GENERAL DESCRIPTION
The Z86E61/E63 microcontrollers are members of the Z8
廬
single-chip microcontroller family with 16K/32 Kbytes of
EPROM and 236 bytes of general-purpose RAM. Offered
in 40-pin DIP or 44-pin PLCC package styles, these de-
vices are pin-compatible EPROM versions of the Z86C61/
63. The ROMless pin option is available on the 44-pin
versions only.
With 4 Kbytes of ROM and 236 bytes of general-purpose
RAM, the Z86E61/E63 offers fast execution, efficient use of
memory, sophisticated interrupts, input/output bit manipu-
lation capabilities, and easy hardware/software system
expansion.
For applications demanding powerful I/O capabilities, the
Z86E61/E63 offers 32 pins dedicated to input and output.
These lines are grouped into four ports. Each port consists
of eight lines, and is configurable under software control to
provide timing, status signals, serial or parallel
I/O with or without handshake, and an address/data bus
for interfacing external memory.
The Z86E61/E63 can address both external memory and
preprogrammed ROM, making it well suited for high-
volume applications or where code flexibility is required.
