analog ground
RPU
2
A
connect to the external pull-up resistor for pin DP; must be
connected to 3.3 V via a 1.5 kΩ resistor
DP
3
A
USB D+ line connection (analog)
DM
4
A
USB D− line connection (analog)
AGND
5
-
analog ground
RREF
6
A
connect to the external bias resistor; must be connected to
ground via a 12.0 kΩ ± 1 % resistor
RESET_N 7
I
reset input (500 µs); a LOW level produces an asynchronous
reset; connect to VCC for the power-on reset (internal POR
circuit)
TTL; 5 V tolerant
EOT
8
I
End-of-transfer input (programmable polarity); used in DMA
slave mode only; when not in use, connect this pin to VCC(I/O)
through a 10 kΩ 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 kΩ resistor; see
Table 54 and Table 55
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 kΩ resistor;
see Table 54 and Table 55
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 kΩ resistor; see
Table 54 and Table 55
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 kΩ resistor; see
Table 54 and Table 55
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
