CXD4000R  
Fingerprint Verification System LSI  
Description  
120 pin LQFP (Plastic)  
The CXD4000R is an IC that inputs the signal from  
a Sony fingerprint sensor and performs fingerprint  
verification.  
This chip integrates a CPU, A/D converter, DRAM,  
USB controller and other circuits.  
Features  
• Combination with a Sony fingerprint sensor and a  
flash memory realizes a fingerprint verification  
system with a 3-chip configuration  
• 16-bit microcomputer SPC970  
Applications  
• USB controller (conforms to Rev 1.1)  
• Fingerprint verification units (stand-alone)  
• Cellular phones  
• Personal computers  
Fingerprint Verification Block  
• Adoption of Sony's original verification algorithm  
also provides excellent results for blurred and  
deformed fingerprints  
• False rejection ratio: 1% or less, false acceptance  
ratio: 0.1% or less (with 2 trials)  
• Verification time per finger: approximately 40ms  
(Clock frequency: 48MHz, excluding fingerprint  
image loading time)
