Page 3 I Introduction DC 3.6V-6.0V UART(TTL logical Power Interface level)/ USB 1.1 Working current Typical: 100mA Matching Mode 1:1 and 1:N Peak: 150mA Baud rate (9600*N)bps, Character file size 256 bytes N=1～12 (default N=6） Image acquiring time <0.5s Template size 512 bytes Storage capacity 120/ 375/ 880 Security level...
Page 4 II Main Parameters III Hardware Interface Exterior Interface R303A (All in one) Connecting with PC (P1/P2 on board) Serial Communication(P1) When the FP module communicates with user device, definition of J1 is as follows: Name Type Function Description Pin Nmuber Power input Data output.
Page 5 Hardware connection Via serial interface, the Module may communicate with MCU of 3.3V or 5V power: TD (pin 2 of P1) connects with RXD (receiving pin of MCU), RD (pin 3 of P1) connects with TXD (transferring pin of MCU). Should the upper computer (PC) be in RS-232 mode, please add level converting circuit, like MAX232, between the Module and PC.
Page 6 Logic 1 =3.3V －0.3 Maximum input voltage Imax IV System Resources To address demands of different customer, Module system provides abundant resources at user’s use. Notepad The system sets aside a 512-bytes memory (16 pages* 32 bytes) for user’s notepad, where data requiring power-off protection can be stored.
Page 7 System Confiuration Parameter To facilitate user’s developing, Module opens part system parameters for use. And the basic instructions are SetSysPara & ReadSysPara. Both instructions take Parameter Number as parameter. When upper computer sends command to modify parameter, Module first responses with original configurations, then performs the parameter modification and writes configuration record into Flash.
Page 8 The new modified password is stored in Flash and remains at power off. Module address Each module has an identifying address. When communicating with upper computer, each instruction/data is transferred in data package form, which contains the address item. Module system only responds to data package whose address item value is the same with its identifying address.

Page 10 VI Module Instruction System R303A series provide 23 instructions. Through combination of different instructions, application program may realize muti finger authentication functions. All commands/data are transferred in package format. Refer to 5.1 for the detailed information of package.
