Description
The VT5363 optical tracking sensor is a complete solid state tracking engine with no moving parts. This single chip optical mouse sensor provides excellent control and precision and works on a wide range of surfaces. The VT5363 supports 2, 3 or 5 button mouse designs with a mechanical scroll wheel encoder. It contains a dual USB/PS2 interface with automatic interface selection and may be powered directly from the USB or PS2 port. A single 6MHz resonator provides all the clock requirements and a minimum of additional passive components are required. An external EEPROM may be used to implement customer specific USB configurations (PID, VID and descriptor string). A specifically designed optical system with integrated light guide and lens is available. This has been optimized for low cost, space saving and ease of mouse manufacture. No kapton tape is required in the assembly process.

Introduction
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 Figure 1.

2.5
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.

Design notes
2.7
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. Figure 4. VT5363 optical centre

3.1
Configuring the VT5363
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. Table 3.

3 button + Z SWBACK, SWFOR 5 button + Z none
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. Table 4.

Mouse assembly guidelines
1. 2. 3. Attach the sensor and all other electrical components onto PCB with the exception of the navigation LED. Form the LED leads and insert the LED into the optical assembly. 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. Route the USB/PS2 lead through the base plate then fit the base plate. Solder the navigation LED leads and trim. Add mouse top case and feet.

LED selection

5.1
LED selection
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. Table 5. Key LED parameters Parameter
Diameter Length Material Luminous Intensity (@20mA) Viewing Angle Mechanical accuracy Colour Wavelength
Recommended Value
5mm 8.6mm AlInGaP 900mcd 20o +/- 2o Red 640nm +/- 50nm
Notes
Important for fit with lens Important for fit with lens For long-term reliability Minimum value Half intensity Accuracy of the die positioning within the LED body
5.3
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.
