X76F041
PIN DESCRIPTION
Serial Data Input/Output (SDA)
SDA is a true three state serial data input/output pin.
During a read cycle, data is shifted out on this pin.
During a write cycle, data is shifted in on this pin. In all
other cases this pin is in a high impedance state.
Serial Clock (SCL)
The Serial Clock controls the serial bus timing for data
input and output.
Chip Select (CS)
When CS is HIGH, the X76F041 is deselected and the
SDA pin is at high impedance and unless an internal
write operation is underway the X76F041 will be in the
standby power mode. CS LOW enables the X76F041,
placing it in the active power mode.
Reset (RST)
RST is a device reset pin. When RST is pulsed HIGH
while CS is LOW the X76F041 will output 32 bits of
fixed data which conforms to the ISO standard for
“synchronous response to reset”. CS must remain
LOW and the part must not be in a write cycle for the
response to reset to occur. If at any time during the
response to reset CS goes HIGH, the response to
reset will be aborted and the part will return to the
standby mode.
