ADNK-5023-CY02 Optical Mouse Designer’s Kit Product Overview Description Features Avago Technologies has produced a new optical mouse reference design kit. Based on the new Avago Technologies ADNS-5020-EN small form factor optical mouse sensor and the powerful Cypress CY7C63743 enCoRe USB microcontroller, this reference design kit provides a low cost and yet, feature-rich solution in one neat package. • Complete optical mouse reference design kit The Avago Technologies ADNS-5020-EN optical mouse sensor, an 8-pin staggered dual inline package (DIP), is based on an optimized architecture with good navigation performance. It is able to measure changes in position by optically acquiring sequential surface images with auto frame rate feature and mathematically determining the direction and magnitude of movement. The ADNS-5020-EN along with the ADNS-5100 lens, ADNS-5200 clip and HLMP-ED80-XX000 form a complete, compact optical mouse tracking system. There are no mechanical parts, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly. The sensor is programmed via registers through a three-wire serial port. The Cypress CY7C63743 enCoRe is 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. • ADNS-5020-EN small form factor optical mouse sensor • Optimized architecture for simpler circuitry and minimal number of passive components • No mechanical moving parts for easy maintenance and high reliability • SmartSpeed self-adjusting frame rate for optimum performance • Serial port burst mode for fast data transfer • 500 or 1000 cpi selectable resolution • Single 5.0 volt power supply • Three-wire serial port along with reset (NRESET) pin • Cypress enCoRe CY7C63743 USB controller • USB or PS/2 interface for PC connection • Proprietary 8-bit RISC processor, USB and PS/2optimized interface for high system performance • 8K Bytes of internal EPROM provided to enable easy customization of firmware and lower cost • Conforms to USB suspend mode specifications SW2 middle + 5V SW1 right D1 HLMP-ED80 SW3 left Vcc C7 6 Vcc 19 8 17 J1 VBUS GND D+ D- 1 2 3 4 POWER 8 VCC P1.0 P1.1 P1.2 P1.3 P1.6 P1.7 P0.7 P0.6 P0.5 P0.4 15 11 12 22 23 4 24 SCLK SDIO NCS P1.4 P1.5 XOUT VREG XIN/P2.1 GND P0.0 P0.1 VPP C1 0.1 6 C3 0.1 3.3 7 2 XY_LED NRESET 3 C2 4.7 C4 ADNS-5020-EN REG0 U1 XY_LED 4 Recommended LED bin : D+/SCLK D-/SDAT R13 1.30K 13 P0.2 P0.3 16 1 3 Cypress CY7C63743 21 VDD 0.1 14 5 20 5 7 18 Bin K and above (K, L, M, N,...)
