GENERAL DESCRIPTION
Z86C47 ROM
CMOS Z8® 8-BIT
MICROCONTROLLER
The Z86C47 Digital Television Controller (DTC) introduces
a new level of sophistication to single-chip architecture.
The Z86C47 is a member of the Z8® single-chip
microcontroller family with 16 Kbytes of ROM and 236
bytes of RAM. The device is housed in a 64-pin DIP
package, and is CMOS compatible. The part features
ROMs for program storage and character generation. The
Z86C47 microcontroller may be used in prototyping, low
volume applications or where code development is re-
quired. Zilog’s DTC offers fast execution, efficient use of
memory, sophisticated interrupts, input/output bit manipu-
lation capabilities, and easy hardware/software system
expansion along with low cost and low power consump-
tion. The device provides an ideal performance and reli-
ability solution for consumer and industrial television appli-
cations.
The Z86C47 architecture utilizes Zilog’s advanced
Superintegration™ design methodology. The device has
an 8-bit internal data path controlled by a Z8 microcontroller,
On-Screen Display (OSD) logic circuits/Pulse Width Modu-
lators (PWM). On-chip peripherals include five register/
memory mapped I/O ports (Ports 2, 3, 4, 5, and 6), Interrupt
control logic (1 software, 2 external and 3 internal inter-
rupts) and a standby mode recovery input port (Port 3, pin
P30).
The OSD control circuits support eight rows by 20 columns
for 128 kinds of characters. The character color is speci-
fied by row. One of the eight rows is assigned to show two
kinds of colors for bar type displays such as volume
control. The OSD is capable of displaying high resolution
(11 x 15 dot pattern) characters.
DTC applications demand powerful I/O capabilities. The
Z86C47 fulfills this with 35 I/O pins dedicated to input and
output. These lines are grouped into five ports, and are
configurable under software control to provide timing,
status signals, parallel I/O and an address/data bus for
interfacing to external memory.
There are three basic address spaces available to support
this wide range of configurations: Program Memory, Reg-
ister File and Data Memory. The Data Memory address
space contains a number of control registers for the
PWMs, OSD, and I/O Ports 4, 5, and 6. Specifically, there
are 13 PWM and eight OSD control registers mapped into
the external memory address space. Three I/O registers
for Ports 4, 5, and 6 reside in data memory space as well.
The Register File is composed of 236 bytes of general
purpose register, two I/O Port registers and 15 control and
status registers.
To unburden the program from coping with the real-time
problems such as counting/timing and data communica-
tion, the DTC’s offer two on-chip counter/timers with a large
number of user selectable modes (see block diagram).
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.,
B//W (WORD is active Low); /B/W (BYTE is active Low, only).

A 14-bit PWM port provides enough voltage resolution for
a voltage synthesizer tuning system. Seven 6-bit PWM
ports are used for controlling audio signal level. Five 8-bit
PWM ports are used to vary picture levels.
