Z8602

The Z8602 Keyboard Controller (KBC™) 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 of Z8602  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 of Z8602 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 General- Purpose 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.
