GENERAL DESCRIPTION
The Z86E04/E08 One-Time-Programmable (OTP) microcontrollers are pin compatible to the masked ROM Z86C04/C08 devices. OTPs are designed to verify software and hardware functionality through quick pilot production for debugging and prototyping without committing to a masked ROM device. However, Zilog's OTP manufacturing capability allows high-volume production of these devices.
The Z86E04/08 are full-featured members of the Z8® microcontroller family offering a unique register-to-register architecture that avoids accumulator bottlenecks and is more code efficient than RISC processors.
The Z86E04/E08 are designed for use in a wide variety of embedded control applications such as keyboards, telephone answering machines, IR remotes, appliances, security systems, electronic games, and automotive modules.
For applications demanding powerful I/O capabilities, the Z86E04/E08 devices feature 14 pins dedicated to input and output. These lines are grouped into three ports, and are configurable under software control to provide I/O, timing, and status signals.
Two on-chip counter/timers, with a large number of user-selectable modes, are available to relieve the system of administering real-time tasks, such as counting/timing and I/O datacommunications.
The Z86E04/E08 have two on-board comparators with a common reference that implements analog functions such as A/D conversion.
Six different internal or external interrupt sources are maskable and prioritized in which a vectored address is provided for efficient interrupt sub-routine handling and multitasking functions.

The Z86E30/E31 are full-featured members of the Z8® microcontroller
family offering a unique register-to-register architecture that avoids
accumulator bottlenecks and is more code efficient than RISC processors.
The Z86E30/E31 are designed to be used in a wide variety of embedded
control applications, such as keyboards, telephone answering machines,
IR remotes, appliances, security systems, electronic games, and automotive
modules.
For applications demanding powerful I/O capabilities, the Z86E30/E31
devices feature 24 pins dedicated to input and output. These lines are
grouped into three ports, and are configurable under software control
to provide I/O, timing, and status signals.
Two on-chip counter/timers, with a large number of user-selectable modes,
are available to relieve the system of administering real-time tasks, such

that implement analog functions such as A/D conversion.
Six different internal or external interrupt sources are maskable and
prioritized in which a vectored address is provided for efficient interrupt
sub-routine handling and mulitasking functions.
By means of an expanded register file, the designer has access to three
additional system control registers which provide extra peripheral devices,
I/O ports, and register addresses. (See Functional Block Diagram).
