SoC optosensor for mice needs no microcontroller

Eliminating the need for an external microcontroller and requiring fewer passive components, the ADNS-2700 system-on-chip (SoC) LED-based optical sensor is said to offer the smallest pincount of any device of its type on the market. Being compact and highly integrated, it can simplify the design and lower the system costs for mice, trackballs, and other pointing devices.

With a footprint of just 9.9 x 9.9 mm and total body height of 4.3 mm, the sensor contains an Image Acquisition System (IAS), a DSP, and a USB stream output in an 8-pin DIP. The sensor also provide an integrated oscillator and pull-up resistor to further reduce the need for external components,

The optical sensor provides motion detection of up to 30 in./s (ips), programmable resolution ranges from 250 to 1250 counts/in. (cpi), and 8 G acceleration detection.

To streamline customization, on-chip write-once memory lets designers select the resolution setting and sensor orientation, eliminating the need for a software driver, and program their product and vendor identification information. The sensor does not require precision optical alignment, facilitating high-volume assembly. (Less than $0.75 ea / 1,000 — available now.)
