HT6542B
Keyboard Controller with PS/2
Pin Assignment
40 Pin DIP package
44 Pin PLCC package
General Description
The HT6542B is a keyboard controller devel-
oped by Holtek with a 4-bit microprocessor. It is
pin-to-pin compatible with Intel 8042 keyboard
controller used in IBM PC’s. PC manufacturers
need not modify any printed wiring layout
when using the HT6542B in lieu of the Intel
8042 based keyboard controller. Furthermore,
the HT6542B can support a system clock speed
of up to 12MHz. The HT6542B can detect the
motherboard type automatically, therefore it
can be employed on both of AT and PS/2 moth-
erboard.
