The differentiating factor between these devices is the availability of ROM, and package options. For the 40 and 44-pin devices the use of external memory enables these Z8 microcontrollers to be used where code flexibility is required. Zilog’s CMOS microcontrollers offers fast executing, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and inDS96LV00800 ternal key-scan pull-up resistors. The Z86LXX product line offers easy hardware/software system expansion cost-effective and low power consumption. The Z86LXX architecture is based on Zilog's 8-bit microcontroller core with an Expanded Register File to allow access to register mapped peripherals, I/O circuits, and powerful counter/timer circuitry. The CCP offers a flexible I/O scheme, an efficient register and address space structure, and a number of ancillary features that are useful in many PRELIMINARY 1 Z86L88/81/86/87/89/73 IR/Low-Voltage Microcontroller GENERAL DESCRIPTION (Continued) consumer, automotive, computer peripheral, and battery operated hand-held applications. There are four basic address spaces available to support a wide range of configurations: Program Memory, Register File, Expanded Register File, and External Memory. The register file is composed of 256 bytes of RAM. It includes four I/O port registers, 16 control and status registers and the rest are General Purpose registers. The Expanded Register File consists of two additional register groups (F and D). External Memory is not available on 28pin versions. To unburden the program from coping with such real-time problems as generating complex waveforms or receiving and demodulating complex waveform/pulses, the Z86LXX family offers a new intelligent counter/timer architecture with 8-bit and 16-bit counter/timers (Figure 1). Also included are a large number of user-selectable modes, and two on-board comparators to process analog signals with separate reference voltages (Figure 2). 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).
