E December 2007 Atrua Technologies Confidential & Proprietary Page 1 of 20 ATW300 Fingerprint Touch Sensor Family Data Sheet General Description The ATW300 family of fingerprint touch sensors (ATW3xx) is the sensor portion of the Atrua Wings™ touch processing system. The system consists of: Touch sensors – small, low cost and low power sensors that provide information on finger features and movement. Algorithms – fingerprint recognition, navigation and control functions that are highly precise and accurate and operate in a very CPU- and memory-efficient manner. The ATW3xx touch sensor creates partial images (frames) of the finger by sensing the ridges and valleys on the finger as it is moved or “swept” across its surface. This small Adaptive Capacitance™ sensor provides high performance and low power consumption through an integrated 124 x 8 sensing array of metal electrodes. Ridges and valleys on the finger yield varying capacitance values across the array, which are read to form a partial image of the fingerprint. Internal circuits within the sensor die convert the sensed data into a stream of digital data (a frame) that is presented to the host microprocessor via an 8-bit bidirectional bus interface, which is compatible with most microprocessors, or through a high-speed SPI interface. There are two key classes of algorithms that execute on the host processor and comprise the core functions of this fingerprint touch processing system: Fingerprint Authentication Control and Navigation Optimized for use in mobile devices, the low cost, small physical size and minimal power consumption of the ATW3xx touch sensor simplify its integration into mobile phones and other small mobile devices. The ATW3xx integrates the typically external over-current protection circuit to enable significant BOM cost savings and to further minimize the board area required for the total solution. Additionally, the ATW3xx has an integrated analog-to-digital converter to digitize the sensed data and an automatic gain control (AGC) function that provides high quality fingerprint images from all types of skin, dry to moist, in a wide range of climatic conditions, even cold and dry. In addition to the sensor’s low power requirements, the end system’s power consumption can be further minimized by utilizing one of the ATW3xx’s advanced finger detect modes. These modes are designed to analyze on-sensor the finger’s characteristics and wake the host CPU only after the sensor concludes that contact was made by an actual finger, not a foreign object. This reduces the need to unnecessarily wake the CPU subsystem, thus saving even more power. The ATW3xx touch sensor is fabricated in standard CMOS technology and is provided in a Green/RoHS compliant LGA package. The sensor surface is protected by a special abrasion and chemical-resistant coating to provide long life with high reliability. These algorithms operate on the data streamed from the sensor. Authentication extracts minutiae features used for fingerprint verification, and matches the minutiae pattern to the template for the user’s enrolled finger. The navigation/control algorithms analyze finger motions to provide control functions. 850-0003-001 Rev. E December 2007 Atrua Technologies Confidential & Proprietary Page 2 of 20 ATW300 Fingerprint Touch Sensor Family Data Sheet Conventions Unless otherwise noted, a positive logic (active High) convention is assumed throughout this document. A lowercase ‘n’ following a signal name (e.g., INTRn) indicates that the signal is active Low. The designation 0xNNNN indicates a hexadecimal number. The designation 0bNNNN indicates a binary number. Signal Descriptions Name D[7:0] Type Bi-directional Description 8-bit Mode: Data bus with CMOS inputs. These pins provide an 8-bit data path for read and write operations. The bus is in the high-impedance state when CSn or RDn is negated. SPI Mode: D7/MISO functions as the MISO (Master In Slave Out). Data is shifted out of the SPI slave and into the SPI master. D6/MOSI functions as the MOSI (Master Out Slave In). Data is shifted out of the SPI master and into the SPI slave. A0/SCK Input D5/SCK_INV selects the polarity of SCK. When SCK_INV is Low, data is shifted out of the MISO on the falling edge of SCK and the MOSI is sampled on the rising edge of SCK. When SCK_INV is High, data is shifted out of the MISO on the rising edge of SCK and the MOSI is sampled on the falling edge of SCK. 8-bit Mode: Address. CMOS input. When A0 is Low, the Index Address register (IDX_REG) is selected as the source/destination for read and write transactions. When A0 is High, the indexed register (see Functional Description) is selected as the source/destination for read and write transactions. SPI Mode: SPI Clock. CMOS input. When SCK_INV is Low, data is shifted out the MISO on the falling edge of SCK and the MOSI is sampled on the rising edge of SCK. When SCK_INV is High, data is shifted out the MISO on the rising edge of SCK and the MOSI is sampled on the falling edge of SCK. 850-0003-001 Rev. E December 2007 Atrua Technologies Confidential & Proprietary Page 3 of 20 ATW300 Fingerprint Touch Sensor Family Data Sheet CSn/SCSn Input 8-bit Mode: Chip Select, active Low. CMOS input. This input must be asserted to read data from or write data to the ATW3xx. When High, the data bus is in the high impedance state. SPI Mode: Slave Chip Select, active Low. CMOS input. RDn Input Drive SCSn Low to select the device as an SPI slave. Drive SCSn High to deselect the device, reset the SPI, and to place the MISO in the high impedance state. 8-bit Mode: Read Enable, active Low. CMOS input. This input must be asserted for read operations and negated for write operations. When High, data outputs from the device are disabled and the data bus pins are placed in the high impedance state. WRn Input SPI Mode: RDn must be driven Low. Drive both RDn and WRn Low to place the device into SPI mode. The device returns to 8-bit Mode if either RDn or WRn is driven High. 8-bit Mode: Write Enable, active Low. CMOS input. Controls writing of commands or data to the ATW3xx. A write operation takes place when WRn is asserted while CSn is Low and RDn is High. The data is latched on the rising edge of WRn.

Drive both RDn and WRn Low to place the device into SPI mode. The device returns to 8-bit Mode if either RDn or WRn is driven High. Interrupt Request, active Low. INTRn is asserted if interrupts are enabled and an interrupt event takes place. External Clock Input. The ATW3xx has an internal clock and does not require an external clock input. This input is for testing only and should be left unconnected for normal operation. Core Power. Core Ground. I/O Power. I/O Ground. ESD Ground. These pins are intended to provide a discharge path during an electrostatic discharge event. Connect these pins to chassis ground.

Please refer to the diagram below. The pin 1 orientation is marked by a single non-right-angled corner of the sensing region. The other three corners of the sensing region have right-angled corners. The pin 1 indicator allows the orientation of the sensor to be determined by microscope inspection and/or through automated optical inspection of the top surface of the sensor.

Refer to the Manufacturing Guidelines document (631-0002-002) for the latest and most complete guidelines and for additional details on sensor handling during manufacturing operations such as SMT and assembly. 1) 2) 3) 4) 5) 6) Do not allow the sensor’s exposed die surface to come in contact with any hard or metallic objects. If the sensors need to be manipulated by hand, operators should use anti-static finger cots and either a static dissipative rubber tipped vacuum wand (or pen) or static dissipative (conductive filament) plastic tipped tweezers. When using vacuum wands (or pens), ensure that the tip of the metal capillary does not extend beyond the rubber suction cup. When using tweezers, ensure the sensor die surface is not allowed to come in contact with the tweezers’ tips. Both tweezers tips and rubber cups should be placed on a regular replacement schedule to prevent wear-out damage. Do not stack sensor boards directly on top of each other. Use anti-static foam spacers to separate boards if stacking is absolutely necessary. If protective tape is used on the sensor surface, it should be electrically conductive/static dissipative and not leave adhesive residue, such as a Kapton film tape with silicone adhesive. When handling sensors and sensor sub-assemblies, operators must be properly grounded by one of the following: z A wrist strap connected to ground z A minimum of one heel ground with both feet on a static dissipative floor surface. When not being processed, sensors and sensor assemblies must be stored in static shielded boxes or antistatic or static dissipative plastic bags. 850-0003-001 Rev.
