... Minimum Voltage may undershoot to –2V during transition and for less than 20ns during transitions. SUMMARY DESCRIPTION The M29F040B Mbit (512Kb x8) non-volatile memory that can be read, erased and repro- grammed. These operations can be performed us- ing a single 5V supply. On power-up the memory defaults to its Read mode where it can be read in the same way as a ROM or EPROM ...

... M29F040B SIGNAL DESCRIPTIONS See Figure 1, Logic Diagram, and Table 1, Signal Names, for a brief overview of the signals connect this device. Address Inputs (A0-A18). The Address Inputs select the cells in the memory array to access dur- ing Bus Read operations. During Bus Write opera- tions they control the commands sent to the Command Interface of the internal state machine ...

... M29F040B Block Erase Command. The Block Erase com- mand can be used to erase a list of one or more blocks. Six Bus Write operations are required to select the first block in the list. Each additional block in the list can be selected by repeating the sixth Bus Write operation using the address of the additional block. The Block Erase operation starts the Program/Erase Controller about 50µ ...
