ADNS-5090
Low Power Optical Mouse Sensor
Data Sheet
Description
Features
The Avago Technologies ADNS-5090 is a low power, small
form factor optical mouse sensor. It has a low-power architecture and automatic power management modes, making it ideal for battery, power-sensitive applications – such
as cordless input devices.
Low Power Architecture
The ADNS-5090 is capable of high-speed motion detection – up to 30ips and 8G. In addition, it has an on-chip oscillator and LED driver to minimize external components.
’Smart’ LED Current Switching depending on surface
brightness
The ADNS-5090 along with the ADNS-5110-001 lens, LED
clip, and HLMP-EG3E-xxxxx LED form a complete and compact mouse tracking system. There are no moving parts
and this translates to 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 fourwire serial port. It is housed in an 8-pin staggered dual inline package (DIP).
NOTE: The ADNS-5090 Low Power Optical Mouse Sensor is not
designed for use with blue LEDs. The ADNS-4000 product is available
from Avago for use with Blue LEDs.

Theory of Operation
The ADNS-5090 is based on Optical Navigation Technology, which measures changes in position by optically
acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of
movement.
The ADNS-5090 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 displacement values.
An external microcontroller reads and translates the Dx
and Dy information from the sensor serial port into PS2,
USB, or RF signals before sending them to the host PC.

Overview of Optical Mouse Sensor Assembly
Avago Technologies provides an IGES file drawing describing the base plate molding features for lens and PCB alignment. The ADNS-5090 sensor is designed for mounting on
a through-hole PCB. There is an aperture stop and features
on the package that align to the lens. The ADNS-5110-001
lens provides optics for the imaging of the surface as well
as illumination of the surface at the optimum angle. Features on the lens align it to the sensor, base plate, and clip
with the LED. The LED clip holds the LED in relation to the
lens. The LED must be inserted into the clip and the LED’s
leads formed prior to loading on the PCB.
The HLMP-EG3E-xxxxx LED is recommended for illumination.

PCB Assembly Considerations
4. This sensor package is only qualified for wave-solder
process.
5. 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.
10. 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.

6. Place the lens onto the base plate.
7. 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.
8. 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.

Synchronous Serial Port
Power Management Modes
The synchronous serial port is used to set and read parameters in the ADNS-5090, and to read out the motion
information. The port is a four wire serial port. The host
micro-controller always initiates communication; the
ADNS-5090 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
at tri-state.
The ADNS-5090 has three power-saving modes. Each
mode has a different motion detection period with its respective response time to mouse motion. Response Time
is the time taken for the sensor to ‘wake up’ from rest mode
when motion is detected. When left idle, the sensor automatically changes or downshift from Run mode to Rest1,
to Rest2 and finally to Rest3 which consumes the least current. Do note that current consumption is the lowest at
Rest3 and highest at Rest1, however time required for sensor to respond to motion from Rest1 is the shortest and
longest from Rest3. Downshift Time is the elapsed time
(under no motion condition) from current mode to the
next mode for example, it takes 10s for the sensor that is
in Rest1 to change to Rest2. The typical response time and
downshift time for each mode is shown in the following
table. However, user can change the default time setting
for each mode via register 0x0e through 0x13.
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 transactions 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.
‘Smart’ LED Current Switching
ADNS-5090 is designed with ‘smart’ LED feature, an auto or
self-adjusting LED current switching between the low and
high current settings depending on the brightness of the
tracking surface. If the surface is sufficiently bright to the
sensor, lower LED current will be selected. When tracking
on a darker surface, the higher current setting will be used.
This feature is one of the power saving features in this sensor controlled by AUTO_LED_CTRL register (0x43).

This register is used to control the frame rate. The value in this register is used to add frame
idling time, which effectively reduces the frame rate..
frame_idle_time (in clock counts) = (register value) * 32
Frame period (in clock counts) = shutter_time (reg 0x06 and reg 0x07) + (3400 clocks) +
frame_idle_time
When this register is set to 0xf0, the typical frame rate is about 2250 fps @26MHz

Data Type:
Eight bit unsigned integer
USAGE:
This register is used to set the feature of MOTION interrupt output. If MOT_S bit is clear, the
MOTION pin is level-sensitive. With active low (MOT_A bit is clear) level-sensitive configuration,
the MOTION pin will be driven low when there is motion detected indicating there is motion
data in DELTA_X and DELTA_Y registers. The mouse microcontroller can read MOTION_ST
register, DELTA_X register, and then DELTA_Y register sequentially. After all the motion data
has been read, DELTA_X and DELTA_Y registers will be zero, the MOTION pin will be driven
high by the sensor.
If MOT_S is set, the MOTION pin is edge sensitive. If MOT_A is also set, it means active high or
rising edge triggered. Whenever there is motion detected by the sensor, a pulse (~230us) will
be sent out through this pin. This pulse can be used to trigger or wake the controller up from
its sleep mode to read motion data from the sensor. The controller can then read MOTION_ST
register, DELTA_X register, and then DELTA_Y register sequentially. (Refer to Motion Function
for more information)

Note: To change the burst mode starting address from default (DELTA_X or 0x03) pull the NCS
low, set the BURST_READ_FIRST register with the burst mode starting address, read register
0x63 for burst reads, and terminate the burst reads by pulling NCS high. This must be repeated
each time when performing burst reads with address other than default.

Data Type:
Eight bit unsigned integer
USAGE:
This register enables AUTO LED current switching. This is a ‘smart’ LED feature whereby the
LED current is self adjusting between the low and high current settings (bit 3:1) according to
the brightness of the tracking surface if this feature is enabled (via clearing bit 0). The brighter
the surface, the lower the LED current will be. If A_LED_DIS (bit 0) is set, this means AUTO
LED mode is disabled, then the LED current is determined by LSEL[1:0] setting in LED_CTRL
register (0x40).

Note: When AUTO LED is enabled, the AUTO LED current will be switched between low and
high current setting determined by LED_LO and LED_HI [1:0]. If LED_LO current setting is
higher than the LED_HI, the current will be based on the higher setting. For example if LED_
LO is 20mA and LED_HI is 15mA, the AUTO LED current will be fixed at 20mA.

Read operation to REST_MODE_CONFIG indicates which mode the sensor is in. Write operation
into this register will force the sensor into rest modes (Rest 1, 2 or 3). Write the value 0x40 into
0x45 register to force sensor into Rest 1, 0x80 to Rest 2 or 0xC0 to Rest 3. To get out of any
forced rest mode, write 0x00 into this register to set back to normal mode.
Note: Write 0x00 to register 0x22 during start up sensor initialization to enable configuration
to this register.

USAGE:
This register is used to enable burst mode. Burst is initiated by a read of this register, which
will then return continuous data starting from the address stored in BURST_READ FIRST
register through register 0x09. If burst operation is not terminated at this point, the internal
address counter stops incrementing and register 0x09 value will be returned repeatedly. Burst
operation is terminated when NCS is asserted high. For more information, refer to Burst Mode
Operation.
