ITON TECHNOLOGY LTD. Bluetooth 3.0 HID ModuleFigure 1: Block DiagramThe BT3GMD-B47P employs an integrated ARM CortexTM-M3 microprocessor corethat runs software from the Link Control layer up to the Host Controller Interface (HCI).Thebaseband portion of the BT3GMD-B47P performs all the time-critical functions requiredfor high-performance Bluetooth operations.The radio incorporates the complete receive and transmit paths, including PLL, VCO,LNA, PA, upconverter,downconverter, modulator, demodulator, and channel selectfiltering.The BT3GMD-B47P on-chip keyboard scanner is designed to autonomously samplekeys and store them into buffer registers without requiring host microcontrollerintervention. A state machine of three states(Idle, Scan, and Scan-End)controls thekeyscan block.The module has a SPI interface. The interface has a 16-byte transmit buffer and a16-byte receive buffer .To support more flexibility for user applications. The module actsas an SPI master device that supports 1.8V or 3.3V SPI slaves.

ITON TECHNOLOGY LTD. Bluetooth 3.0 HID ModuleSection 2: Supporting Documentions2.1 Reference SchematicThe most recent schematic , bill of material ,and layout file are availablefrom the ITON Technology Limit. Contact your ITON representative for details.2.2 Layout ConsiderationsThe BT3GMD-B47P module is placed at the location where the antenna isaway from the power supply(i.e.,BT1 Battery contacts)and any digital signaltraces. There should be no key matrix membrane under the antenna area andthe user’s hand should not be over the antenna area when the keyboard is in use.The antenna keep-out area which is 5mm around the parameter of the moduleregion is shown in the red dotted box. PCB material and signal traces should notbe placed within the antenna keep-out area to assure optimum antennaperformance.Figure 3: Keyboard PCB2.3 Electrical CharacteristicsTable 3: Maximum Electrical RatingTable 4 :Power supplyRating Symbol Value UnitDc supply voltage －1.4(Min)--3.8(Max) VVoltage on input or output pin －Vs s -0.3 to Vdd +0.3 VOperating ambient temperature range Topr 0 to +70 ℃Storage temperature range Tstg -40 to +125 ℃Rating Minimum Typical MaximumDc supply voltage 1.6V 2.8V 3.6V

Attention: Limited Modular Approval ‐this RF Module may not be sold to the generic public and requires professional installation. Due to the fact that this RF Module is not equipped with an own shielding, the end‐product incl. this RF Module has to show compliance to the FCC rules (15B/radiated emissions). (OEM)Integrator has to assure compliance of the entire end‐product incl. the integrated RF Module. Additional measurements (15B) and/ or equipment authorizations (e.g Verification) may need to be addressed depending on co‐location or simultaneous transmission issues if applicable. Integrator is reminded to assure that these installation instructions will not be made available to the end‐user of the final host device. With the low output power, this RF Module meets the FCC SAR exemption. The final host device, into which this RF Module is integrated "has to be labeled with an auxiliary lable stating the FCC ID of the RF ModuleThe RF Module is powered by DC ,the antenna is PCB antenna and the antenna gain is 2 dBi. This device complies with part15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2)this device must accept any interference received, including interference that may cause undesired operation. "should be placed also on the device or alternatively within a prominent location of the users manual Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.  , such as" Contains FCC ID: QTG-ZKMS
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC compliance requirement of the end product, which integrates this module. Due to missing shielding the module is strictly limited to integration by the Grantee himself or his dedicated OEM Integrator. The integration is strictly limited into following host platform(s) that are electrically identical incl. variations that are defined as Class I Permissive Change to the documented and certified samples under the control of the Grantee. Additional hosts and/or platforms can be added via Class II Permissive Change by the Grantee. -Bluetooth KeyboardThis RF Module will be exclusively integrated into battery power host devices under strict control of the Grantee.
