GENERAL DESCRIPTION

W83626F/W83626D is a transparent LPC-to-ISA bus conversion IC.

For the new generation Intel chipset Camino and Whitney, SiS Super South 960,
featuring LPC bus, there is no support for ISA bus and slots. However the demand of
ISA devices still exist. For such case, W83626F is the best companion solution for the
non-ISA chipset. Also the packages of W83626F had been chosen to be the most
economic solution for save the M/B board layout size and cost.

For the new generation chipset featuring LPC interface and support no ISA bus,
W83627HF (Winbond LPC I/O) together with the set of W83626F is the complete
solution.

SD[15:0]

122-1

119-1

75-71

69-67

OUT24 System Data. SD[15:0] provide the 16-bit data path for devices

residing on the ISA Bus. The W83626F tri-states SD[15:0] during
PCIRST#.

AEN

OUT24 Address Enable. AEN is asserted during DMA cycles. This signal

is also driven high during W83626F initiated refresh cycles. AEN is
driven low upon PCIRST#.

IOR#

OUT24 I/O Read. IOR# is the command to an ISA I/O slave device that the

slave may drive data on to the ISA data bus (SD[15:0]).

OUT24 I/O Write. IOW# is the command to an ISA I/O slave device that

the slave may latch data from the ISA data bus (SD[15:0]).

IOCHRDY

INt

I/O Channel Ready. Resources on the ISA Bus negate IOCHRDY
to indicate that additional time (wait states) is required to complete
the cycle.

SYSCLK

OUT24 ISA System Clock. SYSCLK is the reference clock for the ISA

bus. The SYSCLK is generated by dividing PCICLK by 3 or 4.

RSTDRV
