Revision 1.4
PC87200 PCI to ISA Bridge
1.0 General DescriptionThe PC87200 Enhanced Integrated PCI-to-ISA bridge
works withan LPC chipsetto provide ISA slot support.Itis complementto the National Semiconductor PC8736x
Super I/O family.
2.0 Features
2.1 General Functionally compatible with Intel 82380AB 5.0 V tolerant PCI and ISA interfaces Slave mode serialized IRQ supportfor both quiet and
continuous modes PC/PCI DMA support 32-bit address decode for the 1MB BIOS ROM Supports ISA bus mastering 160-pin PQFP package
2.2 PCI-to-ISA Bridge PCI 2.1 compliant 33 MHz bus Supports PCI initiator-to-ISA and ISA master-to-PCI
cycle translations Subtractiveagentfor unclaimed transactions (see the
PROHIBIT signal description for exceptions) Parallel to Serial IRQ conversion including
IRQ3,4,5,6,7,9,10,11,12,14,15 Supports 4 ISA slots directly without buffering Programmable ISA clock (8.33 to 11 MHz) Slow slew rate on edges
2.3 "PROHIBIT" functional support Disables PCI bus subtractive decoding when PRO-
HIBIT is asserted
