FlexMatrix™ Keyboard Encoder ICs

Standard for us, but customizable for you!
 FlexMatrix™ keyboard encoder ICs integrates very Flexible features such as macro keys, key controlled GPOs, PWM and IO backlit control, Fn key. Several types of macro keys are implemented to generate symbol ($, ), combination key (CTRL+ALT+DEL, SHIFT+F1), sequential key ("00", "Coke Cola"). Left Fn and Right Fn keys can select 4 matrix tables to map 4 different logic keys to one physical keys. Multiple level PWM/IO backlit control logic is embedded in to the ICs and you can build such complicated functioin without any programming. We provide standard FlexMatrix™ off-the-shelf keyboard encoder ICs, you provide your customers with custom keyboards.
