The Z86E61/E63 microcontrollers are members of the Z8^®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 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/output 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 highvolume
applications or where code flexibility is required.
