Cypress Semiconductor Corp. has introduced its second-generation laser navigation product family, which the company touts as the first in the industry to integrate a laser navigation sensor and programmable flash-based MCU on one die. Aimed at wired and wireless mice applications, the OvationONS II laser navigation SoC is said to feature excellent surface tracking performance and low-power consumption thanks to Cypress' patented OptiCheck technology integrated with a programmable CPU, USB interface, and a highly configurable power management unit.

The OvationONS II devices can be easily combined with an optical lens for a two-piece assembly measuring only 8mm x 8mm x 4mm, which is small enough to fit completely on the head of an AA battery, Cypress said. The integration and programmability of the device are said to ease mouse design and manufacturing processes.

The OvationONS II laser SoC is based on Cypress' 0.13?m SONOS mixed-signal process technology, which is said to deliver low power and high performance. The OvationONS II family supports 0.8V to 5.5V operation, enabling both wired and wireless applications with a single AA battery. The family's architecture, based on Cypress' PSoC mixed-signal array technology, is said to enable fast-to-market designs and in-system debugging using the company's PSoC Designer software tool with pre-built, drag-and drop "user modules."

In addition, the OvationONS II SoC integrates the 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, which further simplifies the manufacturing process and reduces assembly costs. 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.

The family includes the following products:

? CYONS2000: USB interface targeted at mainstream wired mice
? CYONS2001: wireless interface targeted at mainstream wireless mice
? CYONS2100: USB interface targeted at wired gaming mice
? CYONS2101: wireless interface targeted at wireless gaming mice
? CYONS2110: USB and wireless interfaces at targeted at high-end applications.

All of the devices are available in 42-pin QFN packages.

The CYONS2000 is priced under $2.50 in quantities over 100,000 units for high-volume applications such as OEM (PC bundled) wired mice. The OvationONS II Laser SoC is currently sampling, with production expected in 2H 08.
