Serial interface engine provides USB 2.0 for MCUs
Cypress Semiconductor has expanded its USB 2.0 product line with the introduction of the EZ-USB SX2 intelligent serial interface engine (SIE).
The precision, small form-factor and low-power of the OvationONS sensor provides the flexibility to design with a variety of sizes and materials for trackballs.
Additionally, Cypress' 2.4-GHz WirelessUSB LP radio and enCoRe III microcontroller deliver flawless and low-power wireless connectivity to the keyboard.
OvationONS laser navigation products feature Cypress' OptiCheck technology, a detection scheme that maximises tracking performance and reduces power consumption versus traditional image capture/correlation techniques.

Software gets to grips with the largest CPLDs
The latest version of Cypress Semiconductor's In-System Reprogrammable (ISR) software is now available from the company's website.
Combined with Cypress' ultra-low power wireless technology, the total human interface device (HID) solution prolongs battery life for the keyboard.
The interference immunity of Cypress' AgileHID protocol allows the keyboard to operate uninterrupted in the home environment, where the 2.4GHz spectrum is crowded with signals from Wi-Fi, microwaves, cordless phones and other devices.
"Cypress' OvationONS I laser sensor and wireless HID solution deliver the precise navigation and low power consumption we wanted for our media centre keyboard", said Roger Tsai, President of Input Device Division at BTC.
"In addition to the benefits of the technology, Cypress' one-stop-shopping HID portfolio simplified our design process and cut our time to market".
Shuo Zhang, Vice President of Sales and Marketing for Cypress' Optical Navigation Solutions said "Our technology enabled BTC to incorporate a trackball and wireless connectivity into their multimedia keyboard without having to sacrifice tracking performance, battery life or reliability".
The OvationONS I family integrates a vertical cavity surface emitting laser (VCSEL) and detector in a compact 8 x 8mm QFN package with a simple snap-on lens design.
The simple two-piece device has built-in laser eye safety management, eliminating the need for laser power calibration during assembly to reduce manufacturing complexity and cost.
In addition to a keyboard trackball, the OvationONS I family also includes devices targeted for laser mouse applications.
OptiCheck technology's signal-processing speed and power consumption is independent of the sensor's tracking speed.
The family uses a position-sampling rate as high as 40kHz, allowing the sensors to have instant response to changes in tracking direction or speed with significantly reduced latency.
