DESCRIPTION
The Z16M27 is a general-purpose PCMCIA adapter chip
used on the side of the interface. The Z16M27 contains
special circuitry for PCMCIA-to-ATA/IDE applications, but
easily configures to all types of memory and I/O mapped
peripheral hardware, supporting a wide variety of PC card
applications.
The Z16M27 can be used in a stand-alone configuration
without the use of a local processor by providing all of the
attribute memory, CCRs, range, and interrupt types through
a serial EEPROM. The serial EEPROM is read automati-

cally using an internal EEPROM sequencer. The Z16M27
can also be configured through a local processor for use
on intelligent controller systems.
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.,
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
