Solid-State Fingerprint Sensor
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 twodimensional 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.
Packages
A block diagram of the MBF110 is shown in Figure 1. The MBF110 has an integrated 8-bit flash analog-to-digital converter The MBF110 is manufactured in standard CMOS technology and to digitize the output of the sensor array. The fingerprint image is is available in an 80-pin, VSPA 80/1 and LQFP 80/1. The 300 x transmitted on an 8-bit bi-directional bus interface compatible 300 sensor array has a 50 m pitch and yields a 500-dpi image.

Chip Operation
The sensor array is composed of 300 rows and 300 columns of sensor plates. Associated with each column are two sample-and-hold circuits. A fingerprint image is sensed or captured one row at a time. This"row capture"occurs in two phases. In the first phase, the sensor plates of the selected row are pre-charged to the VDD voltage. During this pre-charge period, an internal signal enables the first set of sample-and-hold circuits to store the pre-charged plate voltages of the row. In the second phase, the row of sensor plates is discharged with a current source. The rate at which a cell is discharged is proportional to the"discharge current."After a period of time (referred to as the "discharge time"), an internal signal enables the second set of sample-and-hold circuits to store the final plate voltages. The difference between the pre-charged and discharged plate voltages is a

measure of the capacitance of a sensor cell. After the row capture, the cells within the row are ready to be digitized. The sensitivity of the chip is adjusted by changing the discharge current and discharge time. The nominal value of the current source is controlled by an external resistor connected between the SETCUR pin and ground. The current source is controlled from the Discharge Current Register (DCR). The discharge time is controlled by the Discharge Time Register (DTR). The sensor array is a row-oriented device. Images are read out one row at a time. The High-Order Row Address Register (RAH) and the Low-Order Row Address Register (RAL) must be programmed to 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. After the discharge cycle, the outputs of the row elements will be stored in analog sample and hold circuits.

Solid-State Fingerprint Sensor
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.

A/D Converter
The integrated 8-bit flash A/D converter is a buffered device. 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.

Manufacturing Considerations
CAUTION: DO NOT USE ANY METAL PICKUP TOOLS WHICH WOULD CONTACT THE SENSOR DEVICE SURFACE WITHOUT PROTECTIVE LID INSTALLED * Surface Mount reflow temperature: Recommended Max Temp 220C Max reflow spike* 240C
* Avoid any high pressure spray directly to the sensor device surface. * Use standard handling practices for ESD sensitive devices. * Refer to Fujitsu PCB Assembly for Biometric Sensor Guidelines.
Array Pixel Specifications:
Specification Max Failed Pixels Max Failed Rows Max Failed Columns Notes:
1) Failing rows or columns that fall on rows (0-4) or (295-299) or columns (0-4) or (295-299) are allowed to pass for the STD product due to packaging overlap at the edge of the sensor array. Failed rows or columns at the extreme edge of the array do not affect the quality of the acquired fingerprint image.
