cypress公司的CYONS2100是第二代激光导航系统级芯片(SoC),采用高速和高精度的OptiCheck™技术和一流的PSoC技术,器件集成了传感器,USB和MCU功能,可以实现真正的片上鼠标解决方案.主要用于有线和无线激光鼠标,光学跟踪球,以电池为能源的设备以及运动检测等.本文介绍了CYONS2100主要特性, 方框图, 电源连接框图, 有线鼠标电路图以及CY4631 OvationONS™ II 激光游戏鼠标参考设计方框图,电路图和材料清单(BOM).

The CYONS2100 is a member of Cypress Semiconductor’s second generation laser navigation System-on-Chip (SoC) family of products. Powered by the high speed and high precision OptiCheck™ technology, along with the world leading PSoC technology, this family integrates the sensor, USB, and MCU functions into one chip. Bundled with the VCSEL into one package, the combination forms the market’s first true mouse-on-a-chip solution.

The CYONS2100 is the version that is designed for high performance gaming applications. enabled by the Cypress 0.13 micron mixed signal process technology, the device integrates the OptiCheck sensor with full speed USB into a single silicon chip that enables seamless communication between the sensor and MCU/Full Speed USB. The sensor provides the best translation of hand motion into true gaming motion on PC.

This highly integrated solution is programmable. It provides mouse suppliers the ease of use to design a single PCB system and customize their product. With the VCSEL integrated in the same package, designers do not need to calibrate the laser power during the manufacturing process. This greatly increases production throughput and reduces manufacturing costs.

The innovative technology of OvationONS™ II provides high precision, high speed motion tracking, and low power consumption. Designers can select from a family of integration
options, ranging from low power to high performance, to target different types of wired and wireless design applications.

The CYONS2100 solutions have a small form factor. Along with the lens, each package forms a complete and compact laser tracking system. This data sheet describes the detailed technology capabilities of the CYONS2100.

CY4631 - OvationONS™ II 激光游戏鼠标参考设计

The OvationONS II Laser Navigation System on Chip is Cypress Semiconductor’s second generation laser product. It combines the powerful Harvard architecture MCU found in Cypress’ PSoC devices, with a high-speed, high-precision OptiCheck™ sensor. Full-speed USB capabilities are also included in the package.

The CY4631 OvationONS II wired mouse RDK provides a turnkey reference design suitable for PC mouse manufacturers. The kit incorporates the CYONS2100 OvationONS II Laser Navigation System on Chip in a wired mouse design, complete with PCB and mouse skins. This mouse is a multi-function device, featuring 7 buttons, one single-color logo LED, and on tri-color indicator LED. The system includes a total of 2 printed circuit boards: a main board and a daughter card. The main board contains the OvationONS II SoC, left, right, and center (scroll wheel) buttons along with the USB interface. The daughter card includes the front/back buttons, the DPI adjust buttons, the logo LED, and the tri-color LED. In addition, a MiniProg and USB adapter are included in the kit for programming.

The mouse incorporates the CYONS2100 42-pin QFN device for controlling buttons, scroll wheel, LED(s), and full speed USB activity.

Power for the mouse is provided via standard USB 5V bus power.

The mouse has a total of seven buttons. The two top buttons control left and right button mouse functionality. There is a center button as well, which is activated by pressing down on the scroll wheel. Other buttons include two buttons for navigating forward and backward between web pages in a browser. Two more buttons, located on the top side of the mouse, control the DPI resolution of the sensor - one to increase resolution, one to decrease resolution. Finally, a scroll wheel is implemented to scroll up and down within software applications.

The mouse is a human interface device (HID) and interfaces with a PC via a five wire full speed capable USB cable.

The CYONS2100 device has 32k of flash storage for programming. 2k bytes of SRAM for data storage are also available on-chip. The main PCB includes a 5-pin USB connector, which can be used for both programming the MCU, and interfacing with the host PC. A MiniProg-to-USB adapter, board number PDC-9241, is needed for programming the OvationONS II device. This is a separate board included in the kit.
