Solid-State Fingerprint Sensor

Fujitsu Microelectronics, Inc.
After the row capture is completed, the High-Order Column Address
Register (CAH) and Low-Order Column Address Register (CAL)
must be programmed to select an element within the captured row to
be digitized. Writing to CAL causes the analog-to-digital (A/D)
converter to digitize the difference between the outputs of the two
sample-and-holds of the selected column cell. The output of the A/D
converter is accessed by reading the CAL register.
Rows can be accessed in any order; however, the selected row must be
captured before the column cells are read. The column cells within a
row can be accessed in any order.
Special Features
There are two programmable open-drain outputs that can be used
for driving LEDs.
The CLKOUT pin can be enabled to output a square-wave clock of
the same frequency as the oscillator clock. CLKOUT can be used to
drive external circuitry. When ENCLK is high, the clock signal is
present at the CLKOUT pin. When ENCLK is low or unconnected,
the CLKOUT output is held low.
