Door Keypads and Readers

Your repository for building intrusion HMI keypad design resources


A door keypad and reader is used to verify a user’s credentials, granting or denying them access into a room or building. Authentication can come from keypads, card readers, biometrics, or a hybrid of multiple credentials. Texas Instruments keypad and reader end equipment solutions aim to help you reduce time to market while bringing innovative features to your design.

TI Designs demonstrates alternative ways to implement keypads apart from traditional mechanical buttons. TI Designs show robust keypad solutions, including capacitive buttons using MSP430 FRAM MCUs or capacitive-to-digital converters. TI Designs also demonstrate touch on metal buttons using TIs inductive sensing devices. TI has integrated motor driver products for driving the solenoid locking mechanism. Efficient wired and wireless communication protocols are also demonstrated in TI Designs. Some examples are the use of Wi-Fi bridges to retrofit wired communication to a wireless one. Other TI Designs show a 10/100Mbps Ethernet PHY Brick and an IR remote control method.
