Z86C63/64

CMOS Z8®

32K ROM MICROCONTROLLER

GENERAL DESCRIPTION

The Z86C63/64 microcontroller introduces a new level of sophistication to single-chip architecture. The Z86C63/64 is a member of the Z8 single-chip microcontroller family with 32 Kbytes of ROM and 256 bytes of RAM.

The Z86C63 is housed in a 40-pin DIP, and a 44-pin PLCC package, and is manufactured in CMOS technology. The ROMless pin option is available on the 44-pin version only. The Z86C64 is housed in a 64-pin DIP, and a 68-pin PLCC. Both versions of the Z86C64 have the ROMless pin option, which allows both external memory and preprogrammed ROM, enabling this Z8 microcontroller to be used in highvolume applications or where code flexibility is required. The Z86C96 ROMless Z8 will support the Z86C63/64.

Zilog’s CMOS microcontroller offers fast execution, more efficient use of memory, more sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption.

The Z86C63/64 architecture is characterized by Zilog’s 8-bit microcontroller core. The device 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 which demand powerful I/O capabilities, the Z86C63 fulfills this with 32 pins dedicated to input and output. These lines are grouped into four ports with eight lines each. The Z86C64 has 52 pins for input and output, and these lines are grouped into six, 8-bit ports and one 4-bit port. 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.

There are three basic address spaces available to support this wide range of configurations: Program Memory, Data Memory, and 236 General-Purpose Registers.

To unburden the program from coping with the real-time problems such as counting/timing and serial data communication, the Z86C63/64 offers two on-chip counter/timers with a large number of user selectable modes, and an asynchronous receiver/transmitter (UART) (see Block Diagrams).

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).
