2. GENERAL DESCRIPTION
MX25R6435F is 64Mb bits Serial NOR Flash memory, which is configured as 8,388,608 x 8 internally. When it is in four I/O mode, the structure becomes 16,777,216 bits x 4 or 33,554,432 bits x 2. MX25R6435F feature 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# pin and RESET#/HOLD# pin become SIO0 pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.
The MX25R6435F MXSMIO® (Serial Multi I/O) provides 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 sector/block locations will be executed. Program command is executed on byte basis, or page (256 bytes) basis, or word basis for erase command is executed on sector (4K-byte) or block (32K-byte), or block (64K-byte), 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.
The MX25R6435F utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after 100,000 program and erase cycles.
