Z86017/Z16017 PCMCIA Interface Solution
Product Specification
General Description
Note:
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.
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.
