1 / 30 page  December 2006 Rev 1 1/30 30 VT5366 1.8V optical mouse sensor Features ■ Pin compatible with VT5364 ■ Can be used (with external MCU) in all optical mouse applications ■ Single +1.8V Supply ■ Very low power operation, enabling long battery life ■ CPI programmable up to 3200 (default 800 cpi) ■ Up to 9,375 frames per second ■ Tracking at up to 40 ips ■ I2C interface ■ On-chip ADC for voltage level reporting ■ Proven, high volume package technology - smallest package currently available on market ■ Minimal external circuitry ■ Low battery indicator ■ Suitable for use with both LED and laser (VCSEL) light sources ■ Reference Designs available ■ Applications: USB/PS2, Wireless & Bluetooth optical mice Description The VT5366 has been designed for pin to pin compatibility with the VT5364(a) and is STMicroelectronics first generally available chip for use in all optical mice applications: Wired - USB (Low and Full Speed) and PS2; Wireless - 27MHz/2.4GHz and BlueTooth. The device has been designed to provide long battery life whilst enabling excellent navigation control and precision on a wide range of surfaces. Housed in the smallest, currently available, package (7mmx7mm), the chip is suitable for use in small form-factor mice demanded by laptop users. Minimal external circuitry is required thereby reducing BOM and assembly costs. The VT5366 sensor will operate over a wide range of illuminant wavelengths. For devices operating at approx 850nm (IR LED or VCSEL), the on-die automatic exposure controller (AEC) will compensate for the change in sensitivity compared to 640nm (red LED). Motion performance can be improved by increasing the current supplied to the navigation LED. A specifically designed LED optical system with integrated light guide and lens is available along with an aperture piece which clips the package in place aligning the optics. This has been optimized for low cost, space saving and ease of assembly in high volume mouse manufacture. No kapton tape is required in the assembly process. Please contact STMicroelectronics for supplier details. Technical specifications a. To make use of the new battery level function the PCB and firmware will need to be modified Resolution CPI programmable up to 3200. Default 800 CPI Pixel size 30.4 µm Array size 20*20 pixels Frame rate Up to 9,375 frames/second High speed motion detector Accurate motion up to 40 ips Clock 6MHz Supply voltage 1.8V Supply current RUN (9.6Kfps) - 9mA Power Down - 10µA typ. excluding LED Operating temperature [0: 60] °C Package type 7*7mm 32 lead LOQFP (Low profile Optical Quad Flat Pack) www.st.com |
