GENERAL DESCRIPTION
The Z86319 is a member of the Z8 family of CMOS microcontrollers architecture to be used in mouse applications. These devices offer on-board pull-up and pull-down resistors, a trip-point buffer to accommodate opto-transistor outputs, and high drive ports capable of up to 10 mA current sinking per pin (3 pins maximum).
