VT5363
Introduction
The VT5363 sensor is a single-chip solid state optical tracking engine with no moving parts.
It allows the creation of a high performance, fully featured mouse with the minimum of
external components. The device provides excellent navigation control and precision and
works on a wide range of surfaces.
VT5363 incorporates features that simplify product design and reduce time to market. By
minimising the number of external components, the mouse manufacturer has flexibility for
layout and product design.
ST has worked with optical component suppliers to produce a single piece light guide with
integrated lens, and recommendations for a compatible LED. Details of the optics and LED
are included in this datasheet.The main functional blocks of the VT5363 are shown in

Switches
The VT5363 supports up to 5 switch inputs. These switches provide the standard mouse
functions of LEFT, RIGHT and MIDDLE as well as the advanced functions of BACK and
FORWARD. The switch inputs are all active LOW. An external pull-up resistor is required
between the switch input and the 3V3 supply.
2.6
Scroll wheel
The VT5363 supports the use of an external mechanical shaft encoder with quadrature
outputs to act as a scroll wheel. The EC10E series from Alps are suitable. Pull-up resistors
are required between the ZA and ZB outputs of the shaft encoder and the 3V3 supply. Note
that the two quadrature outputs ZA and ZB are not interchangeable and must be connected
correctly.

2.7
Design notes
Driving the navigation LED
The VT5363 provides an output (NAV_LED) for driving the LED used to illuminate the
mousing surface. This output is active HIGH but cannot be used to drive the navigation LED
directly. An external NPN bipolar transistor is recommended as shown in the reference
schematic. The maximum current through the LED is controlled by a resistor (R1 on the
Reference Schematic).
2.8
LNK_LED output
The VT5363 has an output (LNK_LED) which is high whenever the mouse is active (i.e.
connected to a PC which is not in a suspend state).
The user does not need to use this output to produce a working mouse but it may be used to
drive an additional LED for cosmetic purposes. An external bipolar transistor is required in
the same way as the navigation LED.
2.9
Optical centre
The optical centre of the VT5363 is NOT in the centre of the package, it is offset by 0.243mm in the X-axis and 0.215mm in the Y axis with respect to the centre of the package
as shown below. The PCB designer must take this into account when laying out the PCB.

Sensor orientation on PCB
The VT5363 must be orientated correctly on the PCB in order to move the cursor in the
correct directions when the mouse is moved. This is shown in Figure 5.

Configuring the VT5363
3.1
Selecting USB or PS2 operation
The selection of USB or PS2 interface is performed [automatically] by the VT5363 including
a USB pull-up resistor connected between Pin No. 10 and the DN/DAT line.
3.2
Selecting mouse configuration
The VT5363 may be configured to be one of three different types of mouse.
●
2 button mouse
●
3 button mouse with scroll wheel
●
5 button mouse with scroll wheel
The configuration is achieved by connecting the unused switch inputs to the LNK_LED
output (pin 17). All configurations will report a USB Vendor Identity (VID) of 0x0553 (ST
Microelectronics Imaging Division). The three different configurations will result in 3 different
USB Product Identities (PIDs) and descriptor strings as described in Table 3.

USB descriptor string
A user who wishes to use their own PID, VID and descriptor string may use an external
serial EEPROM to hold this information.
3.3
Changing the CPI
The default CPI ‘Counts Per Inch’ of the VT5363 is 800CPI, this can easily be toggled
between 800/400CPI by the user, by simply holding down the left and right buttons till
LNK_LED goes off. If the PC is shutdown or the mouse unplugged it will return to the default
(800 CPI).
3.4
External EEPROM
The VT5363 supports the use of an external 128 byte serial EEPROM for holding customer
specific information. EEPROM such as the M24C01W from STMicroelectronics are suitable.
The EEPROM must be connected to the SDA and SCL pins of the VT5363. If no EEPROM
is used then these lines should be tied to ground.The EEPROM cannot be programmed by
the VT5363 itself and must be pre-programmed before being fitted to the final PCB.

EEPROM data format
A 128 byte serial EEPROM is used to hold USB configuration information. The lower 64
bytes hold USB PID, VID and string information as shown in the table below. The upper
bytes may be used to hold special setup information, for example to set the resolution to
400cpi (contact STMicroelectronics for details).
Location 127 in the EEPROM must hold the number 0xAA and is used to detect that an
EEPROM has been fitted. If location 127 does not contain 0xAA the EEPROM contents will
be ignored.

Mouse assembly guidelines
Note:
18/25
1.
Attach the sensor and all other electrical components onto PCB with the exception of
the navigation LED.
2.
Form the LED leads and insert the LED into the optical assembly.
3.
Fit the optics with aperture to the PCB using the guideposts and feed the navigation
LED leads through their openings. Take care to keep contamination off the sensor
surface. The aperture should self-align to the VT5363 package.
4.
Route the USB/PS2 lead through the base plate then fit the base plate.
5.
Solder the navigation LED leads and trim.
6.
Add mouse top case and feet.
For more details on the optics (including manufacturers), please refer to the STV-363-R01
user manual.

Overview
There are a number of LEDs from a range of suppliers which will work well with the VT5363.
It is the responsibility of the customer to ensure that the chosen LED works in their specific
implementation. There are various price/performance trade-offs which may be made if the
customer chooses to do so.
5.2
Key LED parameters
The VT5363 system requires a bright visible RED LED in a standard 5mm (T1 3/4) package.
The ideal viewing angle is 20o and the intensity should be at least 900mcd at a forward
current of 20 mA. The key LED parameters are listed in Table 5.

VCSEL and IR illumination
The VT5363 sensor will operate over a wide range of illuminant wavelengths. For devices
operating at approx 850 nm (IR LED or VCSEL), the on-die automatic exposure controller
(AEC) will compensate for the change in sensitivity compared to 640nm (red LED).
Navigation performance may be improved by increasing the illuminated device drive.
