Z86E23

Z86E23 CPS DC-4060-06 CUSTOMER PROCUREMENT SPECIFICATION Z86E23 CMOS Z8® OTP MICROCONTROLLER GENERAL DESCRIPTION The Z86E23 microcontroller introduces the next level of sophistication to single-chip architecture. The Z86E23 is a member of the Z8 single-chip microcontroller family with 8 Kbytes of EPROM and 236 bytes of general-purpose RAM. The Z86E23 is a pin compatible, One-Time-Programmable (OTP) version of the Z8614 and Z8602 Keyboard Controller (KBC). Zilog’s CMOS microcontroller offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption. The Z86E23 architecture is based on Zilog’s 8-bit microcontroller core. The device offers a flexible I/O scheme, an efficient register and address space structure, and a number of ancillary features that are useful in many industrial and advanced scientific applications. There are two basic address spaces available to support this wide range of configurations: program memory and 236 general-purpose registers. To unburden the program from coping with real-time problems such as counting/timing, the Z86E23 offers two on-chip counter/timers with a large number of user selectable modes (Block Diagram). 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: C...
