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 standalone 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.
