World’s first programmable single-chip laser navigation system

June 13th, 2008 • Related • Filed Under

Cypress Semiconductor Corp. today announced its second generation laser navigation product family, which is the first in the industry to integrate a laser navigation sensor and programmable Flash based microcontroller on one die. Cypress’s OvationONS™ Laser Navigation Solutions are breakthrough technologies for precision motion-sensing applications. Built around Cypress’s patented OptiCheck™ laser technology, these devices offer a variety of performance differentiations, such as high accuracy tracking at high speed, broad surface coverage, and low power. The product delivers fast, precise, responsive tracking, without the trade-offs between power and performance that characterize traditional image-correlation sensors.

OvationONS devices are strategically designed to simplify assembly, reduce manufacturing costs, and improve yield. The sensor IC, vertical-cavity surface emitting laser (VCSEL), and laser driver are integrated in a single 8×8 QFN package with a self-aligning snap-on lens. Laser output power is calibrated before shipment to meet eye-safety standards. Consequently, there’s no need for laser handling, laser power calibration, or optical alignment. The OvationONS I Laser Navigation Sensor family offers five versions of sensors with targeted applications including trackballs, desktop and high-performance gaming mice, and devices require accurate motion detections. Based on Cypress’s Programmable System-on-Chip (PSoC), the OvationONS II family is the world’s first Laser Navigation System-on-Chip (SoC) solution with integrated M8C 24MHz CPU, USB, up to 32K of Flash, programmable timer, ADC and CapSense(TM). OvationONS II further enhance OvationONS I’s Laser navigation performance along with lower power consumption and smaller form factor.

The new OvationONS™ II Laser Navigation System-on-Chip features the superior surface tracking performance and low-power consumption of Cypress’s patented OptiCheck™ technology integrated with a programmable CPU, USB interface, and a highly-configurable power management unit. 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. The small form factor OvationONS II Laser SoC is based on Cypress’s 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 OvationONS II devices combine easily with an optical lens for simple two-piece assembly measuring only 8×8x4 mm – 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 OvationONS II family targets both wired (USB) and wireless applications. The wired devices feature Full-Speed USB interface and become a mouse-on-chip solution for Human Interface Device (HID) customers. The wireless devices feature SPI interface for communicating with a nearby radio such as Cypress’s WirelessUSB(TM) LP. The wireless devices integrate boost-converter with 0.8-3.6V Vdd input that enables the device to be powered by a single AA battery. The intelligent power management system can also supply power to the radio without external voltage regulator, simplifies board design and reduces BOM cost. The family’s flexible architecture, based on Cypress’s PSoC® mixed-signal array technology, enables fast-to-market designs and in-system debugging using Cypress’s PSoC Designer™ software tool. PSoC Designer provides pre-built, drag-and drop “user modules” that allow designers to complete important design elements very rapidly.
