Read More…The E2424 64 Key Encoder allows up to 64 normally open keyswitches in a 8x8 matrix to be encoded without external parts. This module simplifies the software overhead of the host microcontroller and reduces the I/O pins needed from 16 to one.
Keys are fully debounced with no false outputs regardless of any other combination of keys pressed. Keys are encoded on the make of the key with a response time of ~50msec due to a high speed scan of the keyswitch matrix and a unique debounce algorithm.
Outputs include a parallel 6 bit port, a 57.6Kbaud serial port, and an interrupt signal making interfacing easy. Power is +2.7V to +5.2V.
