USB interface device with parallel bus
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/ data
bus. Permanently tied LOW for separate address/ data bus
configuration.
Chip Select (Active LOW).
Device is in 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 present on chip, so pin can be tied HIGH to V
GoodLink LED indicator (Active LOW)
Crystal Connection 1 (6 MHz).
Crystal Connection 2 (6 MHz). If external clock signal, instead
of crystal, is connected to XTAL1, then XTAL2 should be
floated.
Voltage supply (4.0 − 5.5 V).
To operate the IC at 3.3 V, supply 3.3 V to both V
pins.
USB D− data line.
USB D+ data line.
