB Series 2100 Xcelerator Development Kit
Development Board
The EZ-USB Xcelerator develop-
ment board is compact and
powerful. It provides an
AN2131QC, 64 kilobytes of
external RAM, two UARTS, and
user-programmable seven
segment display, LED indicators,
and switches. One UART is used
to communicate with the Win-
dows-hosted debugger, and the
other is free for application use.
The indicators and switches are
connected via the EZ-USB I
2
C
port, leaving all AN2131QC I/O
lines uncommitted for prototype
development. The board can be
USB bus powered, eliminating
the need for an external power
supply. A debug monitor loads
either into internal EZ-USB RAM
or the external RAM. The exter-
nal RAM can be configured in
various ways to allow seamless
code development for EZ-USB
ROM versions.
A matching plug-in breadboard
eases the interface of custom
circuitry to the AN2131. Headers
bring out all interface signals, and
provide a convenient interface to
a logic analyzer.
C Compiler from Keil
The C compiler from Keil Soft-
ware lets the designer write 8051
microcontroller applications in C
and still get the efficiency and
speed of assembly language.
Advanced features from Keil tools
include the ability to single step
through code. This makes it easy
to detect errors, handle source
level debugging and dual-data
pointer support, and set
breakpoints. With the ability to
debug code one line at a time,
quickly compile and one-step
download new code, developers’
have a more efficient means to
complete firmware faster than
using emulators.
The EZ-USB Xcelerator™
development kit provides a
complete hardware and
software solution for
accelerating the firmware
and device driver
development for all the
members of the EZ-USB
family. Other USB
development kits use
emulation of the eventual
USB device. The EZ-USB
Xcelerator developer kit uses
the actual device, the
AN2131QC, during the
entire development. Because
of the simplicity of EZ-USB
and Anchor’s software
utilities, users can be up and
running USB code in hours,
not weeks!
