Z86C90 - Zilog.

Z86C90 ROMLESS CMOS Z8 8-BIT MICROCONTROLLER

The Z86C90/C89 CCP™ (Consumer Controller Processor) introduces a new level of sophistication to single-chip architecture. The Z86C90/C89 are ROMless members of the Z8 single-chip microcontroller family with 236 bytes of general purpose RAM. The only difference that exists between the Z86C89 and the Z86C90 is that the on-chip oscillator of the Z86C89 can acce.

Features

that are useful in many industrial, automotive, computer peripherals, and advanced scientific applications. The CCP applications demand powerful I/O capabilities. The Z86C90/C89 fulfills this with 32 pins dedicated to input and output. These lines are grouped into four ports. Each port consists of eight lines, and is configurable under software control to provide timing, status signals, parallel I/O with or without handshake, and an address/data bus for interfacing external memory. There are four basic address spaces available to support this wide range of configurations: Program Memory, Regis.
