Z86E64

The Z86E64 is a member of the Z8 single-chip microcontroller family. The Z86E64 can address both external memory
and pre-programmed ROM, which enables this Z8 MCU^TM to be used in high-volume applications where code flexibility is required.

The Z86E64 is a pin compatible, One-Time-Programmable (OTP) version of the Z86C64. The Z86E64 contains 32 KB of EPROM memory in place of the 32 KB of ROM on the Z86C64.

There are three basic address spaces available to support this wide range of configuration: Program Memory, Data Memory, and 236 general-purpose registers.

The Z86E64 offers a flexible I/O scheme, an efficient register and address space structure, multiplexed capabilities between address/data, I/O, and a number of ancillary features that are useful in many industrial and advanced scientific applications.

For applications demanding powerful I/O capabilities, the Z86E64's dedicated input and output lines are grouped into six ports. Each port consists of eight lines, except port 6, which has four lines. Each port 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 Z86E64 offers two on-chip counter/timers with a large number of user-selectable modes, and an Universal Asynchronous Receiver/Transmitter (UART). See figure 1 for- Functional Block description.
