GENERAL DESCRIPTION
PS014401-1001
The Z86E61/E63 microcontrollers are members of the Z8® single-chip microcon-
troller family with 16K/32 Kbytes of EPROM and 236 bytes of general-purpose
RAM. Offered in 40-pin DIP, 44-pin PLCC or 44-Pin LQFP package styles, these
devices 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/out-
put bit manipulation 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. There are three basic address spaces available to support this configu-
ration: Program Memory, Data Memory, and 236 general-purpose registers.
To unburden the system from coping with real-time tasks such as counting/timing
and serial data communication, the Z86E61/E63 offers two on-chip counter/timers
with a large number of user selectable modes (Figure 1).
