GENERAL DESCRIPTION
ZiLOG's Z8® MCU single-chip family now includes the Z86C34/C35/C36/C44/C45/C46 product line, featuring enhanced wake-up circuitry, programmable Watch-Dog Timers (WDT), and low-noise/EMI options. Each of the new enhancements to the Z8 offer a more efficient, cost-effective design and provide the user with increased design flexibility over the standard Z8 microcontroller core. The low-power consumption CMOS microcontroller offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion. The Z8 subfamily features an Expanded Register File (ERF) to allow access to register-mapped peripheral and I/O circuits. Four basic address spaces are available to support this wide range of configurations: Program Memory, Register File, Data Memory, and ERF. The Register File is composed of 236/237 bytes of general-purpose registers, four I/O port registers, and 15 control and status registers. The ERF consists of twelve control registers. For applications demanding powerful I/O capabilities, the Z86C34/C35/C36 offers 24 pins, and the Z86C44/C45/C46 offers 32 pins dedicated to input and output. These lines are

GENERAL DESCRIPTION (Continued)
configurable under software control to provide timing, status signals, parallel I/O with or without handshake, and address/data bus for interfacing external memory. To unburden the system from coping with real-time tasks such as counting/timing and data communication, the Z8 offer two on-chip counter/timers with a large number of user-selectable modes. With ROM/ROMless selectivity, the Z86C44/C45/C46 provide both external memory and preprogrammed ROM, which enables this Z8® MCU to be used in high-volume applications, or where code flexibility is required.
Note: All signals with an overline are active Low. For example, B/W, for which WORD is active Low, and B/W, for which BYTE is active Low.
