2317 Rev 1.1 (17NOV04) AuthenTec Confidential Information 6

1. Introducing the EntréPad AES2501A Slide Sensor…

…, the latest, lowest cost fingerprint sensor IC for PC Applications. AuthenTec has adapted its

patented, award winning TruePrint Technology to read fingerprints while the finger is pulled

across the AES2501A's rectangular surface. In this manner, the fingerprint images are

acquired AND the sensor is substantially reduced in size.

The AES2501A combines silicon-based image slice capture with proprietary sensor control

and image segment matching algorithms to provide the best quality lowest cost biometric

authentication solution available.

1.1 TruePrint Technology is…

…AuthenTec’s unique patented fingerprint reading technology. During imaging, a small signal

is generated between the IC and the finger’s living tissue layer. 3072 individual sensing

elements in the slide sensor matrix form a planar antenna array that receives this signal,

creating a digital pattern that accurately reproduces the fingerprint’s underlying structure.

A powerful utility contained within TruePrint Technology™ is Dynamic Optimization™. This

tool analyzes each image, controlling up to 15 parameters real-time to optimize the fingerprint

image slices, regardless of unusual skin conditions or surface contamination. This functionality

is built right into the sensor hardware or you can perform these functions in software for total

control and upgrade-ability.

1.3 Conventions

For vectors (groups of bits), ordering will always be from MSB to LSB (e.g.

Pixel_Data[63:0] where bit 63 is the MSB and bit 0 is the LSB).

When vectors that span multiple bytes are transmitted, the lower byte (bits

[7:0]) is transmitted first. This applies to pixel data and the authentication

word returned after each imaging frame.

Numbers followed by a ‘b’ are shown in binary. Numbers followed by an

‘h’ are in hexadecimal.

1.4 Operational Description

The Sensor begins operation in the ‘idle’ state after a reset. In the idle

state, array power is turned off and clocking is disabled (except to support

interface activity). It is then necessary for the system SW to program the

sensor for the desired operation (Imaging or Navigation). After this setup,

the requested operation is enabled by setting the Op Enable bit (located in

mode checks for a finger present at a rate programmed by the Finger

Detect Rate setting. The default reset value sets the detect period to ~62

ms.

After finger detection, the sensor will begin the programmed operation and

will enter Imaging mode until the finger is removed. Once the finger is

removed, the sensor returns to the Low Power Finger Detect mode.

When no activity is detected on the system interface bus for approximately

200uS, power is reduced by disabling the internal clocks and the array

power is once again turned off.

Figure 1-1 Row Numbering

2317 Rev 1.1 (17NOV04) AuthenTec Confidential Information 8

The array consists of 192 columns of 16 pixels each. During imaging, the

columns are powered up and the signals from each of the 16

pixels/column are sampled, digitized and returned to the host computer

over the selected interface sequentially in order on a per-column basis.

The sensor has the capability to utilize only the center 128 columns during

imaging mode to facilitate higher finger sliding speeds. During fingerprint

enrollment, a 192 pixel wide template is created. Then, optionally, either a

192 pixel wide or 128 pixel wide verify can be performed. This mode is

entirely controlled via software using sensor register settings for start and

stop columns.

If the finger detect is not active when it is rechecked at the end of a scan,

the array is powered down and the sensor reverts back to checking for a

finger at the programmed detect rate.

AuthenTec has application notes to support the integration of the

AES2501A for all available interface options. Contact AuthenTec for

availability.

1.5 Navigation Using the AES2501A

The navigation use model is a button replacement system. The typical

Left / Right / Up / Down button functionality can be easily emulated on the

sensor by statically touching the sensor to indicate desired left or right

direction and by sliding the finger at normal finger speeds in the up or

down direction to indicate up or down.

When operations are enabled (via the OP ENABLE bit as described

previously) and Navigation mode is selected, the sensor will provide

constant, periodic indications of direction and finger presence by sending

a 2-byte message to the selected interface.

After NAV mode is enabled, the sensor takes 10 samples of the center

column approximately every 100 us. After producing an output message,

the sensor then enters a low power state for a programmable amount of

time, and then repeats the above sequence. Output generation rates are

programmable and range from 100 Hz down to 26 Hz.

*Warning

The AES2501A remains fully operational at temperatures that are high enough to be

uncomfortable for the user.

For reasons of safety and protection, AuthenTec reference designs include circuitry that

serves to manage the junction temperature by controlling the supply current. If the

hardware developer elects not to use the AuthenTec-provided control circuit design, it will

then be essential that an equivalent design be developed and implemented.
