MX25V1635FM1I Flash Memory: Features, Pinout, and Datasheet

MX25V1635FM1I is a 16MB Serial NOR Flash memory with a 2,097,152 x 8 internal layout. When in four  I/O modes, the structure becomes 4,194,304 bits x 4 or 8,388,608 bits x 2.

The MX25V1635FM1I has a serial peripheral interface and software protocol that allows it to operate on a basic 3-wire bus when used in a single I/O mode. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SDO) (SO). The device can be accessed serially via the CS# input.

When in two I/O read modes, the SI and SO pins become SIO0 and SIO1 for address/dummy bits input and data output, respectively. When it is in four I/O read modes, the SI pin, SO pin, WP# pin, and HOLD# pin become SIO0 pin, SIO1 pin,  SIO2  pin, and SIO3 pin for address/dummy bits input and data output.

On the full chip, the MX25V1635F MXSMIO® (Serial Multi I/O) allows sequential read operation.

Following the program/erase command, auto program/erase algorithms will program/erase and validate the specified page, sector, or block locations. Program commands are executed on a byte, page (256 bytes), or word basis. A 4K-byte sector, a 32KB block (32K-byte), a 64K-byte block, or an entire chip can all be erased with the Erase command.

By showing the chip state, a status register is constructed to provide the user with ease of interaction. The WIP bit can be used to determine whether a program is complete or if an erase operation is in the process using the status read command.

Advanced security features improve the protection and security functions; for more information, read the security features section.

Macronix 's unique memory cell is used in the MX25V1635FM1I, which dependably maintains memory contents even after 100,000 programs and erase cycles.
