12 / 51 page 10 Am29PDS322D 23569A5 December 4, 2006 D A TA SH EE T If the device is deselected during erasure or program- ming, the device draws active current until the operation is completed. I CC3 in the DC Characteristics table represents the standby current specification. Automatic Sleep Mode The automatic sleep mode minimizes Flash device en- ergy consumption. The device automatically enables this mode when addresses remain stable for t ACC + 30 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# control signals. Standard ad- dress access timings provide new data when ad- dresses are changed. While in sleep mode, output data is latched and always available to the system. Automatic sleep mode current is drawn when CE# = V SS ± 0.3 V and all inputs are held at VCC ± 0.3 V. If CE# and RESET# voltages are not held within these tolerances, the automatic sleep mode current will be greater. I CC5 in the DC Characteristics table represents the automatic sleep mode current specification. RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of re- setting the device to reading array data. When the RE- SET# pin is driven low for at least a period of t RP, the device immediately ter minates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state ma- chine to reading array data. The operation that was in- terrupted should be reinitiated once the device is ready to accept another command sequence, to en- sure data integrity. Current is reduced for the duration of the RESET# pulse. When RESET# is held at V SS ± 0.3 V, the device draws CMOS standby current (I CC3). If RESET# is held at V IL but not within VSS ± 0.3 V, the standby current will be greater. The RESET# pin may be tied to the system reset cir- cuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firm- ware from the Flash memory. If RESET# is asserted during a program or erase op- eration, the RY/BY# pin remains a “0” (busy) until the internal reset operation is complete, which requires a time of t READY (during Embedded Algorithms). The sys- tem 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 t READY (not during Embedded Algo- rithms). The system can read data t RH after the RE- SET# pin returns to V IH. Refer to the AC Characteristics tables for RESET# pa- rameters and to Figure 17 for the timing diagram. Output Disable Mode When the OE# input is at V IH, output from the device is disabled. The output pins are placed in the high impedance state. |
