SK5100/SK5101 FlexMatrix Keyboard Controller Data Sheet
●DESCRIPTION
■The SK5100/SK5101 is a keyboard encoder with a user-programmable keyboard matrix and an interface that can be configured to a USB or PS/2 interface. The IC can be programmed to any keyboard with four matrix tables for FN and NUMLOCK cases, so the IC is the best choice for custom keyboard solution but with an off-the-shelf IC.
■SK5101 is the pin-to-pin compatible low cost version of SK5100. The only differences are operation temperature range and pin36. The SK5100/SK5101 scans and encodes an 8-row by 20-column matrix. 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 SK5100/SK5101 provides an external PS/2 port that supports hot plug and hot swap of PS/2 mouse and keyboard devices. If the IC is configured to PS/2 interface, then the IC external PS/2 port supports only keyboards. If the IC is configured to USB interface, then the IC external PS/2 port supports keyboards, mice including wheel mice.
