MX25L512C
The self-timed Sector Erase Cycle time (tSE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tSE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP1, BP0 bits, the Sector Erase (SE) instruction will not be executed on the page.
(9) Block Erase (BE)
The Block Erase (BE) instruction is for erasing the data of the chosen block to be "1". A Write Enable (WREN) in-
struction must execute to set the Write Enable Latch (WEL) bit before sending the Block Erase (BE). Any address
of the block (see table 3) is a valid address for Block Erase (BE) instruction. The CS# must go high exactly at the
byte boundary (the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not
executed.
The sequence of issuing BE instruction is: CS# goes low → sending BE instruction code→ 3-byte address on SI →
CS# goes high. (see Figure 20)
The self-timed Block Erase Cycle time (tBE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tBE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP1, BP0 bits, the Block Erase (BE) instruction will not be executed on the page.
(10) Chip Erase (CE)
The Chip Erase (CE) instruction is for erasing the data of the whole chip to be "1". A Write Enable (WREN) instruc-
tion must execute to set the Write Enable Latch (WEL) bit before sending the Chip Erase (CE). Any address of the
sector (see table 3) is a valid address for Chip Erase (CE) instruction. The CS# must go high exactly at the byte
boundary( the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not ex-
ecuted.
The sequence of issuing CE instruction is: CS# goes low→ sending CE instruction code→ CS# goes high. (see
Figure 20)
The self-timed Chip Erase Cycle time (tCE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Chip Erase cycle is in progress. The WIP sets 1 during the tCE
timing, and sets 0 when Chip Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the chip
is protected by BP1, BP0 bits, the Chip Erase (CE) instruction will not be executed. It will be only executed when
BP1, BP0 all set to "0".
(11) Page Program (PP)
The Page Program (PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction
must execute to set the Write Enable Latch (WEL) bit before sending the Page Program (PP). If the eight least sig-
nificant address bits (A7-A0) are not all 0, all transmitted data which goes beyond the end of the current page are
programmed from the start address if the same page (from the address whose 8 least significant address bits (A7-
A0) are all 0). The CS# must keep during the whole Page Program cycle. The CS# must go high exactly at the
byte boundary( the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not
executed. If more than 256 bytes are sent to the device, the data of the last 256-byte is programmed at the request
page and previous data will be disregarded. If less than 256 bytes are sent to the device, the data is programmed
at the request address of the page without effect on other address of the same page.
The sequence of issuing PP instruction is: CS# goes low→ sending PP instruction code→ 3-byte address on SI→
