Manufacturer:UTC Description:Word Program Operation The SST39VF160Q/VF160 are programmed on a word- by-word basis. The Program operation consists of three steps. The first step is the three-byte-load sequence for Software Data Protection. The second step is to load word address and word data. During the word Program opera- tion, the addresses are latched on the falling edge of either CE# or WE#, whichever occurs last. The data is latched on the rising edge of either CE# or WE#, whichever occurs first. The third step is the internal Program operation which is initiated after the rising edge of the fourth WE# or CE#, whichever occurs first. The Program operation, once initi- ated, will be completed within 10 µs. See Figures 4 and 5 for WE# and CE# controlled Program operation timing diagrams and Figure 15 for flowcharts. During the Pro- gram operation, the only valid reads are Data# Polling and Toggle Bit. During the internal Program operation, the host is free to perform additional tasks. Any commands issued during the internal Program operation are ignored. |
