circuits. A fingerprint image is sensed or captured one row at a time. cells within the row are ready to be digitized. Discharge Time Register (DTR). select a row to be captured. Writing to RAL initiates a row capture. The capture time is a function of the external clock and the DTR. stored in analog sample and hold circuits.

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 .

RAL (A3-A0 Address 0000) Write Only Low Order Row Address Register This register and bit 0 of RAH form the 9-bit Row Address Register that selects the row to be captured. The 9-bit Row Address Register selects a row address from 0 through 299. Writing the RAL starts a row capture. Only RAL has to be written if RAH doesn’t change, otherwise RAH has to be written before RAL.

CAL (A3-A0 Address 0010) Read/Write Low Order Column Address Register CAL is a read/write register . Writing to this address writes to the low-order 8 bits of the 9-bit Column Address Register . The 9-bit Column Address Register selects a column from 0 through 299. Writing to CAL causes the analog-to-digital (A/D) converter to begin digitizing its input. The input of the A/D converter is selected by bits 7 and 6 of the CAH register . The user should wait until the row capture is completed before writing to the CAL. Reading from this address returns the output of the A/D converter . After writing to CAL, the user should wait until A/D conversion completes before reading the A/D converter .

Each write to CAL causes: 1) the result of the previous conversion to be latched and made readable at CAL, and 2) the A/D converter to start digitizing its current input. Consequently , it takes 301 writes to CAL in order to digitize the 300 cells of a row . Specifications* *All specifications in this document are preliminary and subject to change.
