General Description
The Z86017/Z16017 (ZX6017) are general-purpose PCMCIA adapter
chips used on the card side of the interface. For increased versatility,
“mirror image” bond-out versions, the Z86M17 and Z16M17, are also
available. These chips are easily configured to allow access to all types of
memory or I/O-mapping peripherals, such as Ethernet controllers,
Universal Asynchronous Receiver/Transmitters (UART), modems,
rotating disk memory, and so on. The ZX6017 can be used in a stand-
alone configuration without the use of a local processor when all
necessary data for Attribute Memory, Card Configuration Registers
(CCR), Memory/I/O maps, and so on, are being provided by a local serial
EEPROM. The serial EEPROM is read automatically using an internal
EEPROM sequencer. The ZX6017 can also be configured by a local
microprocessor, when one is being used on the card.
Throughout this document, references to the ZX6017 device applies
equally to the Z86017 and Z16017, unless otherwise specified.
Note: All Signals with an overline ( ) are active Low, that is, B/W
(WORD is active Low); B/W (BYTE is active Low, only).
Power connections follow conventional descriptions below:

The ZX6017 can be programmed by one of two ways: an external 256
byte serial EEPROM can be connected to the serial port interface, or a
microprocessor can be connected to this port to provide a higher level of
control. Figure 1 depicts the functional block diagram for the ZX6017.
