Programmable Laser Navigation Chip Simplifies Mouse Design

Integrating a precision navigation sensing system, optical signal processing, and system control on a single die, the OvationONS II embarks as the industry's first SoC to integrate a laser navigation sensor and programmable Flash based microcontroller into one chip. The device employs patented OptiCheck technology integrated with a programmable CPU, USB interface, and a configurable power management unit. It combines easily with an optical lens for a two-piece assembly measuring 8 mm x 8 mm x 4 mm. The device supports 0.8V to 5.5V operations, enabling both wired and wireless applications with a single AA battery, and integrates the VCSEL, meeting Class I eye-safety requirements. Additionally, it eliminates the need for power calibration of the VCSEL or for optical alignment. CYPRESS SEMICONDUCTOR CORP., San Jose, CA. (800) 541-4736.
