Stress greater than those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This is a stress rating only; operation of the device at any condition
above those indicated in the operational sections of these specifications is not implied. Exposure
to absolute maximum rating conditions for an extended period may affect device reliability.
DescriptionThe Z86L33/L43 Consumer Controller Processor (CCP™) 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 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
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.
