Features: FPC1020A is a secondary development module for fingerprint recognition designed for single-chip microcomputer. It has small size, low power consumption, simple interface, high reliability, small fingerprint template (200 bytes), large-capacity fingerprint recognition (1000 fingerprint recognition response time is less than 1) Seconds, etc., can be easily embedded into the user system to form a fingerprint identification product that meets customer needs. In particular, the self-learning function is provided. In the process of fingerprint recognition, the newly extracted fingerprint feature value is successfully combined and the feature value is merged into the fingerprint database, so that the user can use it more effectively during use. The 1020A module communication interface is UART or USB. This module acts as a slave device, and the master device sends relevant commands to control it. The module has an adjustable security level function, read/write function of fingerprint feature data, and read/write function of fingerprint image. The recognition mode is 1:N recognition or 1:1 verification. Using capacitive area array semiconductor fingerprint sensor. The sensor has 256 grayscale pixel quality per pixel. Identify the neural network self-learning function after passing. Optimize the quality of wet finger acquisition in semiconductor sensors. Increase the intelligent repair processing of defective fingerprint images. Implementation and comparison of fingerprint data under minimum storage conditions: fingerprint template is 200 bytes. Specification: Sleep power consumption: 25uA Verification function: 1:N/ 1:1 communication method: UART 360 rotation recognition: support Security Level: 1-9, default level 5 Characteristic data: Upload/download function operating system: Fit for Windows Fingerprint identification capacity: 150 fingerprints , recognition time less than 1 second Technical Parameters: Sensor resolution: 500DPI Sensor pixel: 160*160 Processing speed: < 0.45 seconds Fingerprint extraction time: < 0.45 seconds False rate: 0.0001% 1:N comparison time: < 0.45 seconds ( 1000 pcs) Rejection rate: 0.001% stand-by current: <25μA (steady standby current) Communication Interface: UART, USB No flow control: Flow Control=NONE Dynamic current: <50mA Operating Voltage: 3V or 5V Operating temperature: 10°C-60°C Relative humidity: Fingerprint capacity: 150 pcs Serial communication parameters: No parity Parity= NONE, 1 stop bit Stop Bit = 1 Baud rate: 9600, 19200 (factory setting), 38400, 57600, 115200 ( bps ) Lead foot No. name name Functional description 1 VT In Finger detection power input, 3. 3V 2 T Out Finger detection signal output 3 V In Power positive input terminal, 3. 3V 4 TX Out Serial data output, TIL logic level 5 RX In Serial data input, TIL logic level 6 GND - Signal ground, internal and power ground connection Package List: 1 x Capacitive Fingerprint Recognition Module Note: 1. In the type column, m indicates input to the module and out outputs from the module. 2, The module needs 2 sets of power supply separately, one set is the module serial port power supply, one set is the induction power-on chip power supply, common ground. 1, 6 is the power supply of the sensor chip, it needs to be powered all the time; 3, 6 is the serial port power supply of the module. When the finger is close to the fingerprint window, pin 2 generates a high level. When the client MCU receives this level, it powers the module 3 and 6 through the module serial power control circuit (triode or MOS tube). 1、FPC1020A is a secondary development module for fingerprint recognition designed for single-chip microcomputer.
