Agilent ADNS-2001 Optical Mouse Sensor Data Sheet • High speed motion detector – Accurately measures up to 16 inches per second at 400 cpi Description The ADNS-2001 is a low-cost reflective optical sensor that provides a non-mechanical tracking engine for implementing a computer mouse. It is based on optical navigation technology which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. The sensor is mounted in a plastic optical package and designed to be used with the HDNS-2100 (Lens), HDNS-2200 (LED Assembly Clip) and HLMP-ED80 (High Light Output 639 nm LED), providing a complete and compact tracking engine. This optical tracking engine has no moving parts and requires no precision optical alignment enabling high volume system assembly. The ADNS-2001 offers a PS/2 or quadrature output mode for interface flexibility. Resolution is specified as 400 cpi at rates of motion up to 16 inches per second. Features • Optical navigation technology – Superior precision and smooth navigation optimized for desktop and portable mouse applications – No mechanical moving parts, provides high reliability and needs no maintenance • Complete compact 2-D motion sensor – Easy implementation and design flexibility – Replaces mechanical ball system in traditional mice • Two selectable output modes – Two channel quadrature output mode (X and Y direction) which emulates encoder phototransistors – Standard 3-button PS/2 output mode • Accurate navigation over a wide range of surfaces – Enables mouse to be used with or without a mouse pad • Power conservation mode during no motion • Compatible with high volume manufacturing processes – Requires no precision optical alignment – Wave solderable • 33% faster than HDNS-2000 – 2000 fps (@ 24 MHz) Applications • Computer mice for desktop PCs, workstations, and portable computers • Trackball • Integrated input devices Caution: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. Theory of Operation The ADNS-2001 is based on Optical Navigation Technology. It contains an Image Acquisition System (IAS), Digital Signal Processor (DSP), and a mode selectable PS/2 or quadrature output converter. The IAS acquires images of microscopic surface images via the lens and illumination IMAGE ACQUISITION SYSTEM system provided by the HDNS2100, HDNS-2200, and the HLMP-ED80. These images are further processed by the DSP to determine direction and distance of motion. The DSP generates a stream of delta x and delta y relative displacement values which are then communicated to the output converter. This converter provides a PS/2 3-button output, replacing existing mouse microcontrollers, or two channel quadrature output, for direct interface to existing mouse microcontrollers. While the part can be run at 24 MHz in quadrature mode, 18 MHz is recommended for PS/2 mode. PS/2 or QUAD OUTPUT CONVERTER DIGITAL SIGNAL PROCESSOR A 2001 XYYWWZ Figure 1. ADNS-2001 block diagram.

Due to the Cypress implementation of USB suspend mode support, the NRESET pin of the ADNS-2001 must be reset using a line from the Cypress chip. The reason for this is that the Cypress chip does not configure the port input pins until after it has received a bus reset from the USB port. The unconfigured input port pins present a 16 KΩ pullup to VCC. If a cap is used on NRESET (pin 15), this pullup will result in the ADNS-2001 seeing a high on the MODE pin and powering up in the PS/2 mode. 2. The quadrature input pins of the Cypress part must be programmed to be Hi-Z, instead of the normal current pulldowns. This ensures that the ADNS-2001 will be able to pull the quadrature lines high over all conditions of voltage and temperature. 3. 0.1 µF between pins 7 and 8 must be ceramic, and must be trace lengths less than 5 mm. 5 Recommended LED Bin Table LED Bin Category K L M N P Q R S T R1 Value 69.8 Ω 69.8 Ω 69.8 Ω 69.8 Ω 69.8 – 78.7 Ω 69.8 – 93.1 Ω 69.8 – 113 Ω 69.8 – 137 Ω 69.8 – 169 Ω The 69.8 Ω resistor is determined by the absolute maximum rating of 50 mA for the HLMP-ED80.

The mouse checks the DATA line. If the line is low, the system has data to transmit. The DATA line is set inactive when the start bit (always 0) is placed on the DATA line. 2. The mouse samples the DATA line for each bit while the CLK line is high. Data must be stable within 1 microsecond after the rising edge of the CLK line. 3. The mouse checks for a high stop bit after the 10th CLK. If the DATA line is low, the mouse continues to clock until the DATA line becomes high, then clocks the line-control bit, and at the next opportunity sends a Resend command to the system. 4. The mouse pulls the DATA line low, producing the line-control bit. 5. The host can pull the CLK line low, inhibiting the mouse.
