NAND FLASH MEMORY - MX25L1005 (U158)

13.1
14.1.
MX25L1005 is a CMOS 1,048,576 bit serial Flash memory, which is configured as 131,072 x 8 internally.
The MX25L1005 feature a serial peripheral interface and software protocol allowing operation on a simple
3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output
(SO). SPI access to the device is enabled by CS# input. The MX25L1005 provide sequential read operation
on whole chip. After program/erase command is issued, auto program/ erase algorithms which program/
erase and verify the specified page or sector/block locations will be executed. Program command is
executed on page (256 bytes) basis, and erase command is executes on chip or sector(4K-bytes) or
block(64K-bytes). To provide user with ease of interface, a status register is included to indicate the status
of the chip. The status read command can be issued to detect completion status of a program or erase
operation via WIP bit. When the device is not in operation and CS# is high, it is put in standby mode and
draws less than 10uA DC current. The MX25L1005 utilize MXIC's proprietary memory cell, which reliably
stores memory contents even after 100,000 program and erase cycles.
