**F87000 Multi-Mode Peripheral Chip 11/23/93
***Info:
The F87000 Multi-Mode Peripheral Chip is a companion to the F8680A
PC/CHIP single-chip PC. By strapping pins to select the desired mode,
the F87000 device becomes one of four integrated peripheral chips that
extend the functionality of PC/CHIP.
Chips and Technologies, Inc. has designed the F87000 chip specifically
for use with the F8680A microchip to accommodate portable computing
devices and embedded control applications where integration,
conservation of board space, and power consumption are critical.
In PCMCIA card implementations, card buffering and isolation is
recommended for design robustness, especially in rugged use enviro-
nments. The buffering ensures that the PCMCIA card receives a strong
clean signal, while the isolation provides both the protection for
"hot card insertion" and is hardwired for turning off power to a card.
Hardware isolation, supported with Power Management SuperState code,
minimizes the system’s power consumption. PCMCIA card slots that are
not properly buffered and isolated run a high risk of a system crash/
failure if the cards are inserted/removed while the slot is powered.
The PC/CHIP F87000 is designed to be used in four modes.
o Mode 1 ---- Single PCMCIA card buffering support provides:
• 20-bit address buffer.
• 16-bit bidirectional data buffer.
• Buffering for five control signals.
o Modes 2 and 3 ---- Dual PCMCIA card buffering support provides:
• Individual address buffering (64MB each).
• Individual data bus buffering.
• Two OR gates.
o Mode 4 ---- Multifunctional mode provides:
• Keyboard circuitry interfacing to a 16 x 8 keyboard matrix.
• Clock divider conversion of 14.31818MHz to 1.8432MHz output
(divide by 7.77).
• Parallel printer port.
• IDE interface.
• 7-bit configuration ports plus external select for port
expansion.

***Features:
o Fully static design substantially reduces power consumption when
compared to discrete TTL designs, allowing direct battery drive.
o 3.3V or 5V operation provides flexibility for system design and
allows dynamic 3.3/5V switching of system voltage to further
reduce power consumption.
o Each F8700 device can be strapped to configure one of three
buffer modes or a multi-function mode, reducing parts inventory
requirements.
o High integration means each F8700 mode replaces at least seven
discrete TTL devices.
o Full isolation of PCMCIA memory and I/O cards is supported to
allow safe insertion and removal of cards, both "hot" and "cold."
o PCMCIA buffer modes are completely PCMCIA 2.0-compatible.
o For single PCMCIA card support, Mode 1 buffers 20 address lines
and 5 control lines. Because of the quiet bus design of PC/CHIPm
the upper address lines can be connected directly to the PCMCIA
card slot in a single card system for full 64MB support.
o For dual PCMCIA card support, Modes 2 and 3 together buffer all
necessary address and control lines for independent 64MB support
of each card.
o Between PCMCIA cycles, the F87000 sets PCMCIA buses and control
lines to a low-power state to consume only a fraction of the power
used in a standard TTL buffer design.
o Multi-function mode (Mode 4) provides keyboard scanning, a
parallel interface, and IDE interface, a configuration latch, and
a 1.8MHz UART clock generation circuit.
o Keyboard scan interface in the multi-function mode requires only a
single external resister pack and provides an interrupt to the
system on key depression. The interface can be used instead as
general-purpose 16-bit output and 8-bit input ports.
o Parallel interface in the multi-functional mode allows high-speed,
PS/2-compatible bidirectional communication with other systems.
o Configuration latch can be used to control seven external devices
plus the UART clock divider. An additional decode line accommo-
dates an external latch for eight more device control lines.
