The only differentiating factor between the E72/73 versions is the availability of RAM and ROM. This EPROM microcontroller family of OTP controllers also offers the use of external memory, which enables this Z8 microcontroller to be used where code flexibility is required. ZiLOG's CMOS microcontrollers offer fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and easy hardware/software system expansion along with cost-effective and low power consumption. The Z86E7X 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 Z8 offers a flexible I/O scheme, an efficient register and address space structure, and a number of ancillary features that are useful in many consumer, automotive, computer peripheral, and batteryoperated hand-held applications. Z8 applications demand powerful I/O capabilities. The Z86E7X family fulfills this with three package options in which the E72/73 versions provide 31 pins of dedicated input and output. These lines are grouped into four ports. Each port consists of eight lines (Port 3 has seven lines of I/O and one Pref comparator input) and is configurable under software control to provide timing, status signals, parallel I/O with or without handshake, and an address/data bus for interfacing external memory. There are five basic address spaces available to support a wide range of configurations: program memory, register file, Expanded Register File, Extended Data RAM, and external memory. The register file is composed of 256 bytes of RAM. It includes 4 I/O port registers, 16 control and status registers, and the rest are general-purpose registers. The Extended Data RAM adds 512 (E72) of usable general-purpose registers. The Expanded Register File consists of two additional register groups (F and D). To unburden the program from coping with such real-time problems as generating complex waveforms or receiving and demodulating complex waveform/pulses, the Z86E7X family offers a new intelligent counter/timer architecture with 8-bit and 16bit 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 19 on page 34). Note: PS008704-0507 All signals with a preceding front slash, “/”, are active Low. For example, B//W (WORD is active Low); /B/W (BYTE is active Low, only). Z86E72/73 OTP Microcontroller 3 HI 16 Lo 16 8 8 16-Bit T16 1 2 4 8 Timer 16 16 8 SCLK Clock Divider 8 TC16L TC16H And/Or Logic HI8 LO8 8 Input Edge Detect Circuit Glitch Filter 8 8-Bit T8 Timer 8 8 8 TC8H TC8L Figure 1.

Absolute Maximum Ratings Symbol Description Min Max Units VMAX Supply Voltage (*) –0.3 +7.0 TSTG Storage Temperature –65° +150° C TA Oper. Ambient Temperature † V C Notes: * Voltage on all pins with respect to GND. † See “Ordering Information” on page 97. Stresses greater than those listed under Absolute Maximum Ratings might cause permanent damage to the device. This rating 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 might affect device reliability.
