Description
chip select signal assertion indicates the ISP1760 being accessed;
active LOW
input, 3.3 V tolerant
read enable; active LOW
input, 3.3 V tolerant
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
not connected
host controller interrupt signal
output pad, 4 mA drive, 3.3 V tolerant
not connected
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
host controller DMA request acknowledgment; when not in use,
connect to V
input, 3.3 V tolerant
connect to V
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
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
pull up to V
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 ISP1760
are not toggling and are in their inactive states.
analog ground
