Cypress Semiconductor Corp. has expanded its OvationONS family with the introduction of the CYONS1001G laser navigation sensor. CYONS1001G delivers speed and accuracy with low power consumption, using the company's patent-pending OptiCheck technology, which uses a detection scheme that streamlines the signal-processing requirements to maximize performance and reduce the sensor's power consumption, making it suitable for wireless gaming mice, said Cypress.

The OvationONS sensor integrates the detector and laser in a compact 8-by-8mm QFN package with a simple snap-on lens design. The two-piece device has built-in laser eye safety management, which eliminates the need for laser power calibration during mouse assembly to reduce manufacturing cost, said Cypress. The technology's signal-processing load is independent of mouse speed. The OvationONS sensors can simultaneously support full speed (50-inch/s) and full resolution up to 2,800 counts/inch (cpi), maximizing the counts/second recorded by the mouse and avoiding the "deceleration" effect.

Moreover, OptiCheck uses a position-sampling rate as high as 40kHz, allowing the OvationONS sensor to have instant response to changes in tracking direction or speed with significantly reduced latency. Target applications include high-performance gaming, precision graphic design and high accuracy position detection.

The sensor integrates seamlessly with the Cypress Human Interface Devices (HID) portfolio including USB controllers and Wireless USB LP radio-on-a-chip devices to form the main building blocks of wired and wireless computer mice. The CYONS1001G and the Cypress WirelessUSB LP combine to enable the lowest power consumption in wireless gaming mouse available, said the company.

Key features of the product include a hardware resolution of up to 2,800cpi at a speed up to 50-inch/s and continuously variable resolution setting at any value between 400- and 2,800cpi, and can be set differently in X and Y directions. The device also features support for PC cursor speed of up to 140,000 counts/s, position sampling rate at 40,000 samples/s and native 16bit X and 16bit Y directional report rate from the sensor.

The CYONS1001G is priced at less than $6 in volume quantities. Volume shipments are available now.
