ADNK-7053-ND24
2.4GHz Wireless Laser Mouse Designer's
Description Avago Technologies producing wireless laser mouse reference design kit. Based Avago Technologies ADNS-7050 power laser mouse sensor, Texas Instruments MSP430F1222 microcontroller, Nordic Semiconductor nRF2402 2.4GHz transmitter nRF2401A 2.4GHz transceiver, Cypress CY7C63231A enCoRe microcontroller, this reference design provides power efficient feature-rich solution neat package. Avago Technologies ADNS-7050 power laser mouse sensor, 18-pin staggered dual inline package (DIP), based LaserStream Technology, which measures changes position optically acquiring sequential surface images (frames) mathematically determining direction magnitude movement. highperformance, power architecture capable sensing high-speed mouse motion while prolonging battery life, performance areas essential demanding wireless applications. ADNS-7050 sensor along with ADNS6120 ADNS-6130-001 lens, ADNS-6230-001 clip ADNV-6340 VCSEL form complete compact laser mouse tracking system. There moving part, which means high reliability less maintenance user. addition, precision optical alignment required, facilitating high volume assembly.
Features Complete laser mouse reference design Windows® 98SE, Windows 2000 Windows compatibility low-speed compliance User identity code avoid conflict with other devices High reliability LaserStream Technology Smooth surface navigation Enhanced SmartSpeed self-adjusting frame rate optimum performance High speed motion detection resolution mechanical moving parts high data rate 2.4GHz link Transmission data rate Mbps meters communication distance Self-adjusting power-saving modes longest battery life Laser fault detect circuitry on-chip Safety Compliance Minimal number passive components
Texas Instruments MSP430F1222 ultra low-power mixed signal microcontroller with built-in 16-bit timer, 10-bit converter with integrated reference data transfer controller (DTC) twenty-two pins. addition, MSP430F1222 microcontroller built-in communication capability using asynchronous (UART) synchronous (SPI) protocols. architecture, combined with five power modes optimized achieve extended battery life wireless application. Nordic nRF2402 nRF2401A power single-chip radio transmitter transceiver world wide band. entire transmitter transceiver including inductors filters integrated each single chip respectively which gives lowest cost solution user. configurations nRF2402 transmitter nRF2401A transceiver done standard serial interface. devices include ShockBurst engine which allow high datarates using datarates between microcontroller device, will also
automatically validate packets adress CRC, further reducing microcontrollers processing tasks. Cypress CY7C63231A enCoRe revolutionary chip that integrates numerous common components, including breakthrough crystal-less oscillator. result overall reduction board components reduced system cost. EPROM based microcontroller allows easy firmware modification, well storage Vendor Product without external EEPROM. This connectable port. based 2.4GHz technology, data generated from displacement detection button status laser mouse encoded with pre-defined serial type protocol handled firmware MCU. stage, encoded data used GFSK modulation. captured data from receiver stage decoded with corresponding packet format used mouse applications. final data sent host through interface.
