GENERAL DESCRIPTION
The Z86C60/65 microcontrollers introduce a new level of sophistication to single-chip architecture. The Z86C65 is a member of the Z8 single-chip microcontroller family with 32 Kbytes of ROM and 256 bytes of RAM. The Z86C60 is identical, except that it only has 16 Kbytes of ROM. The Z86C60/65 are housed in a 28-pin DIP package, and manufactured in CMOS technology. The Z86C96 ROMless Z8 will support the Z86C60/65. 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 Z86C60/65 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 Z86C60/65 fulfills this with 22 pins dedicated to input and output. These lines are grouped into four ports. 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 Z86C60/65 offers two on-chip counter/timers with a large number of user selectable modes.
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). Power connections follow conventional descriptions below: Connection Power Ground Circuit VCC GND Device VDD VSS
