ADNK-2133
Optical Mouse Designer’s Kit
Product Overview
Description
Avago Technologies and Freescale Semiconductor have joined forces to produce a new wireless optical mouse reference design kit. Based on the new Avago ADNS- 2030 low power optical mouse sensor and the powerful Freescale MC68HC908QY4/MC68HC908JB12 USB mi crocontroller, this reference design kit provides a power efficient and feature-rich solution. The Avago ADNS-2030 optical mouse sensor, a 16‑pin staggered dual inline package (DIP), is based on innovative power management architecture with relatively good navigation performance. It is able to measure changes in position by optically acquiring sequential surface images of over 2300 fps and mathematically determining the
direction and magnitude of movement. The ADNS-2030 along with the HDNS-2100 lens, HDNS- 2200-001 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 op tical alignment is not required, facilitating high volume assembly. The sensor is programmed via registers through a four-wire serial port. The Freescale MC68HC908QY4/ MC68HC908JB12 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08 Family is a Complex Instruction Set Computer (CISC) with a Von Neumann architecture. All MCUs in the family use
the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

The MC68HC908QY4 has an internal oscillator circuit which can generate a clock of 12.8 MHz with no external components needed. The auto wakeup module generates a periodic interrupt during stop mode to wake the part up without requiring an external signal. These features make the MC68HC908QY4 MCU suited for wireless optical mouse applications. The features of the MC68HC908JB12 include a configu rable universal serial bus (USB), which makes this MCU suited for personal computer human interface devices (HID) applications, such as mice. The enhanced timer
Sensor
function also allows it to capture and decode data easily, especially for high data rate wireless HID applications. This kit is connectable to a PC via the USB port. It is also based on the 27 MHz RF technology, the data generated from displacement detection/button status in the optical mouse is encoded with a pre-defined serial type protocol handled by firmware in the MCU. In the RF stage, the en coded data is used for FSK modulation. The captured data from the RF receiver stage is decoded with a correspond ing packet format used for mouse applications. The final data is sent to the host through the USB interface.
