Domestic Fingerprint Chip Developed Based On ARM Cortex -M3 Single -Chip Machine -P1032BF1

Core component of intelligent fingerprint locks:Motherboard, Clutch, fingerprint collector, password technology,microprocessor（CPU), Smart emergency key.As a fingerprint lock, the important thing is the fingerprint chip.Fingerprint locks are safe products produced by precision combinations of electronic components and mechanical parts.The essence of fingerprint locks is nothing more than three aspects: safety, convenience, and fashion.

Domestic fingerprint chip launched by Gongcai Electronic Agent Mountains -P1032BF1 is aARM  Cortex-M3Single -chip machine, Special for Wi-Fi /BluetoothDesigned by communication control; can be applied to smart locks; support large program code and own large -scaleEmbeddedSRAM, can also be used for generalMCUapplication.

P1032BF1 is wet sensitiveComponent; Wet sensitive levels are 3 levels, supporting 3.3V to 5V power supply; QFN32-5X5mm packaging; embedded POR, LVD, WDG, 32.768kHz oscillator for system locking and RTC, 1 to 30MHz clock input system lockRing ring, internal 48MHz factory cut RC.

P1032BF1 is a CMOS device.The floating level on the input signal causes the equipment to run unstable and the current consumption is abnormal.Pull or pull downresistanceIt should be appropriately used for input or two -way pins.
