Atmel AT77C101B
The AT77C101B is part of the Atmel FingerChip monolithic fingerprint sensor family for which no optics, no prism and no light source are required. The AT77C101B is a single-chip, high-performance, low-cost sensor based on temperature physical effects for fingerprint sensing. The AT77C101B has a linear shape, which captures a fingerprint image by sweeping the finger across the sensing area.| Part No. | AT77C101B |
