GENERAL DESCRIPTION
The Z86C61/62/96 microcontroller is a member of the Z8 single-chip microcontroller family with 16 Kbytes of ROM and 256 bytes of RAM. The Z86C96 is ROMless. The Z86C61 is offered in 40-pin DIP and 44-pin PLCC style packages, however, the ROMless pin option is available on the 44-pin version only. The Z86C62/96 is offered in 64pin DIP and 68-pin PLCC style packages. A ROMless pin option enables these MCUs to address both external memory and preprogrammed ROM, making them wellsuited for high-volume applications or where code flexibility is required. With 16 Kbytes of ROM and 256 bytes of general-purpose RAM, these low-cost, low power consumption CMOS Z86C61/62/96 MCUs offer fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion. The Z86C61/62/96 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 Z86C61 fulfills this with 32 pins dedicated to input and output. These lines are grouped into four ports with eight lines each. The Z86C62/96 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.

GENERAL DESCRIPTION (Continued)
There are three basic address spaces available to support this configuration: Program Memory, Data Memory, and 236 General-Purpose Registers. To unburden the program from coping with the real-time tasks, such as counting/timing and serial data communication, the Z86C61/62/96 offers two on-chip counter/timers with a large number of user selectable modes, and an on-board UART (Figures 1, 2, and 3).
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
