The module provides one UART interface output port for connecting to a main board of device. l 160x160 pixels l Build-in ADC for digitizing image l UART interface l Data encryption l Short read out time The operation processes of AS-108M’s sensor (HF- l Cost effective sensor 108) are as follows, a fingerprint image captured by l High sensing capability pixel array, delivery fingerprint ridge/valley signals to l Single power supply A/D converter and digital processor, then to the serial peripheral interface for data-reading. Because MCU has been already installed with fingerprint algorithm, the user can use MCU SOC commands through UART [APPLICATIONS] interface for operating module, such as fingerprint l Door lock enrollment, fingerprint match etc. l Security device l Access control system Rev.1.1 www.adh-tech.com.tw 2 / 11 sales@adh-tech.com.tw AS-108M Fingerprint Sensor Module Datasheet Table of Contents 1 Electrical Characteristics ......................................................................... 4 1.1 1.2 Maximum rating .................................................................................... 4 Operation condition ............................................................................... 4 2 Specification .............................................................................................. 5 3 Mechanical Specification ......................................................................... 6 3.1 3.2 3.3 3.4 4 SDK Guide ............................................................................................... 10 4.1 4.2 4.3 4.4 5 Connector Pin Description .................................................................... 6 Connector Information .......................................................................... 7 Package size......................................................................................... 8 Outline Reference ................................................................................. 9 UART setting....................................................................................... 10 Initial time ............................................................................................ 10 Command protocol.............................................................................. 10 Hardware connection .......................................................................... 10 Revision history ...................................................................................... 11 Rev.1.1 www.adh-tech.com.tw 3 / 11 sales@adh-tech.com.tw AS-108M Fingerprint Sensor Module Datasheet 1 Electrical Characteristics 1.1 Maximum rating Symbol VDD Parameter Conditions Supply voltage Value Unit 4 V TA Operating temperature -40 to 80 ℃ ST Storage temperature -40 to 125 ℃ 1.2 Operation condition Symbol Parameter Conditions Min.
