GENERAL DESCRIPTION
The Z86L33/L43 Consumer Controller Processor (CCPTM) is a member of Zilog's Z8® single-chip microcontroller family with enhanced wake-up circuitry, programmable Watch-Dog Timers (WDT), and low-noise/EMI options. These enhancements result in a more efficient, costeffective design and provide the user with increased design flexibility over the standard Z8 microcontroller core. This 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 Z86L33/L43 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, External Data Memory (L43), and ERF. The Register File is composed of 236 bytes of general-purpose registers, four I/O port registers, and 15 control and status registers. The ERF consists of three control registers (Banks 0,D, and F) For applications demanding powerful I/O capabilities, the Z86L33 provides 24 pins, and the Z86L43 provides 32 pins dedicated to input and output. These lines are configurable CP96LVO1501 (6/96) u n d e r 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 Z86L33/L43 offers two on-chip counter/timers with a large number of user-selectable modes. With ROM/ROMless selectivity, the Z86L43 provides both external memory and pre-programmed ROM, which enables this Z8 microcontroller to be used in high-volume applications, or where code flexibility is required.
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
