Description
bit 0 of bidirectional data; slew-rate controlled
bit 1 of bidirectional data; slew-rate controlled
bit 2 of bidirectional data; slew-rate controlled
bit 3 of bidirectional data; slew-rate controlled
ground
bit 4 of bidirectional data; slew-rate controlled
bit 5 of bidirectional data; slew-rate controlled
bit 6 of bidirectional data; slew-rate controlled
bit 7 of bidirectional data; slew-rate controlled
Address Latch Enable: The falling edge is used to close the latch of
the address information in a multiplexed address or data bus.
Permanently tied to LOW for separate address or data bus
configuration.
chip select (active LOW)
When the CS_N pin is LOW, ensure that the RESET_N pin is in
inactive state; otherwise, the device will enter test mode.
device is in the suspend state
programmable output clock (slew-rate controlled)
interrupt (active LOW)
read strobe (active LOW)
write strobe (active LOW).
DMA request
DMA acknowledge (active LOW)
end of DMA transfer (active LOW); double up as V
EOT_N is only valid when asserted together with DMACK_N and
either RD_N or WR_N.
reset (active LOW and asynchronous); built-in power-on reset circuit
is present on-chip, so the pin can be tied HIGH to V
When the RESET_N pin is LOW, ensure that the CS_N pin is in
inactive state; otherwise, the device will enter test mode.
GoodLink LED indicator (active LOW)
crystal connection 1 (6 MHz)
crystal connection 2 (6 MHz); if the external clock signal, instead of
the crystal, is connected to XTAL1, then XTAL2 should be floated
voltage supply (4.0 V to 5.5 V)
To operate the IC at 3.3 V, supply 3.3 V to both the V
pins.
