Description
Agilent Technologies and
Cypress Semiconductor have
once again collaborated efforts to
produce a new optical mouse
reference design kit. Based on
the new compact Agilent
ADNS-2620 optical mouse sensor
and the powerful Cypress
CY7C63723 enCoRe USB
microcontroller, this reference
design kit provides a low cost
and yet, feature-rich solution in
one neat package.
The Agilent ADNS-2620 optical
mouse sensor is a new small form
factor, entry-level sensor built
with performance features. This
part enables more compact
designs and performance
enhancements. Housed in an 8-pin
package, this sensor has program-
mable features such as frame
speeds (from 500 to 2300 fps),
automatic power conservation
when idle, and LED strobing for
lower power consumption,
enhancing navigation perfor-
mance. With an open serial
interface, it can communicate
with most common
microcontrollers.
The Cypress enCoRe CY7C63723
is a revolutionary chip that
integrates numerous common
components, including break-
through crystal-less oscillator.
The result is an overall reduction
in board components and re-
duced system cost. The EPROM
based microcontroller allows
easy firmware modification, as
well as storage of Vendor and
Product IDs without an exter-
nal EEPROM.
This kit is connectable to a PC
via the USB or PS/2 ports. A
single cable with a USB connec-
tor and a PS/2 adapter is also
provided. The design automati-
cally detects the type of interface
is attached, allowing further
development of a USB or PS/2
only mouse.
