CUSTOMER PROCUREMENT SPECIFICATION
Z8602
KEYBOARD CONTROLLER (KBCTM) NMOS Z8(R) 8-BIT MCU
GENERAL DESCRIPTION
The Z8602 Keyboard Controller (KBC TM) introduces a new level of sophistication to single-chip architecture. The Z8602 is a member of the Z8 single-chip microcontroller family with 2 Kbytes of ROM. The Z8602 KBC is housed in a 40-lead DIP, and is manufactured in NMOS technology. Zilog's microcontroller offers fast execution, more efficient use of memory, more sophisticated interrupt, input/output bit-manipulation capabilities, and easy hardware/ software system expansion along with low cost and low power consumption. The KBC architecture is characterized by a flexible I/O scheme, an efficient register, I/O, and a number of ancillary features that are useful in many industrial and advanced scientific applications. The device applications demand powerful I/O capabilities. The KBC fulfills this with 32-pins dedicated to input and output. These lines are grouped into four ports, each port consists of 8 lines, and are configurable under software control to provide timing, status signals, and serial or parallel I/O ports. The Z8602 offers low EMI emission achieved by means of several modifications in the output drivers and clock circuitry of the device. There are two basic address spaces available to support this wide range of configurations: Program Memory and 124 GeneralPurpose Registers. The KBC offers two on-chip counter/timers with a large number of user selectable modes. This unburdens the program from coping with real-time problems such as counting/timing.
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
