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 programmable features such as frame
speeds (from 500 to 2300 fps),
automatic power conservation
when idle, and LED strobing for
lower power consumption,
enhancing navigation performance. 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 breakthrough crystal-less oscillator.
The result is an overall reduction
in board components and reduced system cost. The EPROM
based microcontroller allows
easy firmware modification, as
well as storage of Vendor and
Product ID™s without an external EEPROM.
This kit is connectable to a PC
via the USB or PS/2 ports. A
single cable with a USB connector and a PS/2 adapter is also
provided. The design automatically detects the type of interface
is attached, allowing further
development of a USB or PS/2
only mouse.
• No mechanical moving parts for
easy maintenance and high
reliability
• Programmable frame speed up to
2300 frames per second (fps)
• High speed motion detector
with accurate motion up to
12 inches-per-second (ips) and
400 counts-per-inch (cpi) resolution
• Open serial interface for communication with microcontrollers
• Power conservation mode during
times of no movement
• Serial port registers for programming and data transfer
• Cypress enCoRe™ CY7C63723 USB
controller
• USB and PS/2 interface combination for PC connection
• Proprietary 8-bit RISC processor,
USB and PS/2-optimized interfaces for high system performance
• 8K Bytes of internal EPROM
provided to enable easy
customization of firmware and
lower cost
• Conforms to USB suspend mode
