GENERAL DESCRIPTION
The Z86E15 microcontroller (MCU) is a member of the sin-
gle-chip Z8
MCU family with 4 KB of EPROM and 188
bytes of general-purpose RAM.
The Z86E15 is a pin-compatible, One-Time-Programma-
ble (OTP) version of the Z86K15 Keyboard Controller.
Zilog’s CMOS-microcontroller offers fast execution, effi-
cient use of memory, sophisticated interrupts, input/output
bit manipulation capabilities.
To unburden the program from coping with real-time prob-
lems such as counting/timing, the Z86E15 offers an on-
chip counter/timer with a large number of user-selectable
modes.
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 Z86E15 achieves low EMI by means of several modi-
fications in the output drivers and clock circuitry of the de-
vice.
