Hi-Speed USB peripheral controller
RESET_N
7
I
reset input (500
s); a LOW level produces an asynchronous
reset; connect to VCC for power-on reset (internal POR circuit)
When the RESET_N pin is LOW, ensure that the WAKEUP pin
does not go from LOW to HIGH; otherwise the device will enter
test mode.
TTL; 5 V tolerant
EOT
8
I
end-of-transfer input (programmable polarity); when not in use,
connect this pin to VCC(I/O) through a 10 k resistor
input pad; TTL; 5 V tolerant
DREQ
9
O
DMA request (programmable polarity) output; when not in use,
connect this pin to ground through a 10 k
resistor; see
TTL; 4 ns slew-rate control
DACK
10
I
DMA acknowledge input (programmable polarity); when not in
use, connect this pin to VCC(I/O) through a 10 k resistor; see
TTL; 5 V tolerant
DIOR
11
I
DMA read strobe input (programmable polarity); when not in
use, connect this pin to VCC(I/O) through a 10 k resistor; see
TTL; 5 V tolerant
DIOW
12
I
DMA write strobe input (programmable polarity); when not in
use, connect this pin to VCC(I/O) through a 10 k resistor; see
TTL; 5 V tolerant
DGND
13
-
digital ground
INT
14
O
interrupt output; programmable polarity (active HIGH or LOW)
and signaling (edge or level triggered)
CMOS output; 8 mA drive
CS_N
15
I
chip select input
input pad; TTL; 5 V tolerant
RD_N
16
I
read strobe input
input pad; TTL; 5 V tolerant
WR_N
17
I
write strobe input
input pad; TTL; 5 V tolerant
A0
18
I
bit 0 of the address bus
input pad; TTL; 5 V tolerant
A1
19
I
bit 1 of the address bus
input pad; TTL; 5 V tolerant
A2
20
I
bit 2 of the address bus
input pad; TTL; 5 V tolerant
21
-
supply voltage; used to supply voltage to the I/O pads; see
A3
22
I
bit 3 of the address bus
