MBF110  
Solid-State Fingerprint Sensor  
Packages  
Overview  
The Fujitsu MBF110 Solid-State Fingerprint Sensor is a direct  
contact, fingerprint acquisition device. It is a high performance,  
low power, low cost, capacitive sensor with an integrated two-  
dimensional array of metal electrodes in the sensing array. Each  
metal electrode acts as one plate of a capacitor and the contacting  
finger acts as the second plate.A passivation layer on the device  
surface forms the dielectric between these two plates. Ridges and  
valleys on the finger yield varying capacitor values across the array,  
which is read to form an image of the fingerprint.  
80-pin SOP (VSPA)  
80-pinTSOP (LQFP)  
A block diagram of the MBF110 is shown in Figure 1.The  
MBF110 has an integrated 8-bit flash analog-to-digital converter  
to digitize the output of the sensor array.The fingerprint image is  
transmitted on an 8-bit bi-directional bus interface compatible  
with most microprocessors.  
The MBF110 is manufactured in standard CMOS technology and  
is available in an 80-pin,VSPA 80/1 and LQFP 80/1.The 300 ×  
300 sensor array has a 50 µm pitch and yields a 500-dpi image.The  
sensor surface is protected by a patented, ultra-hard, abrasion and  
chemical resistant coating.  
For SETCUR resistor differences between the MBF110 see the Pin  
Information table.
