DESCRIPTION
The Z8615 Keyboard Controller (KBC) is a member of the Z8® single-chip microcontroller family with 4 Kbytes of ROM. The device is housed in a 40-pin DIP and 44-pin PLCC package, and is manufactured in NMOS technology. The Z8615 KBC microcontroller offers fast execution, efficient use of memory, sophisticated interrupt, input/output bit-manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption.
   
The Z8615 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.
   
For applications which demand powerful I/O capabilities, the KBC provides 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.
