A29L400A Series
CMOS standby current (ICC4 ). If RESET is held at VIL but not
within VSS ± 0.3V, the standby current will be greater.
The RESET pin may be tied to the system reset circuitry. A
system reset would thus also reset the Flash memory,
enabling the system to read the boot-up firmware from the
Flash memory.
If RESET is asserted during a program or erase operation,
the RY/ BY pin remains a “0” (busy) until the internal reset
operation is complete, which requires a time tREADY (during
Embedded Algorithms). The system can thus monitor
RY/ BY to determine whether the reset operation is
complete. If RESET is asserted when a program or erase
operation is not executing (RY/ BY pin is “1”), the reset
operation is completed within a time of tREADY (not during
Embedded Algorithms). The system can read data tRH after
the RESET pin return to VIH.
Refer to the AC Characteristics tables for RESET
parameters and diagram.
