Z8615 - Zilog.

Z8615 NMOSZ8 8-BITMCU KEYBOARD CONTROLLER

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 capabili.

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. The Z8615 KBC offers low EMI emission which is achieved by means of several modifications in the output drivers and clock circuitry of the device. There are two basic address spaces which are available to support this wide range .
