Part#: MX25U3232FM2I02
Part Category: Memory ICs

Manufacturer: Macronix International Co., Ltd.

Description: Flash, 4MX8, PDSO8

MX25U3232F is 32Mb bits Serial NOR Flash memory, which is configured as 4,194,304 x 8 internally. When it is
in two or four I/O mode, the structure becomes 16,777,216 bits x 2 or 8,388,608 bits x 4. MX25U3232F features 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 become SIO0 pin,
SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.
The MX25U3232F 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 refer to the security features section for more details.
When the device is not in operation and CS# is high, it will remain in standby mode.
The MX25U3232F utilizes Macronix’s proprietary memory cell, which reliably stores memory contents even after
100,000 program and erase cycles.
