GENERAL DESCRIPTION
The MX25L4005 is a CMOS 4,194,304 bit serial Flash
memory, which is configured as 524,288 x 8 internally. The
MX25L4005 feature a serial peripheral interface and soft-
ware 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 MX25L4005 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 byte /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 MX25L4005 utilize MXIC's proprietary memory cell,
which reliably stores memory contents even after 100,000
program and erase cycles.
