ADNS-5030
Low Power Optical Mouse Sensor
Data Sheet
www.DataSheet4U.com
Description
The Avago Technologies ADNS-5030 is a low power, small
form factor optical mouse sensor. It has a new low-power
architecture and automatic power management modes,
making it ideal for battery, power-sensitive applications
– such as cordless input devices.
The ADNS-5030 is capable of high-speed motion
detection – up to 14 ips and 2G. In addition, it has an
on-chip oscillator and LED driver to minimize external
components.
The ADNS-5030 along with the ADNS-5100/ADNS-5100-
001 lens, ADNS-5200 clip, and HLMP-ED80 LED form a
complete and compact mouse tracking system. There
are no moving parts, which means high reliability and
less maintenance for the end user. In addition, precision
optical alignment is not required, facilitating high volume
assembly.
The sensor is programmed via registers through a four-
wire serial port. It is housed in an 8-pin staggered dual
in-line package (DIP).
Theory of Operation
The ADNS-5030 is based on Optical Navigation Technol-
ogy, which measures changes in position by optically
acquiring sequential surface images (frames) and math-
ematically determining the direction and magnitude of
movement.
The ADNS-5030 contains an Image Acquisition System
(IAS), a Digital Signal Processor (DSP), and a four wire
serial port.
The IAS acquires microscopic surface images via the lens
and illumination system. These images are processed
by the DSP to determine the direction and distance of
motion. The DSP calculates the Dx and Dy relative dis-
placement values.
An external microcontroller reads the Dx and Dy informa-
tion from the sensor serial port. The microcontroller then
translates the data into PS2, USB, or RF signals before
sending them to the host PC.

PCB Assembly Considerations
1. Insert the sensor and all other electrical components
into PCB.
2. Insert the LED into the assembly clip and bend the leads
90 degrees.
3. Insert the LED clip assembly into PCB.
4. Wave solder the entire assembly in a no-wash solder
process utilizing solder fixture. The solder fixture is
needed to protect the sensor during the solder process.
It also sets the correct sensor-to-PCB distance as the
lead shoulders do not normally rest on the PCB surface.
The fixture should be designed to expose the sensor
leads to solder while shielding the optical aperture
from direct solder contact.
5. Place the lens onto the base plate.
6. Remove the protective kapton tape from optical
aperture of the sensor. Care must be taken to keep
contaminants from entering the aperture. Recommend
not to place the PCB facing up during the entire mouse
assembly process. Recommend to hold the PCB first
vertically for the kapton removal process.
7. Insert PCB assembly over the lens onto the base plate
aligning post to retain PCB assembly. The sensor
aperture ring should self-align to the lens.
8. The optical position reference for the PCB is set by the
base plate and lens. Note that the PCB motion due to
button presses must be minimized to maintain optical
alignment.
9. Install mouse top case. There MUST be a feature in
the top case to press down onto the PCB assembly to
ensure all components are interlocked to the correct
vertical height.

Power Management Modes
The ADNS-5030 has three power-saving modes. Each
mode has a different motion detection period, affecting
response time to mouse motion (Response Time). The
sensor automatically changes to the appropriate mode,
depending on the time since the last reported motion
(Downshift Time). The parameters of each mode are
shown in the following table.
Response Time
Mode (Typical)
Rest 1 14 ms
Rest 2 68 ms
Rest 3 340 ms
Downshift Time
(Typical)
<1s
7s
410 s
LED Mode
For power savings, the LED will not be continuously on.
ADNS-5030 will pulse the LED only when needed.
Synchronous Serial Port
The synchronous serial port is used to set and read pa-
rameters in the ADNS-5030, and to read out the motion
information.
The port is a four wire serial port. The host micro-control-
ler always initiates communication; the ADNS-5030 never
initiates data transfers. SCLK, MOSI, and NCS may be
driven directly by a micro-controller. The port pins may be
shared with other SPI slave devices. When the NCS pin is
high, the inputs are ignored and the output is tri-stated.
www.DataSheet4U.com
The lines that comprise the SPI port:
SCLK: Clock input. It is always generated by the master
(the micro-controller).
MOSI: Input data. (Master Out/Slave In)
MISO: Output data. (Master In/Slave Out)
NCS: Chip select input (active low). NCS needs to be low
to activate the serial port; otherwise, MISO will be
high Z, and MOSI & SCLK will be ignored. NCS can
also be used to reset the serial port in case of an
error.
Chip Select Operation
The serial port is activated after NCS goes low. If NCS
is raised during a transaction, the entire transaction is
aborted and the serial port will be reset. This is true for all
transactions. After a transaction is aborted, the normal
address-to-data or transaction-to-transaction delay is
still required before beginning the next transaction. To
improve communication reliability, all serial transac-
tions should be framed by NCS. In other words, the port
should not remain enabled during periods of non-use
because ESD and EFT/B events could be interpreted as
serial communication and put the chip into an unknown
state. In addition, NCS must be raised after each burst-
mode transaction is complete to terminate burst-mode.
The port is not available for further use until burst-mode
is terminated.
Write Operation
Write operation, defined as data going from the micro-
controller to the ADNS-5030, is always initiated by the
micro-controller and consists of two bytes. The first byte
contains the address (seven bits) and has a “1” as its MSB
to indicate data direction. The second byte contains
the data. The ADNS-5030 reads MOSI on rising edges of
SCLK.
