PIN DESCRIPTION
GENERAL DESCRIPTION
The MX25L8005 is a CMOS 8,388,608 bit serial Flash memory, which is configured as 1,048,576 x 8 internally. The
MX25L8005 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 MX25L8005 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 MX25L8005 utilize MXIC's proprietary memory cell, which reliably stores memory contents even after 100,000 program
and erase cycles.
