GENERAL DESCRIPTION

The Z86KXX Keyboard Controllers are full-featured members 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 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.
