write enable; active LOW
input, 3.3 V tolerant
digital ground
to indicate the presence of a minimum 3.3 V on pins 6 and 7 (open-drain); connect
to V
output pad, push-pull open-drain, 8 mA output drive, 5 V tolerant
peripheral controller interrupt signal
output 4 mA drive, 3.3 V tolerant
host controller interrupt signal
output 4 mA drive, 3.3 V tolerant
DMA controller request for the peripheral controller
output pad 4 mA drive, 3.3 V tolerant
DMA controller request for the host controller
output pad 4 mA drive, 3.3 V tolerant
digital supply voltage; 1.65 V to 3.6 V; connect a 100 nF decoupling capacitor; see
Section 7.8
host controller DMA request acknowledgment; when not in use, connect to V
through a 10 k pull-up resistor
input, 3.3 V tolerant
peripheral controller DMA request acknowledgment; when not in use, connect to
V
input, 3.3 V tolerant
core power output (1.8 V); internal 1.8 V for the digital core; used for decoupling;
connect a 100 nF capacitor; for details on additional capacitor placement, see
Section 7.8
host controller suspend and wake-up; 3-state suspend output (active LOW) and
wake-up input circuits are connected together
connect to V
output pad, open-drain, 4 mA output drive, 3.3 V tolerant
peripheral controller suspend and wake-up; 3-state suspend output (active LOW)
and wake-up input circuits are connected together
connect to V
output pad, open-drain, 4 mA output drive, 3.3 V tolerant
core ground
external power-up reset; active LOW; when reset is asserted, it is expected that bus
signals are idle, that is, not toggling
input, 3.3 V tolerant
Remark: During reset, ensure that all the input pins to the SAF1761 are not
toggling and are in their inactive states.
