GENERAL DESCRIPTION

The Z86KXX Keyboard Controllers are full-featured mem­bers of the Z8

®

MCU family offering a unique register-to­register architecture that avoids accumulator bottlenecks
and is more code efficient than RISC processors.

For keyboard applications demanding powerful I/O capa­bilities, the Z86KXX provides 32 pins dedicated to input
and output for row, column, clock, data, and LEDs.

The on-chip counter/timer is available to relieve the system
of administering real-time tasks.

Five different internal or external interrupt sources are
maskable and prioritized in which a vectored address is
provided for efficient interrupt subroutine handling and
multitasking functions.

The Z86K15 achieves low EMI by means of several modi­fications in the output drivers and clock circuitry of the de­vice.

ABSOLUTE MAXIMUM RATINGS

Stresses greater than those listed under Absolute Maxi­mum Ratings may cause permanent damage to the de­vice. This is a stress rating only; operation of the device at
any condition above those indicated in the operational sec­tions of these specifications is not implied. Exposure to ab­solute maximum rating conditions for extended periods
may affect device reliability.

STANDARD TEST CONDITIONS

The characteristics listed here apply for standard test con­ditions as noted. All voltages are referenced to GND. Pos­itive current flows into the referenced pin (Figure 5).
