Single-chip laser system makes mouse design, manufacture a snap

Integrates high-precision sensing system, optical signal processing, and system control on a single die

The first device to integrate a laser navigation sensor and programmable-flash microcontroller on one die, the OvationONS II Laser Navigation System-on-Chip series greatly simplifies design and manufacturing of computer mice, gaming controls, and other tracking devices. Said to offer superior surface-tracking performance and low-power consumption through the use of OptiCheck technology, the chip also integrates a USB interface and a highly configurable power management unit, so that only two pieces — the chip and an optical lens — are needed for the guts of a pointing device.

The 8 x 8 x 4-mm two-piece assembly supports 0.8 to 5.5-V operations, making it small enough to fit on the head of an AA battery, which can power it in wired or wireless configurations. The device uses a vertical-cavity surface-emitting laser, meeting Class I eye-safety requirements and eliminating the need for power calibration or optical alignment at the factory.

The device provides a position-sampling rate as high as 80 kHz, so it responds to changes in tracking direction or speed with practically no latency. Five versions are available: the CYONS2000 and CYONS2100 for USB computer mice and gaming pointers respectively and, similarly, CYONS2001 and CYONS2101 for wireless units; the CYONS2110 supports both USB and wireless high-end applications. All come in 42-pin QFN packages and share the same pinout. (From less than $2.50 ea / 100,000 — available now.)
