Specifications of ADNK-5033-FS27

• Main Purpose: Reference Design, Optical Mouse
• Utilized Ic / Part: ADNS-5030
• Wireless Frequency: 27 MHz
• Interface Type: USB
• Modulation: FSK
• For Use With/related Products: MC68HC908QY4A, MC68HC908JB12
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant
• Secondary Attributes: -
• Embedded: -
• Primary Attributes: -
• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

The communication between the sensor and the
MC68HC908QY4A is through a serial peripheral
interface (SPI) with clock input at the SCLK pin, the
data interface at the MISO and MOSI pins.
The receiver consists of:
• The MC68HC908JB12
• A button for identity device (ID) code setting
• A in-circuit programming (ICP) connector
• RF front-end circuitry
The functions of the MC68HC908JB12 are to handle
the USB transactions, capture and process data from
RF receiver front end. The processed data is converted
into USB report format and sent to the host.

The ID button is used to interrupt the MCU for a new
ID code detection. The MCU will search if there is any
ID code embedded in the RF data packet and store the
new ID in FLASH memory. There is a transistor wakeup
circuit connected at the IRQ pin and is controlled by
an I/O pin. The MCU will configure the wakeup circuit
before entering stop mode for power saving. The RC
components connected at the transistor base input will
be charged up, and eventually turn on the transistor
and pull low the IRQ to wakeup the MCU.
The ICP interface is connected at port A. The ICP is
used for future firmware updating through the Cyclone
Programming Tools.
