GENERAL DESCRIPTION

The Z86KXX Keyboard Controllers are full-featured mem-

bers of the Z8® MCU family offering a unique register-to-

register architecture that avoids accumulator bottlenecks

and is more code efficient than RISC processors.

For keyboard applications demanding powerful I/O capa-

bilities, 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 modi-

fications in the output drivers and clock circuitry of the de-

vice.
