SK5103 FlexMatrix Medical Keyboard Controller
●DESCRIPTION
■The SK5103 is a USB keyboard designed for medical applications and other complex industrial applications with a user-programmable keyboard matrix, USB controlled GPOs, PWMs. The IC can be programmed to any keyboard with four matrix tables for FN and NUMLOCK (or RFN) cases, so the IC is the best choice for custom keyboard solution but with an off-the-shelf IC.
■The SK5103 scans and encodes an 8-row by 18-column matrix. The key press events are translated to keyboard and mouse report. The encoder gets matrix information from on-chip flash matrix table. Sprintek provides Windows® application FlexMatrix Editor and Programmer software to edit, download and upload the matrix table.
■The SK5103 scans 9 AB rotary encoder inputs then reports the encoders’ rotation events as an 8-bit counter. The SK5103 deploys Sprintek encoder debounce algorithm to work with any mechanical encoders reliably. The SK5103 samples 16 channel analog inputs and reports the 8-bit absolute values to PC after a change.
■The SK5103 needn’t install special software device driver at PC side to support GPOs, PWMs, AB rotary encoders and analog sliders.
