Single-chip laser navigation system simplify mouse design, manufacturing

The OvationONSTM II laser navigation SoC is the “first” in the industry to integrate a laser navigation sensor and programmable Flash based microcontroller on one die. The SoC features the superior surface tracking performance and low-power consumption of the patented OptiCheck technology integrated with a programmable CPU, USB interface, and a highly-configurable power management unit. The OvationONS II devices combine easily with an optical lens for simple two-piece assembly measuring only 8mm x 8mm x 4mm – small enough to fit completely on the head of an AA battery.

The integration and programmability of the device combine to greatly simplify customers’ design and manufacturing processes. The small form factor OvationONS II Laser SoC is based on the 0.13-micron SONOS mixed-signal process technology, which delivers low power and high performance. The OvationONS II family is designed to support 0.8V to 5.5V operations, enabling both wired and wireless applications with a single AA battery. The family’s flexible architecture, based on PSoC mixed-signal array technology, enables fast-to-market designs and in-system debugging using PSoC Designer software tool. PSoC Designer provides pre-built, drag-and drop “user modules” that allow designers to complete important design elements rapidly.

The OvationONS II SoC integrates the vertical-cavity surface-emitting laser (VCSEL) in the package, meeting Class I eye-safety requirements. The device eliminates the need for power calibration of the VCSEL or for optical alignment at a customer’s factory, simplifying the manufacturing process and reducing assembly costs. In addition, all products in the family share the same pin-out and are mechanical compatible, enabling customers to offer multiple products without changing PCB layout and mechanical system alteration.
