Data Sheet
One bus cycle is eight clock periods.
Address bits above the most significant bit of each density can be V IL or V IH .
4 KByte Sector-Erase addresses: use A MS -A 12, remaining addresses are don’t care but must be set either at V IL or V IH.
32 KByte Block-Erase addresses: use A MS -A 15, remaining addresses are don’t care but must be set either at V IL or V IH.
To continue programming to the next sequential address location, enter the 8-bit command, ADH, followed by 2 bytes of
data to be programmed. Data Byte 0 will be programmed into the initial address [A 23 -A 1 ] with A 0 =0, Data Byte 1 will be
programmed into the
initial address [A 23 -A 1 ] with A 0 = 1.
6. The Read-Status-Register is continuous with ongoing clock cycles until terminated by a low to high transition on CE#.
7. Either EWSR or WREN followed by WRSR will write to the Status register. The EWSR-WRSR sequence provides back-
ward compatibility to the SST25VF/LF series. The WREN-WRSR sequence is recommended for new designs.
8. Manufacturer’s ID is read with A 0 =0, and Device ID is read with A 0 =1. All other address bits are 00H. The Manufac-
turer’s ID and device ID output stream is continuous until terminated by a low-to-high transition on CE#.
