Macronix MX25L3233F MXSMIO® NOR Flash Memory

Macronix MX25L3233F MXSMIO® (Serial Multi I/O) NOR Flash Memory is 3V, 32M-Bit Flash Memory configured internally as 4,194,304 x 8. When it is in four I/O mode, the structure becomes 8,388,608 bits x 4. When it is in two I/O mode, the structure becomes 16,777,216 bits x 2. MX25L3233F features a serial peripheral interface and a software protocol that allow operation on a simple 3-wire bus in single I/O mode. The three bus signals are the clock input (SCLK), the serial data input (SI), and the serial data output (SO). The CS# input enables serial access to the device.

The MX25L3233F, MXSMIO (Serial Multi I/O) flash memory, provides sequential read operations across the entire chip and multi-I/O features. When it is in quad I/O mode, the SI, SO, WP#, and HOLD# pins become SIO0, SIO1, SIO2, and SIO3, respectively, for address/dummy bit input and data Input/Output.

After the program/erase command is issued, the auto-program/erase algorithms will program/erase and verify the specified page, sector/block locations. The system executes program commands on a byte-by-byte or page (256 bytes) basis. The system executes the erase command on a 4K-byte sector, a 32K-byte/64K-byte block, or the entire chip.

The device includes a status register that displays the chip's status and provides an easy-to-use interface. The status read command can be issued to detect the completion status of a program or erase operation via the WIP bit. When the device is not in operation, and CS# is high, it enters standby mode. The MX25L3233F utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after 100,000 program and erase cycles.
