THE INTELLIGENT APPROACH TO INTELLECTUAL PROPERTY
BUS INTERFACE
M82365SL
PC CARD INTERFACE CONTROLLER
OVERVIEW
The M82365SL considerably simplifies the notebook system designer’s task by providing an industry standard
solution to the problem of interfacing one or more PC Card sockets to a Notebook PC that uses an
external ISA bus (8 or 16-bit).
It provides an open standard system interface for PC
Cards at the hardware and data interchange level which in
turn ensures that PC Card compatibility can be realised
across manufacturers of PC Cards as well as between
systems provided by the notebook PC vendors.
Up to eight PC Card sockets can be supported by
using a cascade of up to four M82356SLs. Each socket can
be independently configured to support either memory or
I/O cards. Memory and I/O windowing facilities are
provided between the ISA bus and the PC Cards.
The support for the two sockets is clearly divided into
two areas in the design, allowing the M82365SL to be
readily adapted to a single socket system if required.
The M82365SL is software compatible with the
Intel 82365SL.

PC CARD CONFIGURATION
The PC Card can be set up either through a configuration
(CONFIG.SYS) driver or through an extension to the BIOS
(System Sockets Services). The need for jumpers has been
eliminated by providing Address Mapping Support for the
PC Card Memory together with Address Windowing Support
for I/O Space.
POWER MANAGEMENT
The M82365SL offers a range of power saving options include
socket power control, insertion/removal capability, power
saving with Windows inactivity, NCS controlled Chip Power
Down, together with further controls for 3.3V Suspend with
Modem Ring Resume Detection. Applications requiring ultra
low power consumption can use one of the two additional
signals offered by the M82365SL to gate SYSCLK. (The other
extra signal is for use during scan test.)
SIGNAL DESCRIPTION
The M82365SL has 122 external signals: 55 inputs and 67 outputs.
