2. GENERAL DESCRIPTION
MX25L25645G is 256Mb bits Serial NOR Flash memory, which is configured as 33,554,432 x 8 internally. When it
is in two or four I/O mode, the structure becomes 134,217,728 bits x 2 or 67,108,864 bits x 4.
MX25L25645G feature s a serial peripheral interface and software protocol allowing operation on a simple 3-wire
bus while it is in single I/O mode. The three bus signals are a clock input (SCLK), a serial data input (SI), and a
serial data output (SO). Serial access to the device is enabled by CS# input.
When it is in two I/O read mode, the SI pin and SO pin become SIO0 pin and SIO1 pin for address/dummy bits
input and data output. When it is in four I/O read mode, the SI pin, SO pin, WP# and RESET# pin (of the 8-pin
packages) become SIO0 pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.
The MX25L25645G MXSMIO?
(Serial Multi I/O) provides sequential read operation on the 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 byte basis, or page (256
bytes) basis, or word basis. Erase command is executed on 4K-byte sector, 32K-byte block, or 64K-byte block, or
whole chip basis.
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.
Advanced security features enhance the protection and security functions, please see security features section for
more details.
When the device is not in operation and CS# is high, it is put in standby mode.
The MX25L25645G utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after
100,000 program and erase cycles.
*Note: The pin of RESET#, RESET#/SIO3 or WP#/
SIO2 will remain internal pull up function while
this pin is not physically connected in system
configuration.
However, the internal pull up function will be
disabled if the system has physical connection
to RESET#, RESET#/SIO3 or WP#/SIO2 pin.
6. DATA PROTECTION
During power transition, there may be some false system level signals which result in inadvertent erasure or
programming. The device is designed to protect itself from these accidental write cycles.
The state machine will be reset as standby mode automatically during power up. In addition, the control register
architecture of the device constrains that the memory contents can only be changed after specific command
sequences have completed successfully.
In the following, there are several features to protect the system from the accidental write cycles during VCC powerup and power-down or from system noise.
? Valid command length checking: The command length will be checked whether it is at byte base and completed
on byte boundary.
? Write Enable (WREN) command: WREN command is required to set the Write Enable Latch bit (WEL) before
other command to change data.
? Deep Power Down Mode: By entering deep power down mode, the flash device also is under protected from
writing all commands except Release from deep power down mode command (RDP) and Read Electronic
Signature command (RES), and softreset command.
? Advanced Security Features: there are some protection and security features which protect content from
inadvertent write and hostile access
