ADNK-7053-ND24 USB 2.4GHz RF Wireless Laser Mouse Designer’s Kit
Product Overview
Description
Features
Avago Technologies is producing a new wireless laser mouse reference design kit. Based on the new Avago Technologies ADNS-7050 low power laser mouse sensor, Texas Instruments MSP430F1222 microcontroller, Nordic Semiconductor nRF2402 2.4GHz RF transmitter and nRF2401A 2.4GHz RF transceiver, Cypress CY7C63231A enCoRe USB microcontroller, this reference design kit provides a power efficient and feature-rich solution in one neat package.
• Complete laser mouse reference design kit
The Avago Technologies ADNS-7050 low power laser mouse sensor, an 18-pin staggered dual inline package (DIP), is based on LaserStream Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. Its highperformance, low power architecture is capable of sensing high-speed mouse motion while prolonging battery life, two performance areas essential in demanding wireless applications. The ADNS-7050 sensor along with the ADNS6120 or ADNS-6130-001 lens, ADNS-6230-001 clip and ADNV-6340 VCSEL form a complete and compact laser mouse tracking system. There is no moving part, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly.
• Windows® 98SE, Windows 2000 and Windows XP compatibility • USB 2.0 low-speed compliance • User identity code to avoid conflict with other devices • High reliability • New LaserStream Technology • Smooth surface navigation • Enhanced SmartSpeed self-adjusting frame rate for optimum performance • High speed motion detection up to 20 ips and 8G • 800 cpi resolution • No mechanical moving parts • A high data rate 2.4GHz RF link • Transmission data rate up to 1 Mbps • 15 meters communication distance • Self-adjusting power-saving modes for longest battery life • Laser fault detect circuitry on-chip for Eye Safety Compliance • Minimal number of passive components
The Texas Instruments MSP430F1222 is the ultra low-power mixed signal microcontroller with a built-in 16-bit timer, 10-bit A/D converter with integrated reference and data transfer controller (DTC) and twenty-two I/O pins. In addition, the MSP430F1222 microcontroller has built-in communication capability using asynchronous (UART) and synchronous (SPI) protocols. The architecture, combined with five low power modes is optimized to achieve extended battery life on wireless application. The Nordic nRF2402 and nRF2401A are the low power single-chip radio transmitter and transceiver for the world wide 2.4 - 2.5 GHz ISM band. The entire transmitter and transceiver including all inductors and filters are integrated in each single chip respectively which gives the lowest cost solution to the end user. All configurations of the nRF2402 transmitter and nRF2401A transceiver are done via a standard serial interface. The nRF devices include the ShockBurst engine which allow for high datarates on air using low datarates between the microcontroller and the nRF device, it will also
automatically validate the packets adress and CRC, further reducing the microcontrollers processing tasks. The Cypress CY7C63231A enCoRe i s a revolutionary chip that integrates numerous common components, including breakthrough crystal-less oscillator. The result is an overall reduction in board components and reduced system cost. The EPROM based microcontroller allows easy firmware modification, as well as storage of Vendor and Product IDs without an external EEPROM. This kit is connectable to a PC via the USB port. It is based on the 2.4GHz RF technology, the data generated from displacement detection / button status in the laser mouse is encoded with a pre-defined serial type protocol handled by firmware in the MCU. In the RF stage, the encoded data is used for GFSK modulation. The captured data from the RF receiver stage is decoded with a corresponding packet format used for mouse applications. The final data is sent to the host through the USB interface.
