VT5366 1.8V Optical mouse sensor Data Brief Feature summary ■ 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 9,600 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 ■ Suitable for use with both LED and laser (VCSEL) light sources The VT5366 sensor operates over a wide range of illuminant wavelengths. For devices operating at approximatively 850 nm (IR LED or VCSEL), the on-die automatic exposure controller (AEC) compensates for the change in sensitivity compared to 640nm (red LED). Motion performance can be improved by increasing the current supplied to the navigation LED. Applications ■ USB/PS2, Wireless & BlueTooth Optical Mouse Technical specifications Description The VT5366 has been designed for pin to pin compatibilty with the VT5364(a) and is STMicroelectronics first generally available chip for use in all optical mice applications (USB/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. Resolution CPI programmable up to 3200. Default 800 Pixel size 30.4 µm Array size 20*20 pixels Frame rate Up to 9,600 frames/second High speed motion detector Accurate motion up to 40 ips Clock 6MHz Supply voltage 1.8V Supply current Run (9.6 Kfps) - 9 mA Power down - 10 µA typ. excluding LED Operating temperature [0: 60] °C Package type 7*7mm 32 lead LOQFP (Low profile Optical Quad Flat Pack) Order codes Part number VT5366V032 Package 32-lead LOQFP a. To make use of the new battery level function the PCB and firmware will need to be modified June 2006 Rev 2 For further information contact your local STMicroelectronics sales office. 1/5 www.st.com 5 VT5366 Figure 1.
